FAQ
- Can I boot from an emulated floppy or hard disk?
Yes you can!
- Does this require a special driver or INIT?
No software is required for floppy emulation on any system. For Macintosh HD20 hard disk emulation, most supported Mac models require no software, though the Mac 512K requires Apple’s HD20 Init.
- What types of disk image files are supported?
Macintosh: 400K, 800K, or 1.4MB floppy disk images in raw .dsk format or DiskCopy 4.2 .image format, or hard disk images up to 2GB in raw format. Lisa: 400K or 800K floppy disk images in DiskCopy 4.2 format. Apple II: 140K floppy disk images in .DSK, .DO, .PO, .NIB, .WOZ, or .2MG format, 800K floppy disk images in .DSK, .DO, .PO, .2MG, and DiskCopy 4.2 format, or hard disk images up to 2 GB in .PO, .2MG, or .HDV format. The maximum size of a ProDOS volume is 32 MB, so larger hard disk images must be formatted as HFS.
- Can I write to the emulated disk, as well as read from it?
Yes, for all but Apple II NIB and WOZ format images. Note that writing to a DiskCopy 4.2 disk image does not modify its stored checksums – see details in the usage instructions.
- Can I format the emulated disk?
Yes for hard disk emulation, no for floppy emulation. Floppy Emu emulates standard sector-by-sector floppy writing, as occurs with normal I/O operations such as copying files or saving data from within a program. Instead of formatting a blank disk, use one of the provided blank disk images.
- Can I back-up old floppies using tools like Disk Copy 4.2 or Copy II Plus?
Yes, with some conditions. Many disk copy programs perform a simultaneous format-and-write of the destination floppy, which creates problems (see previous answer about formatting), and requires special attention when copying. See the manual for details.
- Can the Emu work with copy-protected disks?
The hardware is designed to work with unprotected disks using standard sector and disk formats. Some copy-protection schemes may work, including some Apple II WOZ and NIB disk images, but this isn’t a hardcore cracking tool.
- Can I emulate multiple floppies at once?
Floppy Emu can store as many disk image files as your SD card will hold, but only one can be “inserted” in the drive at any given time.
- Can I connect two Floppy Emus to the same computer?
Yes, if they are connected to separate disk ports. For the Apple II, a Floppy Emu board can also be placed at the end of a daisy chain of other disk drives. The Emu doesn’t have a daisy-chain output port, and can’t be daisy-chained on the Lisa or Macintosh.
- How can I copy documents from an old Apple II or Mac floppy to a modern PC?
Use Floppy Emu to copy the documents to a blank disk image, then put the SD card in your PC and use a disk image utility program like CiderPress or HFVExplorer to open the disk image and retrieve the files. See the manual for details.

Neat!!!
FANTASTIC!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
A device like this is desperately needed. There must be thousands of old Mac enthusiasts stuck with no good way to bridge internet disk images downloaded to PCs to their old Apple systems. I’d buy one from you in 2 seconds. It’d pay for at least some of your mortgage 🙂
Whoah, this is really cool! I have recently acquired a Macintosh SE and was hoping to get it working after hearing its HDD make unhappy noises. I saw the HxC floppy emulator a while back but I was disappointed to find out that it would never work with my old Mac. Your project has given me hope, though! I’ve subscribed to your blog’s feed and I hope to eventually build one of these floppy emulators, too.
Thank you, and keep up the good work!
Absolutely amazed with your project. Congratulations.
As the other comments mentioned, is a vital addon in case of old machines like mine, with the floppy unit out of order.
Keep us posted!
Kind regards from Madrid!
Interesting
Wonder if this would word with an Apple IIgs?
If not directly then maybe coupled with a daisy-chain board?
Hello!
Could you also implement support for Roland’s Quick Disks?
It’s not floppy protocol but it should be easier than that and has a huge target group as nobody has already done it till now and there are many instruments using them and no disk’s to buy..
I’m afraid not. From the limited information available about Quick Disks, it looks like it has a completely different data cabling and data format.
Hi Steve
Just to let you know that I received your floppy emu and I have to say it works like a charm! Thank you for the quick delivery to Gibraltar.
Best regards
Francis
A very happy customer 🙂
What would be an amazing (and probably easily-implementable) feature for this device would be Apple HD20 emulation.
For those who aren’t aware, the HD20 was a hard drive that connected to the Mac Plus via the external floppy port. The Mac Plus was released with a draft SCSI implementation, and as a result it can sometimes be tricky to get SCSI drives to play nice with it– mine only likes one specific 40MB drive combined with one specific enclosure. The HD20 always works (slowly), but it’s rare, expensive, pushing 30 years old, and uses a hard drive with a completely proprietary interface (not SASI, SCSI, MFM/RLL, IDE, or anything else.)
Yup, I’ve been investigating HD20 emulation and made some small progress on it. Read more here: http://www.bigmessowires.com/2014/02/06/emulating-the-apple-hd20/
Sweet, I hope it turns out to be possible! I’ve just voted with my wallet and bought one. Looking forward to using my Plus without swapping physical floppies if nothing else 🙂
I’d love to see a video how to build this! Or even a schematic of the emu would be great!
See http://www.bigmessowires.com/2012/12/15/build-your-own-floppy-emu/
Thank you Steve!!!
Just received my Mac Floppy Emu. Works great on my Mac SE/30. I’d be very interested in getting this to work on an Apple II, such as the Apple IIgs or IIc Plus. I tried it on both, but can’t get it to be recognized. I’d be more than happy to help out in getting this drive to work on the Apple II. I also have an Apple Lisa 2, so I can also help out in testing on that system.
Bryan, with the Apple IIs, was the Mac Floppy Emu in a external drive box with a daisy-chain port?
Some people on the 68kmla forum had partial success getting it to work on an Apple IIgs. See http://68kmla.org/forums/viewtopic.php?f=29&t=22517 It worked when connected to the pass-through board taken from an Apple 3.5 drive, but not when connected directly to the floppy port. I’m not really an Apple II guy so I’m not sure what’s up, but there are some good ideas in that forum thread if you want to follow them up.
Steve, I got it to work, using the information at the 68kmla site. There’s something about the Sony CXD1085B that allows this combination to work. Thanks for the tip!
Hi Steve,
when are you planning to get a new batch of floppy emu?
Thanks
Nicolas
One suggestion that you might want to consider in a future version… Ability to copy dsk image files within the Emu interface. I keep the blank800.dsk on the SD card, but I’d like to be able to make a copy of it on-the-fly and then use the copy, instead of taking the SD card and performing the copy elsewhere.
Hi!
I really like your project and just bought one Macintosh Floppy Emulator “used” on eBay in germany.
It really does work with my Mac 128k, great!
One question/suggestion though:
Is it possible to preselect one disk image so that it automatically gets inserted on power-up?
If this isn’t yet implemented, you could look for a text file containing the filename or even a list of preselected images.
The C64 SD-Card project SD2IEC does support this… 🙂
Good idea!
Yes! It would be great… 🙂
And also the feature to copy/duplicate a disk image directly on the device without the need to connect the memory card to a PC…
Sorry for the spamming. 😉
Where is a good place I can download Disk Images “dsk” for my macintosh plus? I use MacintoshGarden.org but all the files from there are “.SIT”. Does the floppy emu only recognize .DSK”?
DSK is not a normal floppy disk format for the Macintosh. The only DSK files I’ve found for the Mac are hard disk images. You can open SIT and SEA files by using the StuffIt for Windows or Mac. When you extract the images from SIT, make sure the image files have the .img file extension. Macintosh Floppy Emu can read .img files, but it won’t write to them. You can use the Disk Copy conversion tool that is linked on this page to convert the .img file to .DSK.
Thank you Bryan but I kind of need a visual. A YouTube video on how to covert my files from macintosh garden into a DSK would nice. I’m very eager to purchase the Mac Emu but i’d like to understand how to do this process before I buy the Emu. @Steve Chamberlin hope you’re reading!
I would love to have this but getting it to fit my Powerbook Duo might be a problem. Duo never had internal floppy disk drive (take that iMac!!) and the external drive support is via dock that uses propriety 20-pin square connector. There are large dock that do have internal disk drive but they are often over $100 on eBay, untested, and the dock are known to have bad power supply so I’d have to pay more on repairs just to make it work for files.
Anyone have any idea how or where could I get a cable that uses the square connector that was widely used in early Powerbooks?
Hi Eric,
you might want to build your own cable using a HDI-20 connector taken from an external 1.44 MB drive.
There is a few available on eBay.

Why don’t you support the full 532 bytes per sector? Is there any limitation in your system architecture, or was ist just because 512 bytes equals one SD card block? In this case, one floppy disk sector could be stored in two SD card blocks. Of course this would waste some storage capacity, but with today’s 2GB cards it would be acceptable.
I’m assuming the reason for the 512 bytes has nothing to do the emulator, and everything to do with holding down to standards. HFS standard is 512 bytes per sector. Apple’s DiskCopy utility therefore supports the 512 bytes standard. While true that the 512 byte setting can be changed, it would then throw off the standard, and you might run into incompatibility problems with many other utilities that use DiskCopy’s disk image format.
The other way: 524 bytes per sector is the standard for 400k and 800k floppies and the format used by Apple’s DiskCopy utility. *.dc42 files have 524 bytes per sector, and they have to be stripped down to 512 bytes to be used with the emulator. This causes incompatibilities with LisaOS and MFS.
532 bytes is Apple’s block size for harddisks.
https://68kmla.org/wiki/index.php?title=DiskCopy_4.2_format_specification
The classic Mac OS uses 512 bytes of data per sector for both HFS and MFS – that can’t be changed. True, the disk stores a few additional bytes per sector, but they’re not data bytes and the OS doesn’t use them. They’re called “tag bytes” and are a hold-over from the days of the Lisa, but are basically unused by the Mac. DiskCopy stores the extra tag bytes for completeness’ sake, but if you check any Mac disk image you’ll see the tag bytes are just all zeroes.
DiskCopy images work with MacFloppyEmu just fine unchanged. I can download DiskCopy images right off the Apple site, and the emulator works with them. If however you want to write to the images, then you you have to convert the *.dc42 format to raw .dsk format, using the utility linked on this page. The emulator is advertised not to work with the Apple Lisa, but not because of the reasons with the sector size of the image file. So working with LisaOS would not be an issue.
Does this come with floppy images?
Would be wonderful if this could be tweaked to work with Apple 2 “SmartPort” signaling as well.
I purchased the floppy emu a few weeks ago and I’ve use it with my two Mac 512k’s, works flawlessly. A fantastic product.
Any thought to designing an enclosure for this? …You can 3D print them and sell them. 🙂
I’d love to. My 3D printer doesn’t have a large enough print area, though, and the prints are slow and unreliable enough that I don’t think it would be practical. If anyone else wants to try designing an enclosure, I’d be happy to work out a revenue share, or just refer interested people to them.
I just wanted to chime in a say that I just bought one of these… and it works great. I just had to reformat my SD card to Fat32 and MOST files show up and are accessible. I’ve been downloading games, but I think I might want to try and find some apps. I have an ImageWriter II that I want to make use of. 🙂
I bought your gadget just in time before it is out of stock.
I want to know how to convert 1.4MB image into 800K. My SE doesn’t support 1.4MB.
800K is a lower capacity disk format, so unfortunately there’s no simple conversion possible from 1.4MB. You can’t fit 1.4MB of data into 800K of space. Most software from the early Macintosh era was sold on both 800K and 1.4MB disks, so you’ll need to find the right disk image for the software you’re using. Or copy the files from a single 1.4MB disk onto two 800K disks, and use them that way.
I just got my Floppy Emu and love it, my Macintosh Plus is alive again! I highly recommend if your thinking of buying the Floppy Emu to buy the one with the extension cable, It would be a pain to have to lean over the mac every time you want to insert a new disk.
Steve, my Plus can only read the 400k and 800k .dsk images but I have an Apple HD20 (NOT SCSI) which is on my floppy drive port. So is there any chance of seeing a firmware update that would allow Floppy Emu to “mount” a 20mb .dsk? That would make it posable to run all my whole system off the FE and not need the noise Apple HD20 running!
Anyways thanks for a great tool for bring life back to dusty old Macs!
Yes, I think HD20 emulation is possible, and I did some research into it a few months ago – http://www.bigmessowires.com/2014/02/06/emulating-the-apple-hd20/ It’s still a long way from a practical reality though.
this type can apply to 3 module FDD used for NEC PC-9801 ?
No, sorry. Floppy Emu is for classic Macintosh computers only.
Can anyone point me in the right direction where I can find a disk image that will work on my Macintosh Plus? I just got my Floppy Emu and I only have disk images that work on my 512 K Macintosh. I’ve tried the apple support page and Macintosh Garden and I’ve even tried a couple other sites I googled. Would be awesome if I get this Mac Plus back to life. Thank you guys!
The Plus will work with any disk image that the 512K does, as well as many more. Check the instructions included with your Floppy Emu for a link to an archive of some other disk images too. Most things from Macintosh Garden should work as well, for example all of the 800K system disk images at http://macintoshgarden.org/apps/macintosh-system-6x
Okay I downloaded the link you gave me. Now I have a “.sit”What should I use to extract it?
There are free utilities available for Windows, MacOSX and Linux that can unpack a Stuffit archive.
The easiest way to get started is with the link in the printed instructions that come with the Floppy Emu. This has a dozen or so disk images, already in the right format. All the 400K and 800K images should work with the Plus, like Dark Castle and MacPaint and System 6.
Stuff from Macintosh Garden can be harder. Often the files are .sit (StuffIt archive – similar to a zip file) or .sea (self-extracting archive, a program you have to run on a classic Mac). If you can find versions of the software you want in DiskCopy II format or raw image format, download those instead, as they’ll work directly with Floppy Emu and save you a LOT of work.
If the software you want is only available as a .sit file, there are programs for OS X and Windows that will directly uncompress a .sit archive, but I haven’t yet found one that I like. If you can find a good one, you could simplify things a little. Steven Hirsch, do you have a recommendation?
Otherwise to open a StuffIt archive, you’ll need a Mac emulator program like Mini vMac, a Mac ROM file, and a copy of the classic StuffIt program. There are several versions of the StuffIt program, which produce different version of .sit files. Newer versions of StuffIt can open older .sit files, but older StuffIts can’t open newer .sit files. The newest StuffIts won’t run on a Mac Plus, though, which can make things complicated. The basic method is to run an emulator like Mini vMac (my preference) or Basilisk II (if you need something newer), launch a copy of StuffIt, and use it to uncompress the .sit file. This will typically give you a DiskCopy II file, but it’s still inside the emulator. Use the Mini vMac plugins ImportFl and ExportFl (http://www.gryphel.com/c/minivmac/extras/importfl/index.html) to move files between the emulator and the host computer.
Unless I’m misremembering something, I believe I’ve used this:
hirsch@z87:/usr/local/bin32$ ./unstuff
unstuff 5.2.0.611 2001/06/28 15:24 – archive expander
Usage: unstuff [-option[=value]] [–option[=value]] (archives…)
-d= –destination=path destination directory for expanded files
-e= –eol=[unix|win|mac] text type for expanded files

-m= –macbinary=[off|auto|on] MacBinary output option for two-fork expanded files
-p= –password=password archive password
-q –quiet suppresses messages
-t= –text=[off|auto|on] text conversion for expanded files
-v –version shows version information
See unstuff.html for more information.
Unfortunately, I do not recall exactly where it came from. There is a version of Aladdin unstuff for Windows, AFAIK, but I’ve never used it.
Here’s a link for a free-as-in-beer Windows tool:
http://my.smithmicro.com/stuffit-expander-windows.html
I have not used it and cannot vouch for it one way or the other.
also, as we know this also works with the Apple IIgs, as long as you install this into a 800k 3.5 external HD floppy drive.
but wouldn’t it be cool is maybe someone could load up a boat load of images plug it into the back of a IIgs and Start Rocking in vintage App land, W/O needing the 800k floppy enclosure? I have some IIgs’s here.
I really would like to send you a IIgs for free, so you can have it laying around maybe it will give you creative inspiration
for future projects.?
here is a place with all the images.
http://asciiexpress.net/gameserver/
after all a IIgs will do just about everything including all the Apple II software as well.
I’ll second, third and fourth the request for Apple IIgs and, as an added bonus, Apple //c SmartPort compatibility. In the interim, I will temporarily sacrifice an AppleDisk 3.5 to make use of the passthrough board.
Hello,
I’m just received my Floppy Emu. i went out to Best Buy and purchased a cheap 8 gb SanDisk Ultra (40mb/s) . Brought it home, plugged it into my Mbpro Retina. Already pre-formatted FAT – so just copied some .dsk files to it and then put into my new Floppy Emu. Next, I plugged my Floppy Emu into my 1984 (April) original 128k Mac, and that was it. All the dsk files were easy to read/write to with no issue so far. I’m really excited about this. Lot to mess around with this weekend. Thank you so much!
Thanks for the great product and fast service! My floppy emu is working wonderfully. I love the lit LCD. The clear acrylic case took a little bit of assembling, but the finished product looks slick and professional.
Food for thought: As mentioned performance varies with SD card. What about attaching some SPI-Based RAM to the MCU? Open the disk images in RAM for read/write/format access. Then when the Emulator goes idle, or gets an eject command, it commences the write to the SD card at that point?
Good thought. I considered that approach, but eventually decided against it. Performance is mostly determined by the speed of the Macintosh floppy interface, and not the SD card. For reading, there wouldn’t be any noticeable benefit to caching the disk image in RAM. For writing, it might be anywhere from no benefit to perhaps 2x faster depending on the card. I decided it wasn’t really worth the extra complexity.
The kit arrived in good time given it travelled all the way to UK. It works well and I’m looking forward to putting it to good use. One thing, if thing it be, I wish I’d ordered the plastic case for it at the same time as the order. It makes me nervous sitting on the desk there in all it’s unprotected glory. But well done you for making it.
Keep the board off of metal surfaces and you’ll be fine. 🙂 I’ve used a pair of Emus without cases for about two years, so they’re pretty rugged in normal use. The case does add a nice touch of polish, though!
OK, thanks for that. I’ve just ordered a case in any event. It seems a good idea. I wish I had done so in the first place but no worries. A super piece of kit for those who like fooling around with old Macs, even if I don’t know why. Next project id capacitor replacement on an SE/30. Terrifying for someone with fingers as stubby as mine!
How does one enable the backlight?
New Floppy Emus have the backlight enabled by default. For older ones, it varies depending on the board revision. For most boards, you can add a piece of wire at the location labeled R5 on the main board, or between LIGHT and GND on the LCD board. See more info here: http://www.bigmessowires.com/2014/04/04/floppy-emu-backlight/
I got the one I ordered for my Classic II yesterday! It works great, and looks fantastic in the clear case. I also got it set up in HD20 mode. My only comment is that I found the firmware updating instructions ambiguous — hold down next and prev buttons, then press and release reset… does that mean keep holding the next and prev buttons until the updating is done, or let go of them? At any rate, I got it to work, but I was a bit nervous about messing it up.
Well, the box kit arrived and after an ‘interesting’ time putting it together, what a darling it looks. I installed the HD20 software and it works a treat on the Classic. All in all a super piece of kit. One query, as the words read I can get HD20 mode running on an SE/30 if I install and boot from a drive containing HD20init. Is that correct? Either way, it’s great. Thanks for working it all out.
The HD20 Init is only for the Mac 128K and 512K, and the SE/30 doesn’t support HD20 mode at all. Sorry for the confusion – I’ve edited the compatibility paragraph to hopefully make this clearer.
Put together the new case, looks great! I Do have a tip for putting it together, masking tape, makes all the difference when you have to flip it over to tighten the screws!
Steve thank you for the HD20 firmware update, being about to run my Mac plus without using the noisy Apple HD20 is amazing!
Hi,
I curious if your floppy drive EMU could be adapted to work as a as though it was a prototype Macintosh 128k with a Twiggy floppy drive disk that I recently restored and archived.
I have 2 versions of the Twiggy Mac 128k’s motherboard ROM’s which will work on any standard production Macintosh 128k. I also have 13 archived twiggy disk images to test with.
Please let me know if you can help me with this project.
Thanks,
Adam Goolevitch
778-885-2312
If you can make Twiggy drives work with just a ROM swap in the Macintosh, then it’s likely that Floppy Emu could be modified to emulate the Twiggy drive. If you send me whatever technical info you have about the drive, the disk format, and the ROM, I’ll take a look at it.
I’m not getting it… Why would we want to emulate twiggy drives?
The only reason we are even emulating Sony drives is that 98-percent of content for the Lisa are only 400K disk images. If there were twiggy disk images floating about, then that would be one thing. But even then, it is easy to just copy the files from the twiggy disk image to the 400K disk image. We should actually be running away from twiggy drives and disk images.
Hi, I received Macintosh Floppy Emu #0302
Very professional PCB (not really big mess :-)! and wonderful firmsoftware !! Merci
Best regards,
Francis
#302 and growing!
Mine is #91… This and the CFFA boards for the Apple II are two of the finest hobbiest-produced products I’ve ever seen. It is amazing how much the MFE has been upgraded, despite not needing additional hardware to address these new features. It shows that Steve designed the product right when it came to future growth.
Meanwhile, the first Apple IIGS Floppy Emu! https://www.facebook.com/media/set/?set=oa.10153725996848677&type=1
Cool. I need to learn what that magic pass-through board in the A9M0106 floppy drive does, because whatever it does, it makes Floppy Emu work on the IIgs. Maybe I can duplicate the functionality in the Floppy Emu, then it could work directly without needing the pass-through board.
It would be even more ideal if Floppy Emu could pretend to be a Unidisk 3.5. That would extend functionality to the Apple IIc in addition to IIgs. There is documentation on the bus protocol floating around in the A2 community. Just say the word and I’ll round it up for you.
Maybe… if you have a link or pointer, that would be helpful.
@Bryan March: it’s worthwhile to work with Twiggies because the Lisa 1 is a historic machine, of course! The software that ran on a Lisa 1—the first GUI environment for a personal computer ever made—will only run on a Lisa 1. There are differences between versions 1.0 and the versions that came later for the Lisa 2.
Twiggy disks are now 32 years old, and many are degrading or already useless. With the emulator, someone could easily boot up a disk utility like BLU and save some of their old media, or install a version of the Office System or the Workshop from images and use that to save their old documents.
There is plenty of Lisa software that hasn’t been backed up onto modern media yet. Twiggy-capable emulators would help.
Also, there definitely are Twiggy disk images floating around:
http://bitsavers.trailing-edge.com/bits/Apple/Lisa/twiggy/
http://bitsavers.trailing-edge.com/bits/Apple/Lisa/workshop_1.0/
http://bitsavers.trailing-edge.com/bits/Apple/Lisa/monitor/
Finally, there is as yet no way to “just copy the files from the twiggy disk image to the 400K disk image” other than stuff like:
– copy disk image to a real Twiggy using a Lisa 1.
– copy file from the Twiggy to a ProFile hard drive.
– plug the ProFile into a Lisa 2.
– copy file from the ProFile to a 400k drive.
and that’s assuming that the newer Lisa OS running on the Lisa 2 can read the old OS’s filesystem on the ProFile (the filesystem changed between versions). Don’t know whether that would actually work.
So, there are some good reasons to emulate Twiggy drives.
A Twiggy mode for Floppy Emu would certainly help Lisa 1 owners for backing up their disks. But I’m not sure it would really help with copying files to a 400K disk or disk image. You could make a Twiggy disk image with the Lisa 1, but then what would you do with that on your Lisa 2? Maybe somebody in the Lisa community could write a software utility to parse the contents of a Twiggy disk image, extract the Lisa filesystem contents, and create a new 400K disk image with those contents.
I just sent a tarball of information on the Apple 2 Unidisk to your e-mail address. Gmail works very hard to strip attachments and dump outgoing mail in the bitbucket, so let me know if you fail to receive it?
The 400k thing is really a red herring, but I remarked on it it since Bryan brought it up.
Lisa 1 and Lisa 2 are very similar computers with some interoperability, but from a conservation perspective, it’s probably more worthwhile to think of them as separate machines with separate filesystems, operating systems, and file formats.
There are probably not a lot of Lisa 1 owners out there who are just dying for a way to finally get their Twiggy docs on a 3.5″ 400k diskette. Even if there were, a Twiggy holds 870k, so it might be a tight fit.
Instead, the real value of a Twiggy emulator comes from things like:
(1) direct Twiggy->disk image backups
(2) making it easy to load/install software onto the Lisa from images, like BLU, the Office System, and the Workshop. This in turn really opens up the number of backup options people have available for their data.
(3) making it easy to create and test “experimental” disk images, in order to reverse-engineer the filesystem.
Item 3 cannot be done in an emulator, since no emulator exists yet for the Lisa 1. Of course, having an easy way to try out arbitrary boot disks in a Lisa would probably speed the development of viable emulators, too.
@Steve Hirsch – got your email, thanks!
Wow, absolutely godsmacked.
Here’s a very happy, just new owner. Excellent design. I left the paper on the acrycl case around the mac icon, looks better IMHO.
A floppy emu must be sold/sent to Steve Wozniak, much better than this flash pci memory biz he’s now in .. At least he’s gonna get good internet speeds down under in Aussie land.
Can’t wait until a universal apple ][, unidisk, mac, hd20 (or hd8192 :)) emulation is fully functional. Or I’ll just have to buy another one 🙂
THANK YOU FOR YOUR EFFORT, YOU MADE BY DAY, PROBABLY MONTH+ !
Hi, It says that there is HD20 emulation that is compatible with the classic 2, but with mine when I gives me the question mark floppy. It works perfect with floppy drives however.
Hi Byron, please send me an email with the details and I’ll look into it. With some Macs, you can’t boot from the HD20, but you can mount the HD20 after booting from another disk. I think this is the case with the IIsi, though I’d need to double-check. The Classic 2 might be the same way?
Hi, I am using it on Apple II with firmware apple-II-0.1D-F3. It works nice, but have problem because it cannot remember selected disk on restart(probably I am wrong but…). On each restart I have to select disk. Is it possible to keep somewhere previously selected disk and on restart on computer to boot again from it.
thank you great device 🙂
If you restart the computer with CTRL+Apple+RESET, the currently inserted Floppy Emu disk will remain “inserted” in the virtual disk drive. But if you turn the computer off, then on, the Floppy Emu loses power and resets, and will return to the disk selection menu.
A few people have suggested saving the name of the current disk in Emu’s internal EEPROM, and automatically re-inserting it the next time the Emu starts up. I’m not sure if that would be helpful, or annoying, and whether it would be appropriate for Mac disks, Apple II disks, or both. Any opinions? For now I’ve elected to keep it simple and not do any automatic re-insertion of old disks.
The Floppy Emu works great!
Started a YouTube series using it with a Mac 512k:
https://youtu.be/PBz25fWz5ds
I agree. Keep it simple.
Hi Steve,
This is Steve 🙂
I have a few questions for you. I upgraded my emu firmware for the Mac+Lisa firmware this week.
1- if I plan/want to use it with an Apple IIc/IIgs eventually, Is there a simple way to switch from one emulation to another?
2- do I need to update both files each tine, or only the second step is enough?
3- pictures of the case do not show the built-in 19 pin DB-9 side, but I suppose it fits well. Going to order one now.
Also, I never tried it, but is it possible to use folders with the emu on the SD card? Could simplify images management for different system types.
Thanks
To switch between the Apple II and the Mac+Lisa, you will need to switch which firmware is installed on the Floppy Emu. Yes, you need to update both firmware files (one is for the CPLD chip and one for the AVR microcontroller). Updating the firmware takes about 1 minute.
Yes, you can use folders to organize the floppy disk images on the SD card.
Here’s a photo of the acrylic case used with an Emu board with the built-in DB19 floppy connector: http://www.bigmessowires.com/wp-content/uploads/2014/10/20141024_200728.jpg
Hi Steve,
I was not sure if the CPLD firmware were identical or different for each usage.
What would be cool is if we could put both CPDL/AVR firmware in a specific folder (say appleii and mac folder) and from there having a way to trigger a process (ex: hit reset/select) and have the device able to initiate the firmware swap in an automated way. I guess the board is not “smart” enough to do this…
Thanks for the picture of the case. I placed my order yesterday with one of the new universal cable, even if I may not have a real requirement for it. Could be used for my IIgs ROM3, but it also have the CFFA3000 card inserted. Maybe I’ll be able to use both item for transferring data from one to the other.
Maybe eventually you’ll be able to emulate other floppies (Atari, Commodore)…
Hi again Steve,
Any chance the Floppy Emu will do something like this:
https://www.facebook.com/photo.php?fbid=1468153686815336&set=gm.10154084940178677&type=1
Both an Apple III? It needs to be connected in place of the Internal FDD, because the Apple III is hardwired in ROM to both from this drive only. I want it 🙂
I don’t know much about the Apple III, but from what I read in that Facebook post, it sounds like the Floppy Emu should work if you use the Emu’s Apple II firmware and this special cable: https://www.tindie.com/products/option8/apple-iii-disk-ii-cable/
I’ll give it a chance on an Apple III and let you know what it does.
If I want to use the Apple III Disk II Cable in the link with your Universal Adapter Extension Cable, I guess I should order the female version of the former cable. Does that make sense?
The Apple III Disk II Cable is only 13″ long and need to be connected internally in the Apple III (to boot from), which mean the EMU will either be on the back of the computer (not ideal) or I’ll have the cable running trough the cover, and it becomes ugly (or a Big Mess of Wires, your choice!).
I’m not certain, but it looks like you could combine the male version of that Apple III cable with the detachable part of the normal Floppy Emu extension cable (or any 20-pin ribbon cable) to make a single longer cable. It’s a little confusing, but I think the female version of the Apple III cable is meant to go directly between the Apple III and the drive electronics, whereas the male version is meant to be connected to a second cable.
First, I need to confess it was late 911pm for me) when I wrote my previous comment, and my brain was not at its best. I wrote “the female version” while I really meant “the male version”.
The other thing I have not realized is the fact that your standard cable already had a detachable DB-19 board. I was under the impression that the ribbon cable was soldered to the DB-19 pins. I have the cable in front of me now, and I can see it clearly.
That said, you’re right. I will order a male Apple III Disk II Cable and I should be able to connect and boot from the Floppy EMU on my Apple III.
The female Apple III Disk II Cable can probably be connected directly to the Floppy EMU 20 pin socket on the PCB. But the 13″ length will make it very weird to use.
Did you attend Kansas Fest this year?
I got mine in today and I love it. One question: I am using it with a Apple //gs ROM03, if I am in Smartport mode and hooked directly to the system, it boots fine. If I hook into the 3.5 drive and try to boot, it doesn’t work. Would the Universal Adapter Extension Cable help with this or is it the way things are? I did update the firmware to the apple 2 firmware before using. Other than that small issue, I love it. I was able to move some files I haven’t seen for years to my PC using floppy emu and ciderpress. Thank you for making it.
I’m pretty sure that behavior is normal and is a limitation of the Apple II hardware. When booting, the Apple II can only check drive 1 for a slot, not drive 2. When you connect the Floppy Emu daisy-chained to a 3.5 drive, then the 3.5 drive will be slot 5 drive 1 and the Emu will be slot 5 drive 2. So the computer checks the 3.5 drive, sees that there’s no disk there (or not a bootable disk), and gives up. If you use that configuration and boot from a 3.5 inch floppy, then you should still be able to access the Floppy Emu as a second disk. You’ve made me curious whether there’s any work-around for this. If you connected a second 3.5 drive and then the Floppy Emu, I think the two 3.5 drives would be slot 5 drives 1 and 2, and then the Emu would be slot 2 drive 1, which might be bootable. Or you could install a separate disk controller card, and connect either the 3.5 drive or the Emu to that, so that it can be drive 1 for that slot.
The Apple IIgs only scans the $Cx00 slot ROMs on boot, the connecting of 2 3.5″ drives will not work. I would check out ProBOOT to see if it can do it: http://www.sheppyware.net/apple-ii-software/proboot.html
Yes, it requires an extra 3.5″ boot disk to store ProBOOT if you don’t have any other mass storage.
The firmware update on my latest Emu has been plagued with the “wrong CPLD” error, though on my older (purple) board, it worked with no issue. I copied both the .xvf and .bin files to the SD at the same time, booted my Mac Classic II with the Emu connected, and then shut down, leaving the safe to power down dialog up so that the Emu had power, but the Mac OS wasn’t running.
As soon as I complete the first part of the update (the .xvf file) I get the frowny “wrong CPLD” error–that is, before I’ve even had the chance to run part two. I ran part two, and the things seem fine, but if I hit the reset (or power down and back up, which is what happens because of the status of the Mac as mentioned above) I get the frowny face again.
I’ve gone back to the non-hd20 firmware with no issues and tried again with the same result.
Any idea why it might not be working?
Seeing “wrong cpld” after installing the first part is normal, because the two halves of the firmware aren’t in sync yet. Is it possible you installed the first part twice, but the second part not at all? This is a common mistake, since the two parts require similar but not identical buttons to initiate. This would explain the behavior you’re seeing.
Yea, I also was surprised when I switched the floppy emu to the Apple II firmware to see the CPDL error on screen. But once I did the second part it worked and never complain again.
I just received my Floppy Emu and it is working great. One question: In Smartport mode I have created four 32MB ProDOS images named smart0.po through smart3.po. The machine can boot from it but only sees two drives (slot 5 drives 1 and 2). Should it be able to see the other two drives?
There was a blog post here (http://www.bigmessowires.com/2015/07/13/smartport-firmware-update/) that said that the Smartport drives should appear as slot 5 drives 1 and 2 and slot 2 drives 1 and 2. But slot 2 on an Apple //c is the modem serial port.
This is an Apple //c with revision 0 firmware and I am using the latest apple-II-0.1J3-F6 Floppy Emu firmware.
Are all four of your ProDOS images displayed on the Floppy Emu’s LCD screen? On my //c with ROM 0 and apple-II-0.1J3-F6, it works as described, mounting 4 Smartport drives on S5 D1 and D2 and S2 D1 and D2. I’m not sure about the serial port mapping… maybe the ROM dynamically maps extra drives to a different slot, depending on whether the serial port is in use?
Yes, all four images are shown. Serialports are not connected to anything.
Accessing S2,D1 and D2 gives NO DEVICE CONNECTED.
I’ll try booting with a different disk image – this is the ProDOS User’s Disk and maybe it does something when it runs it’s startup program. I can try a plain ProDOS image.
I’m testing by running Apple II System Utilities v3.1 (which is on the first Smartport volume), and selecting the “list volumes” option. It shows the names of all four volumes, and the slots and drive numbers for each. I suppose it’s possible that you’ll get different results depending on what boot disk is used for the first Smartport volume – sorry I can’t say for sure.
I fired up the System Utilities disk and I am now able to access all 4 drives, both from the application and from BASIC. I can get to the drives from BASIC by setting PREFIX but I didn’t see a way to find out what slot and drive numbers the last two drives are associated with (if any). I’ll experiment some more, but it looks like this will work and I am all set. Thanks for the help!
I think the issue was the ProDOS version. It works fine when booted from ProDOS 2.0.3, and the four drives are mapped to slot 6 and slot 2.
All I can say is wow!!! I purchased the universal floppy emulator. Now granted, I personally only one a mac. But I have several friend that have some apples, so I thought it would be a great investment to go all in. I could not be happier. The quality of this is great! I have used it for my Mac Quadra 650 (for files only), But where I really think it shines, is using it as a HD for the Mac Plus! Thanks so much for a terrific piece of hardware…
According to this statement: ◾Reads and writes emulated 140K, 400K, 800K, or 1.4MB floppy disk images, or hard disk images up to 2GB
The floppy EMU can write disk images as well. I was wondering if this true? Or am I misreading the statement.
That means the emulated disks are readable and writable by the Mac or Apple II, as opposed to being read-only disks like a CD-ROM. But the Floppy Emu does not create new disk image files on the SD card, if that’s what you’re wondering. To create and edit disk images on a Windows or OSX computer, you can use tools like HFVExplorer or Ciderpress – see the FAQ above.
This is a great product! With my Mac Plus (which has a Micro Mac Accelerator installed) I am able to mount floppies from the EMU. But no matter what I do I can never get the Hard Disk part to work. I installed the firmware properly as the device works. Is it possible the firmware needs to be installed again? Every time I go into HD20 mode the screen says something like “disabled” or “write mode changed 6 (or 7, or 2)”.
I make disk files and floppies using HFV Explorer on Windows…. Is there a boot sequence I should follow? Do you have any tips?
I’ve heard from a Mac SE owner that his accelerator causes similar errors in HD20 mode – some kind of accelerator incompatibility it seems. Can you try removing the accelerator from your Mac Plus?
Thank you for replying. Today I did more digging and I found two pre-made hd20 disks that when inserted booted up the Plus. Without the Control Panel and Extension the Plus sees the upgrade as a 020. But this showed promise… I could not seem to format a disk, but that was with the upgrade turned on. I found a way to convert a disk into HFS, and once I turned off the “instruction cache” in the upgrade control panel, the disk mounts! Next is to make a disk and see if the Plus will format it.
Than you for the tip! Floppy mode works great with the upgrade turned on. What exactly am I doing by turning it off; what makes that work?
Hi, I have a flopy emu and it works great on my iiGS, of course once i’d read a bit more and found i mustnt have my 3.5″ floppy daisy-chained with the floppy emu on the end. Ok, generally np as I’m booting it into HD emulation mode or apple ii floppy emu modes and both work great! I’ll soon try it on my iie for floppy emulation.
However, one thing I just cant find how to do – how to cold boot a disk? my iiGS and my iie both have Z80 cards, how can I select then boot from a CP/M disk (physical floppy or emulated) with the floppy emu? has anyone done this? I may be missing something obvious or not understand enough about how apple ii’s work. my iie, btw has disk controllers in slot 5 and 6, so i could use either 19 or 20 pin connections on that machine if it helps..
cheers!
Hi iain, daisy-chaining with a 3.5″ Apple II drive is fine as long as you have the universal adapter with the switch set to the 3.5 position. To boot an Apple II from a 3.5″ or 5.25″ emulated floppy image, turn on the computer, select the desired disk from the Floppy Emu LCD menu, then press CTRL+Open Apple+RESET to reset the Apple II. Feel free to email me directly if you have other questions.
thanks, will try!
Hi Steve,
This item Apple Disk Drive A/B Switch and Cable, $15, it just allow to connect the drives to one cable, and use one at a time, but do not allow daisy chain or use both the EMU and the real floppy simultaneously. Do I get it correctly?
That’s right. The A/B cable is useful for owners of Lisas or Macs with only a single internal floppy connector. If your Mac has both an internal and an external floppy connector, then you don’t need it.
Great device !
On my IIgs, it works well as 3.5 device (did not test 5.25 on this guy) but on my //c+, I cannot make it work as a 3.5 device (here it works fine as 5.25):
neither connecting it externally with the universal adapter nor connecting it internally instead of the default 3.5 drive.
Any idea ?
Alain,
Do you have the ROM 3 version on your Iic? If not, that may be the issue.
Earlier this week I had a report from a //c+ user that 3.5 inch emulation didn’t work on his machine. I don’t have a //c+ myself, so I can’t directly verify that, but I will update when I learn more.
One thing that I can tell is:
(1) when I plug it inside the //c+ instead of the internal drive, the status led blinks, but it does not boot.
(2) when I just plug it to the outside connector, the status led does not light at all.
Unfortunately, I don’t have the skills to investigate further, such as trying to boot trace scenario (1) to find out where it fails.
It looks like the //c+ isn’t compatible with the current 3.5 inch emulation mode, sorry. Apparently it differs somehow from the 3.5 inch disk interface on the IIGS, which was the basis for the Floppy Emu design. As a temporary work-around if you need to mount 800K disk images on a //c+, you can mount them in Smartport mode instead of 3.5 inch mode. If I find a better solution, I’ll post an update here. My apologies for the misleading info – I’ve updated the user manual to reflect that the //c+ does not work in 3.5 inch mode.
I ordered my Floppy Emu on Friday June 5 and it arrived Monday June 8 which I thought was incredibly fast from the southern California to Maine over the weekend. I bought it for my MacPlus and my MacSE. It is amazing for the Macs.
I have an Apple //c (ROM 3) and want to use the Floppy Emus Smartport Hard Disk Emulation.
I have the Floppy Emu SN 0392, Clear Acrylic case and the Standard Adapter Extension Cable.
Do I need the Universal Adapter instead of the Standard Adapter?
Nope, you will be fine with the standard adapter for that configuration.
Is there anything like this that will run programs to my apple II+?
Hi Patrick, Floppy Emu is compatible with the entire Apple II series including the II+. See the user manual and feature list, above, for more details.
Hi guys,
I have come across a very interesting disk, which appears to be something that Larry Kenyon wrote. It is a test disk for the Sony 400k drive, with programs dating from July 1983. It looks as though this was used for the original configuring, testing, and variable speed control for the “new” Sony 400k drives that had not yet been approved by Steve Jobs at this point (still going for the Twiggy drives on the Macintosh).
You can actually control the different speeds of the sony drive, like a software gear shift.
This is a very exciting discovery. Perhaps this would be a useful utility for the Floppy EMU for the orignal Mac?
Let me know if you would like me to send you photos, or a copy of the disk or disk image to check it out.
Best regards,
Adam
Under Apple II it says “requires firmware update”. If I want to switch this between a Mac Plus and an Apple IIc, do I need to keep reflashing the firmware, or does the firmware update support both?
The two firmware (Mac/Lisa vs Apple II) are totally different and you need to reflash for each type of machine.
Thanks Steve!
Thank Steve! I’m number #612!! Hopefully will be able to help Steve get more of them into the hands of other vintage computer hobbyists! I’m a member of a non-profit group, the Vintage Computer Federation http://www.vintagecomputerfederation.org/ we do a number of shows around the country, and are affiliated with addtional shows around the globe. So it couldn’t hurt working with us. 🙂
Model B #801 arrived today. Case is a work of art and floppy emu works great on my //e so far. Easy setup and operation. Forgot to update firmware for Apple II at first, but update was easy. Default is Mac. Super fast shipping.
Just ordered the B model, can’t wait to get it. Wanted a case but they were out of stock. Any ETA on when those will be available?
Thanks, I expect to have more cases available by the time shipping resumes on the 29th.
Hello,
I just got my model B, I’m trying to get the firmware updated to run on my IIe Platinum. I have tried several 4gb microSD cards (smallest I could find,) and the device does not recognize them, despite all of them being formatted FAT-32. The screen reads a big question mark, with “No SD card? Card Error 10:5” when I try to boot it. I am trying to troubleshoot it and I am at a loss as for why it isn’t recognizing the cards. Any advice?
Another person recently had the same problem, and was able to resolve it by trying a different sd card. Or if there appears to be a hardware problem, you can return the board for a repair. I’m traveling this week with limited internet, but I’ll send you some specific suggested sd card models when I return home on Friday.
Cute and useful, good combination!
My Model-B has been up and running for about a week now! Together with my Mac Plus it has become the centrepiece of my establishment. I love it!
Hi Mike D, following up on your question: the card I’m currently using for the “vintage software collection” is a Kingston 4GB class 4 SD card, and the UPC code is 740617120639. The Floppy Emu should work with pretty much any SD or SDHC card, though. If you’ve tried several different cards and they all show a message saying “No SD card? Error 10:5”, then please contact me at the “more questions” email address above, for more troubleshooting or to arrange a return.
Found that SanDisk Ultra microSDHC UHS-I @8gb works as well. Just got my butt handed to me on Karateka and Conan. Nice product. Thanks!
Do you have something that works in the opposite direction? I have a vintage macintosh plus that i will be upgrading to G4. I want to be able to use the internal 800K or 1.44MB floppy drive but i need a device to control the drive with the 19-pin interface that connects to the host with USB. Do you make something like that?
I don’t, sorry. Can’t you use a standard USB floppy drive with the G4?
Thanks anyway, i wanted to avoid using an external mechanical eject drive for posterity reasons (I want the floppy bay to be useful) and i found a good solution that others may be interested in if they are doing the same build.
I actually opted for the Iomega LS120 (SuperDisk) drive as it can be modulated to read / write as little as 800KB and as much as 120MB. Plus, it has an auto-eject feature similar to that of the Macintosh. It is an IDE interface so i will be using an IDE to USB adapter. Thanks anyway!!
Great Product!!!!
I have been waiting a long time for a device like this. This is defiantly the crown jewel accessory for my retro Apple and Mac collection.
Is it possible to upgrade the firmware to allow multiple floppy images at the same time (like to have a boot disk and data disk mounted simultaneously)
Is there a way to connect an external LED for the access light? I’d like to try 3D printing my own case, that resembles (or fits into) either an Mac external floppy enclosure or an Apple II enclosure.
The hardware is designed to emulate one disk at a time. There’s no plug-and-play connection for external LEDs, but a few people have soldered extra wires to the PCB for similar purposes.
Apple II emulation of 3.5 inch disks is now also working on the Apple IIc+, with the newest firmware.
Hi there, I love your device and am so glad to see someone supporting our old hardware.
I tried to update the firmware on my model A, and something went wrong. Restarting, I couldn’t get past the error screen, and on a second restart I no longer get anything on the screen. The power light is on, but the screen is blank and the status light does not blink.
I have tried a bunch of button presses and combinations but to no effect. Is there a way for me to revive this unit?
Thanks!
Hi Jay, sorry to hear about your trouble. I sent you a follow-up support by email.
I just purchased a Model A + Universal Adapter + Acrylic case. 🙂
This is such a cool product, I think it is the creme de la creme of Apple retro storage devices. 🙂
the Video’s on YouTube sold me. Cannot wait to get my IIgs connected and booting 🙂
This is an amazing device! It helped bring my 128k Mac with a bad internal drive back to life. It’s really elegantly designed and I love the acrylic case.
Hi Steve,
I was recently listening to the RCR podcast (an episode from late last fall) and they talked a little bit about the FloppyEMU model B. Can’t remember who sneaked of it, but he said that the new version can emulate Apple II and Mac without a firmware change. Can you confirm if true? Maybe I misunderstood too…
Thanks
That’s not quite accurate. The newer model B can emulate all types of Apple II drives without the need for extra hardware, whereas the older model A requires a separate adapter if you need Apple II 3.5 inch disk support. See the compatibility table above for the complete details. Both models have separate firmware for Mac or Apple II support.
Thanks Steve
The episode 118 can be listened to here, at 55 minutes: http://host2.cyberears.com/29988.mp3
Paul really says there’s no firmware flash required, so his understanding is wrong!
Steve, do you know where I could buy a small(2-3 inches) disk cable to put on the board of the floppy emu to get the internal connector just outside the the emu case? I think it would need to be female to male.
Try DigiKey in their “rectangular cable assemblies” section. They have some 20-pin ribbon cables.
Question – given that one can only “mount” one disk image at a time, I’m wondering if the Emu can be used to do an Classic Mac OS installation to a real SCSI hard drive mounted in the Mac. I’m guessing the answer would be YES if there is an appropriate Disk Copy utility installed in the .DSK file one is booting. Restating the question, can I easily use the EMU to “image” a blank SCSI disk already installed in a Mac, as opposed to just booting the Mac.
Yes, you can do an OS install onto a hard disk, using disk images of the Apple installer floppies.
Hi Steve.
Will we see the “BMOW Floppy Emu Deluxe Bundle” back for sale/in stock someday?
Also do you ship to the UK?
Thanks,
Chris.
Yes and yes. I hope to have more stock ready in the next few days.
10th of May has come. True to your prediction: stock has returned.
Chris! Buy now! Who knows how many DB-19 connectors he will have left. Unless the efforts in getting new ones made was successful.
Have been waiting on these to come available. Hadn’t checked in a few days and just saw today they were available. Have a ][+, 2 //gs machines, a Mac Plus and Mac SE30 that I’d love to get booted back up again. Can’t wait til it arrives!
Just bought mine. Looking forward to getting it. Only thing I’m curious about, can you install a System to a Mac only using this? I.E. Can you ’emulate’ disk swaps without powering off the machine?
hello, i’m french and i use you floppy emul. Now i’m use it with the 2gs but with smartport, when i put 1,2,3 or 4 image disk, i have sometime “files not contiguous” what is the problem?
thanks.
The files must be in a contiguous range of sectors on the SD card, in order for optimal performance. If they’re not, you can delete all the files on the SD card and then copy them back. Or reformat the SD card, and then replace the files. A defragmenting tool should also work, but the other methods are easier. 🙂
thanks, it’s good now

Going to buy an Aplle //e ) Do you have shipment to Russia ? Also, will it work with AppleII clones like Franklin Ace machines ?
Yes, shipments can be sent to any country by US Postal Service First Class Package service. See the shipping rates on the product pages in the BMOW store. I don’t have any direct experience with the Franklin Ace, but in general if the computer is Apple II compatible then it should work.
I’ve been really happy with this unit. Allowed me to get my //gs back up and running again, which then turned into figuring out how to get the hard drive in it running again, and now a fully functional system again. Can’t wait to try it out on my old Macs… Great product, just wish I would have the patience to put the box together! LOL!
Hey, Steve I’ve been trying to get the emu to work on my Mac Plus, but to no avail. My Mac has a bad disk drive, and a disk icon with a question mark. When I try to boot from the 6.0.8.dsk, you see the icon change to a happy face, also see the track, and side numbers changing, then “idle” appears. But no boot. I’ve tried this with the other 800k or 400k .dsk images with the same results. Any ideas as to why no complete boot?
That’s hard to say without knowing the history of the machine – possibly it’s RAM-related? Send me an email or ask the Mac gurus as 68kmla.org for troubleshooting advice.
Ive had my Floppy Emu (Model B) for about a week now.
It is a MUST HAVE!
I previously had a MicroDrive, which was hard to put files on. Not with this! In disk emulation, all you have to do is drag the disk image to the folder. For HD, you have to open it in cider press. Still easier than the MD! And Micro SDs are EASY to find vs CF cards.
Its definitely faster than a regular old disk drive, but it is slower than a MicroDrive, which really doesn’t matter since coursing a 25 year old computer!
The only thing I wish it had was the ability to emulate the disk emulation and HD at the same time. I know, all you have to do is turn the computer off and on again, but still, it would then be perfect.
Instructions are a little unclear at a few spots, but after a day of trial and error, I finally figured it all out.
Overall, GREAT product!
Thanks, and let me know if there are specific sections of the instructions that need more fleshing out.
I know I probably shouldn’t post this on here and just email you, but its a question everyone might want to know the answer to.
When I plug the Floppy Emu into a 3.5 inch drive, my IIGS boots from the drive, NOT the Emu. This is when its on smart port mode. Even if I restart, it doesn’t pick up the HD, which boots if its directly plugged into the computer.
And by the way, looking in the Apple IIGS manual, it says the disk drive daisy chain should go 3.5 drive first, smart port(FEMU), and 5.25. If I wanted to use a 5.25 drive, would it still work fine if I plugged in a 5.25 drive, with the FEMU attached?
I might just be doing something wrong too.
Thanks!
*your using, not coursing
That’s right. Apple II systems can normally only boot from drive 1, not drive 2. When you have the Emu in Smartport mode and daisy-chained behind an Apple 3.5 drive, the Emu becomes slot 5, drive 2. You can use it as a data disk with that setup, but the IIGS won’t boot from it.
Ok, thanks! Thats what I thought, but figured Id ask.
I was wondering if the IIcx, since it has a DB-19, can handle the Floppy EMU?
Yes, please see section 7 in the manual. Any Apple computer with an external DB-19 or internal 20-pin floppy disk connector should work.
Steve
I am pretty well sold on your Floppy Emu.
Can I be very basic and ask: will it work with an Apple ][ Europlus? Mine has been sitting quietly watching 16 later Apples/Macs pass it by and it would be great to get it going again if only to allow another generation to play Lemonade Stand and learn Economics from it like my 38 year old did at age 2!
Secondly do I gather it will run on my Mac Plus too? If I can get it out of its carry bag and start it too!
Howabout LC475?
Is ther anyt limit to the size of SD card – I have a 128 GB SD card which I use for storing movies with a compact flash on a USB card reader so I can download stuff for my older Macs from my MBP….?
Other wise getting it and setting it up to amuse me after my upcoming hip op!
Colin
Please see the manual (above) for full details. Yes, those machines are all supported. The LC475 will require an internal connection to its logic board, as described in the manual. For SD cards, smaller capacity cards are preferred and usually give slightly better performance.
Thanks Steve,
Well Friday afternoon has come and I am delighted to say that both my screen and Apple ][ powered up first time after 30+ years!
I know from using them 18 years ago with a 2e I had and foolishly loaned to a neighbours boys – who trashed it – that at least one of the Disk ][ drives isnt set up right but with Floppy Emu I can work without.
It will be interesting to try Visicalc and Supercalc again.
Cleaning to do now….. 30+ year grime on the A2M2010P Green requires attention.
So My order is in the box
Thanks
Hello again,
I just bought a Macintosh IIcx, and thought I give my Model B a try. Floppy mode works no problem, but when in hard disk mode, I can’t boot since I have internal hard drive. How can I make the EMU bootable? This was (of course) never issue with my Mac Plus.
Thanks,
Kristian
Some Macintosh models like the IIcx lack support for HD20-type hard disks. See the “Macintosh Hard Disk” section above for the list of compatible Mac models.
Ah, missed that one, thank you Steve.
If you ever come up with a SCSI-type-thing-a-ma-jigg — I’ll buy it instantly! 🙂

Interesting!
Hi again. Loving your Floppy Emu. However, I have hit a snag. Nothing wrong with the fantastic unit, more the machine I intend to use it with.
In short the only (safe-ish) way to use it in something like a Macintosh Colour Classic is to use it and try and peak at the LCD display, while the casing is off!!!
All that I’d need to fix this is a male to female Floppy ribbon cable (instead of the supplied female to female). Do you think it could be possible to make such a thing and maybe even add it as an option to buy one for us Colour Classic users? Or has someone else thought of this?
Thanks in advance.
Digikey sells 20-pin ribbon cables in many lengths and genders, although I’m not following how a different gender cable would be used. The supplied 20-pin cable (with the detachable 19-pin adapter) is the correct gender to fit the floppy connector on the Color Classic’s logic board. Since the CC doesn’t have an external DB-19 port, this is the only connection option for that machine.
I can only use the female internal floppy cable in the CC which really needs to be extended out. Since that goes deep inside the machine and to the edge connector. Meaning I had to use that cable inside the machine directly to the Emu since it wasn’t the correct gender (female cable supplied with the Emu and female from the edge connector). It’s hard to explain clearly but basically the only way I’d get it to work without an extra cable or gender changer is to plug tthe Emu directly into the cable that was plugged into the internal floppy drive, which gives little slack. That’s why a simple gender changer for either ribbon would work and would be simpler solution.
It just wasn’t a fun experience trying to read the display while barely a couple of inches way from a toasty death by CRT! xD
I might check Digikey out, hopefully postage won’t be too much of a problem. Just thought I’d suggest it anyway! Other Classic/Compact users probably wouldn’t have the problem being their floppy connector is on the mainboard.
The internal ribbon cable is designed to go directly from the computer’s logic board to the Emu. It’s not an extension cable for the pre-existing floppy cable, so there shouldn’t be any need for gender changers unless there’s something unique about the Color Classic that I’m not aware of. Here are some cables like you described, if you want to experiment:

If you’re still stuck, please email me directly and I’ll do my best to help.
I just got my Floppy Emu rev. B – it’s great! I have a potentially stupid question, though. I’m using an Apple IIGS and I have four real drives – two 3.5’s and two 5.25’s. I understand this is normally the max for daisy chaining but the IIGS manual says you *can* daisy chain more drives, they’ll just appear in slot 2, which is the “overflow” slot.
Will this work in any configuration with the Floppy Emu? I briefly tried it last night and it didn’t seem to work, but I’m wondering if it just limits me to using one type of emulation.
Failing that, is there any way to remove one drive (so the Floppy Emu would be the fourth) but still be able to use all the emulation modes while in the daisy chain? Or can you only switch modes back and forth if you’re connected directly to the IIGS as the only drive?
The Floppy Emu can be daisy-chained or be directly connected to the IIGS as the only drive. If daisy chained, you need to observe the drive type ordering rules (described in the manual) as if Floppy Emu were a physical disk drive – 3.5 inch drives before smartport drives before 5.25 inch drives.
Hello, I have an original Macintosh 128k and I’d like to ask you a question: if I use my computer with the Floppy Emu, will I have to put a system diskette in the internal disk drive, or can I emulate having a system diskette plus a software disk, both mounted in the computer? That is, I’d like to know if I will really become “free” of having to use diskettes, or if I will still have to use a system disk always in the Mac internal disk drive. Other option would be to emulate a hard disk, containing both the operating system and all the softwares. But do you know if this original 128k Mac can understand a hard disk emulated by the Floppy Emu? Thanks.
You can boot a 128k from the Emu, but it can emulate only one drive at a time. If you want two, you’d have to use the internal floppy.
That’s right. You can also remove the emulated system disk after booting, and select a different software disk through the Emu’s menus, then the Mac will prompt you when you need to reinsert the original system disk. The Mac 128K doesn’t support the Floppy Emu’s hard disk mode: see “Macintosh Hard Disk” in the description above for the list of Mac models with the necessary hard disk support.
Ok, thanks for your answer!
FANTASTIC!! I just got mine and just loaded up Hard Hat Mack and Lemonade Stand!!
Thanks so much for your quick shipment and awesome product!!!
Hi, i am fixing an old Hunter machine that seems to use powerpc and MAC floppy with unknown programm. i would like to ditch out the floppy drive to gain robustness on this machine because the floppys keep on breaking and the programm is becoming very rare and hard to find.
Is there a way to know if your unit could work. it uses a 3.5 sony floppy MP-F17W-10 which is meant for macs.
thanks for any help.
I’ve never heard of a Hunter machine, sorry.
sorry, some explications are necessary
It is a car alignement machine, manufactured by Hunter. model is K111, it uses a strange powerpc inside the main tower of the machine or maybe an old mac, and uses raw software directly onto the floppy (maybe assembler)
I came to the conclusion that its mac based because of the floppy drive meant for mac’s.
thanks for any guidance to see if the sony floppy can be swaped over your unit, assuming i can read one of the disquette and make an image of it on the SD card.

Hi! I’ve purchased a Floppy Emu Model B just before I found that the default firmware is for Apple II. But I only have a Macintosh Classic. Since I noticed that “use the Apple II firmware only when connected to an Apple II computer. If a Floppy Emu Model A board running the Apple II firmware is connected to a Mac or Lisa, it may cause damage”. Is it OK if I connect Model B running Apple II firmware to my Macintosh Classic for firmware updating? Thanks! 😊
Pat,
That Hunter machine uses standard MFM PC floppy drives. There are many floppy emulators out there that support those drives such as the HxC and Gotek clones.
Yuancun Zhao, that warning only applies to the Model A, which has been discontinued. You can connect the Model B to your Macintosh Classic without worries, and install the Mac-compatible firmware.
Hi, i know at least 2 persons who did try with the gotek and they gave up after 10-12 month worth of work. What could realy go wrong with that ? i have many floppy drive from the same era, only the Sony one works on this machine. could it be that the machine recognise the drive in some way ?
otherwise it completely refuses to work.
thanks,
Hello! I bought it some times ago and it is working great! But there is one point: I did not see new files on the SD card. I copy file to the card on my macbook (mac os x 10.11) but then I connected the emu to apple ii I did not see some of them. It is not depending of format. For example I can see one DSK file and did not see another DSK file. Also PO and IMAGE format. What can be wrong?
Disk image files are displayed in the LCD menu if they’re compatible with the currently selected emulation mode and disk size. For example, 3.5 inch disk images won’t be displayed if the Emu is in 5.25 inch disk mode. The disk image file must also be in a supported format, with the expected file size and signature bytes for that format.
Thank you Steve! It\’s clear! But also i could not see some files what was at the card already. I get the emu with sd card, with software collection.
Hi Roman, I sent you a follow-up email for further support.
I’ve purchased a Floppy Emu Model B awhile back. I just got a chance and fired up the Apple ][. When I select Apple ][ from the menu then 5.25″ it lists no files in the directory listing.
When I load the SD card on my laptop all the files in that same directory list just fine anyone have an idea what I’m doing wrong?
Nice little device!
Marty
You’ll need to install the Apple II-compatible firmware for the Emu, if you haven’t already. Disk image files are displayed in the LCD menu if they’re compatible with the currently selected emulation mode and disk size. For example, 3.5 inch disk images won’t be displayed if the Emu is in 5.25 inch disk mode. The disk image file must also be in a supported format, with the expected file size and signature bytes for that format. Please see the manual for details.
How can I identify my Floppy emulator as a model a or b?
Thanks,
John
Model B uses micro-SD cards and says “Model B” on the bottom of the board.
Is there any way of operating the unit wirelessly or via gui in the same way as “UNISDISK Air”?
The Emu has an LCD screen and interface buttons built directly into the unit, rather than requiring a remote control gui. Please see the instruction manual and the video above for details and examples.
I was hoping for a way to connect it internally and controlling it remotely to keep a clean desktop space with the emulator board out of sight.
Hi, when will these be back in stock? Thanks!
A new batch of Floppy Emu boards is already being made, and I expect to have them available by mid-November or earlier.
I was vague in my prior statement, I apologize. I am interested in buying a few of these for myself and friends. However, I am curious of the usability with SD cards like Verbatim FlashAir and Eyefi Wifi Lan. I am assuming since the cards themselves have the built in LAN and handle sending receiving within themselves, than the only issue is the floppy emu refreshing the display or supporting it without SD card corruption.
I’ve not tried an Eye-fi SD card myself, but yes I think you’re right. Assuming the computer isn’t actively writing to the disk image on the SD card, you should be able to update the contents and then press the Emu’s reset button to reload the directory. This would be equivalent to physically removing and replacing the SD card, which is already possible.
Thanks Steve, I can’t wait to get one for my IIGS!
Does the Floppy emu come with latest firmware already installed or should I update it after receiving?
It comes with the latest Apple II-compatible firmware already installed. For the Mac and Lisa, or for updates, there is a simple firmware update process. See section 4 of the manual for more info.
Got this device, and it works when plugged in, although it won’t read any file unless it is a .DSK file…which I have no clue how to create; nor the manual mention it. Also there is no mention about how to create an emulated disk drive image; since it is not on the manual either; and one of the features of this device is to act like an hard drive.
I have a bunch of files as sit files that I would like to transfer, but I can’t because the mac can’t see them…it would be really appreciated to get at least the barebone info about how to set up the software on the SD card to use this device.
Beside that; excellent work.
Lou, the device is meant to act as a disk drive, so you need disk images on the SD card to make it work.
You can use CyderPress to create disk images for the SD card that can be read on the EMU.
http://a2ciderpress.com
Check out section 6.1 of the manual, which discusses working with disk images, and provides links to web sites where you can download them, as well as examples of software tools that can create/edit disk images. For the Macintosh you’ll primarily be looking at macintoshgarden.org for disk image downloads, and something like HFVExplorer or Mini vMac for creating or editing your own disk images. This applies to both floppy and hard disk images.
The “Vintage Software Collection SD Card” also includes a variety of different disk images for all supported platforms, including floppy and hard disk images, and is intended for people who just want an easy way to get started with some pre-existing disk images.
Stuffit (sit) files aren’t disk images, but are just compressed files (like a zip file). You can use one of the aforementioned tools to put the Stuffit file inside of a disk image, then mount the disk image on your Mac and you’ll see the Stuffit file along with the rest of the disk’s contents. Or you can uncompress the Stuffit file using a Macintosh emulator like Mini vMac, and then copy the uncompressed contents into a disk image for use with the Emu.
68kmla.org is a great resource if you have general questions about Macintosh retrocomputing tools and methods.
You just made my month! I’m now going to actually keep versus sell my Lisa. Thank you for all your hard work putting this together.
What is the correct terminology for the model B extension cable? I am looking to buy a shorter one but need to know the search term.
Is this what you’re looking for? https://www.digikey.com/product-detail/en/assmann-wsw-components/H3CCH-2036G/H3CCH-2036G-ND/999352
Splendid! Thank you
Is there really a company called “Assmann”? Does Kramer work there?
LOL
https://www.digikey.com/en/supplier-centers/a/assmann-wsw-components
I changed emulation mode to “smartport” and now it is stuck on screen with “can’t find smart0.P0” Resetting won’t fix it!
Nevermind, replaced sd card with correct layout. All is good.
Neat product! A good way to keep old computers still usable. Plan to get one at some point.
If and when you have a sale, i will get one! but even if you don’t, i’m still gonna consider getting one! This is an amazing thing because the floppy drives on my Macintosh Classic are failing, and I also want to update both of them to system 7.5.5.
Why is the B alot more expensive than the A? Cant we go back to the cheaper version?
I think you’re looking at the “closeout” price of the Model A, from when the remaining inventory was sold at a big discount. The Model B is the same price as the Model A + Universal Adapter pair that it replaces.
Ah ok. Can we have the ability to switch between different HD20 images?
Yes, that already exists. Just follow the menu prompts on the Emu’s LCD when you’re in hard disk (HD20) mode.
I’ve thousands of WORD and Excel files of my PhD thesis and later papers/articles, of the the period 1988/2000, on my Mac SE, mainly on external iomega Zip Drive Disks, and fewer files are as well stored in compressed state on the Mac SE Hard Disk (and compressing/decompressing functions of the initially used software still works fine as well as WORD and EXCEL, on my Mac SE).
I’ve recently bought your product through my courageous son in the States. Hope to find most or all of my files intact after all these years on the iomega disks. I run my Mac SE, it works fine. I loved this great machine and worked on it for about 12 years before I finally shifted to PC laptops running under Windows mainly due to the exaggerated huge prices that Apple Computers applies to it machines and I cannot afford anymore by the start of the 21st Century after I’ve had purchased my Apple IIgs and Mac SE after 28-26 years ago when I was resident in France and had a much higher income than in Egypt.
There was a problem of an electric spark produced when launching the Mac SE machine with the on/off button, however, the problem was fixed few days ago, i.e. by late Dec 2016, by a genuine local technician in Cairo, Egypt, who has changed the internal switch of the Mac SE on/off button.
Now, everything is ready to connect my Zip drive to see in what condition are my files on the iomega Zip drive disks. I wonder if I can connect your product and the iomega to my Mac SE at the same time before booting the Mac SE. Please, confirm that this type of double connection to the SCSI ports of Mac SE is possible at no risk. Thank you. My final goal it to transfer my file to a recent Mac (of a friend) and then to my recent PC laptop running under windows.
Thanks a lot.

I think your product by all measures is a great one of its category, if not the unique, easy and useful one to use. I’m completely astonished that Apple Computer doesn’t make use of your product to help its old costumers recover their old files stored on vintage Macs to new Macs instead of simply saying to them that their old machines are obsolete/vintage and not covered by any service from Apple worldwide. A great manufacturer can never say such thing or proclaiming he is not responsible of his own old machines, this is a big shame and a unbelievable violent pity action to those who participated in building the wealth of Apple Computer at its early years.
Hopefully, there are great engineers, like you Sir, to save the aged folk, like me, and the World.
Thanks a lot.

The Floppy Emu connects to the 19-pin disk port, not the SCSI port (25 pin). So you could connect both the Emu and your Iomega drive at the same time if you wish.
Wow, I’ve read through ALL the posted feedback (and boy are my arms tired)
Was hoping to find people sharing their pimped out hard disk images. I long to return to the days when my Mac Plus had flying toasters, the “moose” and made a barfing noise when you ejected a disk… I know that if I search carefully, all that can be obtained separately but I have to believe that people have created hard disk images that probably do most if not more of that with games and apps to boot.
Is anyone sharing? (For fun not profit) links?
@ Mark Wolfe, for Macintosh software, most people just download everything they need from Macintosh Garden.
@Techknight, a note about the ability to switch between different HD20 images: I added that feature many months ago in firmware hd20-0.7F-F14.5, but I just discovered that I never updated the link on this page to point to the new firmware. Doh! It’s now updated.
Hey, this thing is amazing. Great job! I have 2 old mac classic’s and I can’t wait to buy this!
I was wondering if you could make an adapter for 8din serial connections
Steve, I’ve got a question, would wireless web control capabilities be possible with something like the Toshiba FlashAir? Similar to the way UNISDISK is? http://tulip-house.ddo.jp/digital/UNISDISKAIR/index.html
Although, having switched to the MicroSD format, I guess if possible, it would only be on the A versions…
Hi, is there a way to format and mount a 1600kb file on the emulator ?
i do have such file for a specific machine, recognised as a “akai 1600kb” at the end its a OS file for a aligner machine
thanks
A WiFi-enabled SD card like the Eye-Fi or Toshiba FlashAir should work, though I’ve never tried it myself.
The Emu is designed specifically for vintage Apple computer disk emulation (Macintosh, Apple II, and Lisa). For industrial equipment, you can probably use a PC-centric floppy disk emulator like HxC Floppy.
Hi Steve,
I am trying to use the EMU floopy drive emulator to install Mac OS 7.5.3 on my Macintosh SE. Somehow the SE does not recognize 1.4 Mb disk images and wants me to reformat to 0.8 Mb. Is there a way to have the SE recognize the 1.4Mb disk images?
Thank you.
Apple introduced 1440K floppy support with the Mac SE FDHD and newer machines. If you have the original Mac SE, it will be limited to using 400K and 800K floppy disks and disk images. You could use the Emu in Hard Disk Mode with your SE, and load OS that way. Or stick with System 7.1, which comes on 800K floppies and which will probably be more usable on an SE anyway.
Hi Steve,
I\’am using the floppy Emu B with my Mac SE/30s. On one of them it\’s working without a problem. On the other one it is only working on the interanl floppy port. On the external port there is no reaction – no power no display. I think it\’s all ok with the Floppy Emu and the problem is on the mainboard? Any idea?
Thanks
Gerhard
If the external floppy port isn’t even getting power, then you have a damaged logic board. You could use a multimeter to trace the connections to the external port, and try to identify what’s broken. A repair service like http://maccaps.com/MacCaps/Repair_Service.html may also be able to help.
Hello, i have a floppy emu version A with universal adapter for my apple iigs, all it was ok but this morning, the 2gs don’t boot on .2mg or .p , only boot with .dsk.
You you known the problem. I already try to put the firmware.
Thank
@fouasson, that might be due to using the wrong emulation mode maybe. Please send me email with the details, and I can help troubleshoot what’s going wrong.
Hi, i’m in Canada, and i’m wondering, how long would it take to reach me? (estimated)
For Canada, 4-5 days shipping time is typical.
Ok thx. I just bought one two days ago and it still says processing. Is there a lineup for people who are ordering these?
There’s no shipping during the weekend. Orders are batched and shipped every few days, and you’ll receive an email confirmation when it ships.
Oh ok. Mine just shipped thanks for telling me!
Loving this Emu, it’s done absolute wonders for my old Macs. However, i’m stuck using the .IMG files that are pre-loaded as there seems to be few (if any) websites that offer the images as direct downloads (or atleast .IMG types that are already loaded). They all seem to be .SIT files which are nothing short of a pain in the bum to extract in Windows. Though I can do it and when you manage to, you are left with the files but still the problem of somehow putting them files onto a floppy image that are the same type that the Emu accepts and are pre-loaded.
The manual is a good start but I am still scratching my head as to how I can make some from the .SIT files you download (Eg. from Macintosh Garden), extracted or not. Is it possible in Windows 7? If so is there a tutorial on how because Google hasn’t given me a proper solution as of yet.
Thanks in advance.
I don’t have a tutorial on Stuffit, sorry. Section 6.1 of the Emu manual has some suggestions for tools you can use to view and edit the contents of disk images, or make new disk images. There’s also some general info here on the use of StuffIt, Macintosh disk images, and their use in emulators that you may find useful: http://www.gryphel.com/c/image/
I try to avoid software that comes in a StuffIt archive, since as you’ve discovered it’s often a pain. Many items on Macintosh Garden are available in several different forms: as a StuffIt archive, as a set of disk images, etc. Check the list of download links and try to find one that’s a disk image. If you must convert a StuffIt archive, do it on a vintage Mac or a Mac emulator like Mini vMac. Uncompressing the stuffit archive on a Windows machine will lose the resource fork and type/creator signatures.
How to use this Floppy EMU to copy files of interest from the HD of Mac SE (that works well up to present day) to a new machine (e.g. Mac desktop/Mac laptop)? I have a wealth of old Word and Excel files that are stored since years on the HD of my old Mac SE (they are in good condition) and I need to transfer these files to a newer Mac (as a preliminary basic step before finally transferring them to a recent Windows laptop). The local Apple Macintosh vendor shops refused to do do that job for me. Thank you for reporting the required steps in some details (if possible without referring me to the EMU Instruction Manual that stays somewhat obscure for me). I understand that I must first insert the SD into the EMU, second I plug the EMU into the rear 19 pin slot of the Mac SE, third I’ll start the Mac SE. At this point, the Mac will turn on, and the EMU will work. What to do next in order to copy the files of interest from the HD of the Mac SE to the SD on the EMU? Is this to be done simply by dragging the files of interest to the SD of the EMU using the Mac SE Finder, or I’ve do something else? My son has bought the EMU complete (including the Floppy Emu Model B, the Frosted Ice Acrylic Case “assembled”, the Vintage Apple Software Collection SD Card, the Full-Size SD Adapter, and the Disk Extension Cable) and send that whole nice package (ready to be used) to me. However, I didn’t use that package yet.
I think it will be clearer once you have the hardware. Yes, you would copy the files to a blank disk image on the SD card. Then you would put the SD card in your Windows laptop, and use HFVExplorer (or one of the other tools described in section 6.1 of the manual) to open the disk image on the SD card and copy out the files. If you need general tutorials on using vintage Mac systems with emulators and disk images, vintage file format conversions, etc, I recommend asking for help in the discussion forums of enthusiast web sites like 68kmla.org and thinkclassic.org.
Does the floppy emu have built-in Macintosh support or do you have to install the firmware after?
Please see step 1 of the quickstart guide included with the hardware, and section 4 of the manual for additional details. There’s one firmware that provides Apple II disk emulation, and a separate one that provides Mac and Lisa disk emulation.
Yesterday I got my Floppy Emu and I’ve got to say, it’s an AMAZING piece of tech, glad to have gotten my hands on one!. And good timing too, the day I got it, my Mac Plus’s internal drive kicked the bucket.
One question though, and it’s about the HD20 emulation mode. I can never seem to get it to work. On bootup, the Macintosh becomes unresponsive and the Emu seems to freeze up as well, though when changing the HD20 disk it works fine. But the Mac still would not boot from it, nor would it be mounted when I had a system disk in the floppy drive, it would just freeze once Finder loaded. I’ve tried updating the firmware on the Emu and have tried multiple different images for the HD20, all of which work in Mini vMac, so it’s not a unreadable disk.
The only thing upgraded to this Plus is 4MB of RAM and the Brainstorm Accelerator, seeing as it seems to work for other Plus users, I would assume the Accelerator has something to do with it, but I do not want to go inside and start removing the whole CPU to check.
Sadly it seems that compact Macintosh (Plus, SE) accelerators don’t play nicely with HD20 disks. If you scroll up in the comments, you’ll see another past report very similar to yours. Perhaps the HD20 routines in the Mac ROM used fixed delays that are affected by the accelerator – just a guess.
@Steve
Ah, alright, guess I’ll be looking into how to disable the accelerator, I’d rather sacrifice performance for HD20 emulation, and hopefully, the uninstall is easy enough if I ever need it again I can.
Any chance you could combine the apple ii and mac modes into one super firmware? I use the device between many machines. Would be really handy! 😉
You may forgive me for my multiple questions before physically using the emu to transfer files from my Mac SE to another computer.
First: Should I use Ciderpress utility to create blank floppy (or blank HD) volume on the SD of the emu (using a Windows machine) before I insert the SD in the emu board that will be connected to the Mac SE, or the SD shipped with the emu board has already such blank volumes installed on it?
Second: I read somewhere in the instructions an alarm on running the emu board under the Apple II mode while the emu is inserted in a Mac machine (since this may damage the emu or the computer). Is this alarm not relevant to a “new emu”, i.e. the “new emu” will run smoothly with the Mac SE as if it has never been run with Apple II machine?
Third: I sincerely hope that you would have some free time to make a YouTube video that will show the users how to transfer files from the Mac to the emu SD. Your previous YouTube videos concentrate on running games or software on the Apple II or APPLE IIGS using the emu board.
Thank you for your reply, and again forgive my basic questions.
1) There are some blank Mac disk images on SD card, and you can use HFV Explorer to create more if desired. Ciderpress is for Apple II disk images, HFV Explorer is for Mac disk images. Please see section 8 of the manual.
2) The warning you’re referring to is specific to the older Model A and does not apply to the Model B. You will need to download and install the alternate Mac firmware, as discussed in the manual.
3) Floppy Emu functions just like a real external disk drive, so you can copy files to/from it just as you would any other disk. If you haven’t yet actually used the hardware, please wait until you have. If you need general tutorials on vintage Mac usage, like how to copy a file, I recommend asking for help in the discussion forums of vintage Macintosh enthusiast web sites like 68kmla.org and thinkclassic.org. I can only provide support specific to the Emu hardware, sorry.
I have an iMac g3 from 2000 running mac os 9 and i also have disk copy installed on it. when I try to make a blank floppy disk image on disk copy, it works and i can transfer games and files onto the blank floppy disk image and then put them on the sd card. However, when i try to load that disk copy image off of the emu, it just says “file not contiguous”. Can you please help me?
Easiest way to fix that is to copy all the files off of the card onto your computer, then erase the card, and copy the files back over there. That will put them in contiguous order. There may have been one in the middle that got deleted and another file went in and partially wrote over that space and then had to go to another area of the card to finish writing, thus it’s not contiguous.
Ok, i will try that, Thanks!
Ok, the problem was the contents of the disk image was in a folder and I needed to take all the programs out of the folder, then put them in the disk image. Sadly I was not able to get mini vmac working on my Macintosh Classic, because it requires 5mb of memory and the Classic only has 4mb. I knew that wasn’t gonna work……
I followed the instructions for the copying the two updating firmware files to the SD on my Windows laptop, and made the correct connection of the emu to the Mac SE and started the emu firmware update.
The first part of the firmware update run smoothly (and the LCD displayed “RESULT: SUCCESS”).
However, the the second part (by holding down the SELECT and PREV buttons, and pressing/releasing the RESET button) didn’t started the AVR microcontroller firmware update.
Instead the display of the LCD became permanently hanging at the display (wrong CPLD 14 ! = $).
I shut down Mac SE, and when launching it again the emu LCD was still hanging at that same wrong message.
I shut down to wait for kind help from your side as I do not know what should I do at this point.
Thanks.
Anonymous, if you give your name and email in the comment form, I can contact you directly to help. Your email isn’t displayed, only I will see it. It sounds like your bootloader isn’t starting when you hold PREV+SELECT and press and release RESET. Did you watch the video demo of the process steps? If it’s easier, you can also start the bootloader by holding PREV+SELECT while you first turn on the computer power, then you won’t have to bother with the RESET button.
Sorry that my message given just above appeared as Anonymous. Normally the concerned fields are filled when I open this emu site, but they disappeared this time when I submitted the previous message. Hope they appear now.
My error in the update was that I didn’t press the RESTART when still holding the PREV+SELECT pressed. Accordingly, I corrected that error and then the second part of the firmware update it worked fine, and to be sure I repeated the two updating parts and both worked fine.
I opened the blank 1440 K blank disk in the Mac folder but Mac said it is not recognized, so I opened the 800 k blank disk and the Mac accepted it.
I changed the name of that disk, and the new name appeared on Mac Finder, and I saved two files to that disk, and the two files appeared inside this disk in the Finder.
I shut down the Mac and get the SD card out from the emu board and inserted it into the Windows laptop.
I used the HFV_Explorer and went to the Mac blank disks. However, I find the 800 K blank disk as it was before doing any file copying to it.
I was all the time believing the blank disk will work as if it is a volume and I’ll find inside it the two copied files.
My ultimate target is to use the emu to get some files from the Mac and copy them into a new Mac via sending the copied files to my son in the USA using my Windows laptop as attached files.
Certainly, there is some gap my understanding of the correct procedure to follow in order to get the files of interest transferred using the emu SD and it blank disks. Am sure you have a solution for that.
Am keen eager to forward a package of deep thanks to Mr. Steve Chamberlin for his “floppy-emu-board” and to thank him much more for the kind help and answers he has delivered to my questions on his bigmesswires.com site about the use of that nice “emu board”. In addition, he was so kind to give several reply messages to my questions via email. It is time to say a great “THANK YOU” to this brilliant engineer who found and shared a great solution for a difficult problem facing the users of vintage Macintosh computers. Finally his kind continuous help and support have resulted in fully transferring two of my old files (20-27 years old) on my Mac SE to my Windows laptop, something which made their conversion to a modern Mac laptop and then to a modern Windows laptop (by my son on a new Mac laptop) possible. These two files now appear perfectly on my Windows laptop with all their original formatting and calculation functions as they were on my old Mac SE. This way, I can continue to make the same work for hundreds of my other old files stored since more than two decades on my Mac SE. For years, I was believing that my old Word and Excel files stored on my old Mac SE are dead and lost for ever as they cannot be recovered in anyway to a modern computer. Now, the solution is out therein. The transfer/conversion process needs patience but it is worth trying. For me, my old files are a real personal treasure as I used my Mac SE for >10 years as it was my unique computer between 1988 and 1998 (after one year of using Apple II-GS that was useless to me since it has never had MS-WORD and MS-Excel software applications). Thank you again Mr. Steve Chamberlin. You are simply great.
the Floppy Emu Deluxe Bundle with Snow White Case is currently out of stock. Will they become available again? I wish to order! 🙂
I’ve temporarily run out the Snow White case, but expect to have more in about a week. The Frosted Ice case is still available.
Ok Thanks! 🙂
I’ve run into a bug with FloppyEmu. I am using it with the Apple IIe PDS card. When I try to connect as a 3.5 800K drive, Apple IIe startup locks up. I’ve tried numerous power cycling and other things. The only thing that works is going back to 5.25 floppy mode. Any ideas?
The Macintosh LC Apple IIe PDS card isn’t officially supported, sorry. See the compatibility table above for details on supported computers and emulation modes. However, the Floppy Emu should function the same with the IIe PDS card as with a regular Apple IIe, in 5.25 inch floppy emulation mode. Smartport hard disk mode may also work, though I’ve never tried it myself (see https://www.youtube.com/watch?v=FRbNz5iL6UI). For 3.5 inch disks, the IIe PDS card requires a Unidisk 3.5 drive (A2M2053), but Floppy Emu emulates the Apple 3.5 Drive (A9M0106) commonly used with the Apple IIgs and IIc+.
A fantastic device and a great contribution to retro-Apple freaks. Highly recommend it. While I miss the click and whir (and scary sounds) of the Disk ][, this is a definite upgrade from them. No more degrading floppy disks and no more finding places to store them.
OMG, take my money!
Thanks for this. I was looking on how to do something similar with Arduino and/or run the disk drive from a PC or Arduino. The $139 bundle should let me do what I need…even copy images to the real FDD on the Apple //e. Worth it in time saved.
Hello, I don’t see several disk images in floppy emu. When I drag and drop new .image file to SD card Macintosh folder, it doesn’t appear in the list neither. How can I make my .image file visible and readible by FDDemu?
Regards, Robert
What type of disk images are they? “.image” could mean a lot of different things. If they are DiskCopy 6.3 images, they won’t work – see the explanation in the instruction manual. The Floppy Emu LCD display will only show disk image files of types that it knows how to use.

Steve
You\’ve done a huge service to all of us, thank you!
Suggestion… On the instructions consider putting a little flow chart in there so customers can more quickly understand if Apple // – good to go … Mac or Lisa – must do a little software assembly…
Also.. I have a use case that needs some expert help. On a 1 or drive Mac.. what is the most effective way to transfer the contents of dozens of 400 and 800k disks to the SD card? Is there a utility on the Vintage Apple SD card that will emulate a hard disk? On a SE II the best I can do is create a new boot floppy and use the blank 800k SD card to copy one disk a time.. then copy the contents on another machine. Of course I have to reboot the Mac along the way.
Please, there must be a better way!
Thanks!
Don
And there is – it helps the read BOTH manuals!
the longer manual http://www.bigmessowires.com/femu-instructions.pdf give specifics on setting up the Floppy EMU to be become not a \”floppy\” but a 20Mb HDD.
Thanks Steve!
Hello,
Is it possible to use the floppy emu for both an Apple IIe and a Macintosh SE without changing the firmware all the time ?
Thank you,
Nicolas
No, the on-board CPLD chip needs to be configured differently for Apple II emulation vs Mac/Lisa emulation, so each requires a different firmware.
Is it possible to order a spare display for the emulator? I received it partially broken probably by exposure of pressure on its top during the transportation.
Regards Robert
Yes, please send me email through the Contact link at the top of the page, and I can help you with the display.
Feature Request: Allow naming the smartport files with “SMART#” as the prefix rather than the whole filename (not counting extension). Use case: in an emulator like Virtual II you can mount “Games.2mg” and “Utilities.2mg”, but when you copy that to your SD card you need to rename them “smart0.2mg” and “smart1.2mg”… and then try and remember which is which if you later try and sync the images. If the files could be named “smart0 – Games.2mg” and “smart1 – Utilities.2mg” that’d be swell. Regardless, keep up the awesome!
Great Website! So easy to navigate, well laid out. You’re the best, thanks for adding the Liron Support! 😀
Hi
Will it work with this
performa 580cd specs
The Apple Macintosh Performa 580CD features a 33 MHz 68LC040 processor, 5 MB or 8 MB of RAM, either a 250 MB or 500 MB hard drive, and a 2X CD-ROM drive in a relatively compact all-in-one case with a 14″ color display.

Is the vTech/Laser Universal Disk Controller (UDC) supported? I have read that the UDC supports smart port devices like the Chinook smart port HD (20mb). I have 3 cards (2 with ASIC and one TTL) and I am willing to lend one card for testing. I have only seem smart port support mentioned together with the ASIC based design.
-Jonas
I don’t have a UDC, but I’ve been told it doesn’t work with Floppy Emu’s smartport mode.
There are a couple of different firmware versions floating around for the Laser UDC. The more recent one should support SmartPort devices.
Just curious: Where is the Rev A manual? I cannot find a link, but the current (Rev B) documentation tells me that’s the appropriate one for my unit.
This is something I scanned myself: https://drive.google.com/open?id=0B5SAWSGa49rLb21GYm5zMFIzYUk
I don’t know if it helps, though
Thanks, but that’s a scan of the UDC manual. I’m looking for the FloppyEmu Rev A manual.

John, please send me an email with the details of what’s happening on your performa. Steveh, is there any specific info you need? I can get a copy of the old manual for you, but I’m traveling now and can’t get it immediately.
Hi, Steve. Nothing specific at the moment, but I realized I do not have the Rev. A manual and would like to get a copy for completeness’ sake. I’d appreciate your making it available when convenient – no hurry.
An older version of the manual with info on both Model A and Model B is at http://www.bigmessowires.com/femu-instructions-old.pdf
Hi Steve,
works great on my “new” SE/30! Thanks. This device is a great help.
Is it possible to remove the SD card without turning off the computer? It would be easier to share some data with my Mac mini.
Jerome, from Bordeaux, France.
Sorry for my silly question :
\”Is it possible to remove the SD card without turning off the computer? It would be easier to share some data with my Mac mini.\”
HotSwap is a built in feature! I
Hello Steve,
I am using FloppyEMU with my Apple IIC in smartport mode.
How can I remove the writeprotection of the \”hard drive\” provided ? (it also shows a locker on the lcd screen)
Thank you,
Nicolas
The smart0.po example disk image is not meant to be writeable. It’s stored in a truncated form where the empty regions of the disk are omitted from the disk image, so there’s no place to store additional data. If you use one of the other smartport example files, or create a new one with Ciderpress or one of the other tools described in the manual, then you can read and write to the disk.
Thank you Steve. I got the point.
Do you know where I can get the largest possible blank image for Apple iic (Prodos, not GSOS) ?
Thanks again for the fast response 🙂
ProDOS supports disks up to 32MB, and Cidepress can make a blank disk image. See section 8.3 in the manual for info on working with disk images.
I have a little problem with my floppy emu for the Macintosh. I am not able to access the system folder to start the finder or change the default settings for the mouse speed. That makes it really difficult to play games which require a mouse. Never the less, i am able to access the games folder and start the games. What could be wrong?
https://youtu.be/4tKkQjqaKwU
Another problem is, after starting the HD 20 mode does the Emu display show:
“Next: Set Startup Disk”
What does this mean and how do I set up a startup disk?
> I am not able to access the system folder to start the finder or change the default settings for the mouse speed.
Mouse speed in the classic Macintosh OS is set using the General or Mouse control panel, which you’ll find in the Apple menu.
> “Next: Set Startup Disk” What does this mean and how do I set up a startup disk?
Press the NEXT button on the Emu board, to select a startup disk image from the menu.
> I am not able to access the system folder to start the finder or change the default settings for the mouse speed.
“Mouse speed in the classic Macintosh OS is set using the General or Mouse control panel, which you’ll find in the Apple menu.”
My control panel in the apple menu shows only: Desktop Pattern, Insert Point Blinking, Menu Blinking, Time, Speaker Volume and Ram Cache. There is no Mouse Speed Adjustment. Finder Version 6.1.8, System 6.0.8 I am using the HD Emulation and the software from your sd card.
> “Next: Set Startup Disk” What does this mean and how do I set up a startup disk?
“Press the NEXT button on the Emu board, to select a startup disk image from the menu.”
Why do I need to select a startup disk image, when the Mac has already booted up? Whould that startup disk be used for the next boot up?
If a particular disk image doesn’t have the Mouse control panel in its System folder, then you won’t see it listed. You can copy it from another System 6 disk into your disk image’s System folder. The Vintage Apple Software Collection SD card has a copy of the full System 6.0.8 installer, which includes all the extras and accessories. Details on usage of Classic Mac OS control panels is unfortunately outside the scope of the tech support I can give, but 68kmla.org is a good resource for general Classic Mac OS-related questions.
The NEXT button is used to select a disk image for Mac HD20 (hard disk) mode. The selected image will be used after the next reboot.
Hi Steve,
I have two questions for you.
1) Can this run protected disk files, or is it like other solutions not able to?
2) What is the difference (in essence) between this solution and the CFFA 3000 adapter card? Anything this would bring to the table the other doesn’t or viceversa?
Thanks!!
Floppy Emu isn’t a cracking tool and doesn’t have any special anti-copy-protection features, but you’ll find most common Apple II software is already available in a cracked version. You’ll have to draw your own conclusions about the the CFFA3000, but it’s a different kind of device (internal card vs external disk replacement, etc).
Hi again, thanks for replying!
I didn’t mean as a hacking/copy removal tool, what I meant was some disks came with copy protection, and a “normal” disk drive reads them just fine, so I wanted to know if this also reads those fine (images of disks that are not cracked but have protection) or if it also cannot like seceral other disk drive replacement solutions for different machines.
Also after reading some I guess this also has the pro that you can use it on computers that have external port only for drives and you cannot use a card in a slot
I recently got a floppy emu and its pretty great! For transferring all 5.25 inch disk images for apple ii. The problem is that I can’t seem to use any 3.5 inch images or hard disk images. I already updated the firmware just wondering if there is another solution. I Have a iigs and I kinda need 3.5 files for that. Thanks for any help I can get.
Have you read the Emulation Modes section in the manual? https://www.bigmessowires.com/femu-instructions.pdf You can use the Contact link at the top-right of this page for customer support.
HI!
Question: When will your “Floppy Emu Deluxe Bundle” be available again?
I want to use it for my Apple IIc as well as for my Mac LC.
Thanks for an answer.
Hi. Just got my Floppy Emu. Love it.
However, after having used it without any glitches on a SE with System 6, I’m stuck in an endless loop when I try to use it on my Plus w/System 7.1.
When I reset the Floppy Emu, It keeps asking me to select a startup disk. Then, it asks me to reboot my Mac.
I don’t want to use an image as a startup disk. The Mac is already booted, I just want to select an image to access its content.
Thank you for your help!
It sounds like you’re using HD20 hard disk mode. You should never need to reset the Emu during normal use, except when changing emulation modes or the hard disk image. Can you take a video of what you’re seeing and send it to me using the Contact link at the top-right of this page?
Hi, is this item still available somewhere for buying?
I hope to have more Floppy Emus available by early February. There’s a note about this near the top of the web page. You’ll see it updated there when new stock is available.
Thanks SO MUCH for the update. Page bookmarked and I will visit periodically in the next days.
Cheers!
I am looking at using the Floppy Emu to connect to a Mac SE (not the SE/30 model). I don’t have a Windows PC, but have many generations of Macs available. Can I connect the SD card up to a Mac running macOS Sierra to access the SD card to read and write files and then connect back up to the Mac SE? My primary goal is to extract some files stored on the Mac SE, but I’d also like to try and put some new software on the Mac SE, as well. This Mac SE has the 800K floppy drive, so it doesn’t work with the 1.4MB HD disks.
Please see section 8.3 of the manual for info on working with disk images. http://www.bigmessowires.com/femu-instructions.pdf When viewed on a modern Mac or PC system, the SD card will appear to contain disk images, not individual vintage-format files.
Wow, that was fast… any estimates for the next batch?
Or is the “package” out of stock because it’s just the cases that are not available? total cost is the same than buying individual anyway, right?
Yes the acrylic case is out of stock for a few weeks, sorry. The Floppy Emu board is still available.
Can I order to secure my board and add the case when It’s available?
There are enough boards to last for the next few months at least. You can order a board now and buy the case separately later, or just wait until they’re both ready.
Thanks Steve!
Just got the EMU today for my Apple llc with 255 Rom. Dosen’t Boot up, I know I’m probably doin something wrong but I can’t find the Answer.
Hi, Steve. I will be in the USA (New York) from Feb 20th to 26th. is there any chance that the case (and the bundle) will be available by then?
Thanks!
Fabricio it’s possible, but I don’t know the exact date – it will depend on the speed of manufacturing and shipping.
More acrylic cases are in stock now.
\o/ Whoa!! Thank you, Steve!! Order just placed, #2277!
Hi Steve, great product. I was using it for a month with Apple //c and Apple //e but now want to move to GS. I have 3,5\” A9M0106 drive – if I understand correctly – FloppyEMU B will work thru daisy chain after floppy drive but not directly? I have both ROM1 and ROM3 Apple IIGS.
For information on Apple II daisy chaining, please see section 6.1. the manual. Floppy Emu can be connected directly to an Apple IIGS or chained after another drive. It does not have a daisy-chain output.
Great little device.
Two features that are screaming out to be implemented:
1. The ability to mount more than one disk image at a time – this might require an extra wire in 5.25″ disk mode while being used in older style Disk II control cards, but not on the DB-19 controllers or smart ports
2. The ability to read / write 800K 3.5″ floppy disk images while in smart-port mode – this could increase the speed immensely.
Otherwise I love this device.
Dual disk emulation would be very nice for some Apple IIs, but isn’t possible with the current design, nor with the Macintosh or Lisa. Unidisk 3.5 mode (in the latest firmware) supports 800K 3.5 inch disk images on the Smartport.
I ordered your deluxe model B kit for my original 512k Mac and I’m struggling to get anything to load from the emu. It just gives an error message when trying to load any 400k program via the external floppy port. So far I have a hundred and fifty dollar paper weight with a cool clear case… Please help!
Michael, if you have original 512k Mac it should work but if I remember correctly original one has no support for 800k drive so you can only use single density 400k so try by using MFS formatted images first. Have you choosen emu mode correctly? My 512k Mac works flawlessly with Floppy Emu.
@Michael, Marcin is correct about the Mac 512K. Please send me full details via the Contact page if you’re still having troubles, and I’ll be glad to help.
It’s a must-have for owners of computers this item can be connected to. Thank you very much for developing this piece of hardware.
Me, using it on an Apple IIgs to moount floppy images created some years ago off of my 5.25″ 8-bit and 3.5″ 16-bit collection.
Also working with the Smartport functionality found in the Floppy Emu, using disk images created off of Apple II CD ROMs found in my collection. These CD ROMs often came with a number of partitions (up to 6 partitions usually), like “Generous Efforts of Many” and “Golden Orchard”. I ended up creating images of each partition separately to add it as smart|x].po…
Found a hint over at Bondihacks just to rename the .hdv extension to .po to get it recogniced by Floppy Emu. 😉
Regarding CD ROM use with Floppy Emu, it’s like you’ve added a SCSI CD ROM or Zip Drive to your computer.
Would like to see removable smartport media support mimicking a CD ROM or Zip Drive by the FloppyEmu, but as a non-hardware developer, I’ve no idea if it is possible at all. Keep up the good work on Floppy Emu!
Thanks to you both, Steve and Marcin for such a quick response. I know and understand the original Mac 512k’s only supported 400k disks. Wich it will not load. My goal was to play the original Dark Castle game on this very same machine and relive my childhood. I will get back on it this weekend and send full details. Thanks again for the response and support!
Michael, it’s possible. You need emulator like vmac, and you need to convert image from HFS to MFS as disk image. If it sounds to complicated I may try tommorow.
Michael, I have checked – you need to find 2x400k distribution of Dark Castle for Macintosh 512k, the original one was 800k floppy and it won’t work on 512k and even 512kE due to both – 800k floppy and RAM amount. If I will find it, Iwill ping you here. Cheers.
Awesome Steve, I see the cases have come in and ordeded mine! 🙂 Hope it arrives in time for my trip. Do you know *on average* (I know it can vary) how long it usually takes to get to somewhere like TX? Also, doesn’t matter now as there is only one option, but am I crazy or did there used to be other options for the case color? Cheers!
Yes we’ve been through several variations of case colors and designs! Shipping terms are explained on the store page. For this package I’d guess delivery sometime between March 31 and April 3.
Great, if that’s the case it will be before I leave Tx and on to my next destination. Thanks for this awesome prduct, looking forward to using it! :]
Thanks !
I’m in France and got my Disk Emu in 4 days…
The Disk Emu is great, straight forward and practical ! I only wish the cable ribbon connected to the Disk II Interface would be facing the other side of the connecter (not to be stuck between card and connector) like it is for regular drives. But there’s maybe a good reason why it is this way …
Now of course all this would even get better with a Liron disk controller !!!
Any release date in mind ?
Also what is the biggest SD Card capacity usable ?
Many thanks again for this great product and the very fast expedition !
Xavier
Thanks, Steve! Shipping was super fast and I already have it with me! Will still have to wait until I return home to test it, but it’s with me 😀
I bought the Floppy Emu after fighting with old noisy SCSI drives and failing 800MB floppies, but trouble no more! I can enjoy my retro Mac Plus reliably in complete in silence. Emulating the HD20 hard drive emulation is fantastic and is very quick, almost as fast as a hard drive.
What a great job on this product, working perfectly so far.
I’m now in the middle of buying an Apple IIe so I can play with that using my Floppy Emu.
Hi Steve, after doing firmware update I guess it-s ok to delete the files from the root, right?
Also, if you want to switch computer models you have to re-flash every time?
Thanks!
Yes, that’s correct.
So awesome. Love it!
I just received my Floppy Emu and acrylic case. This being my first ever Apple setup (a IIGS) I struggled a little with using the disk images, but I think I have figured file extensions, etc, now.
However, am I the only one struggling with the acrylic case?
Assembling it was straight forward, but I have several problems when the FE is installed inside:
– The manual warns about problems if the lower, right screw is too tight, but in my case I have to loosen it so much it’s really serving no purpose at all. If I tighten it even a fraction, the Forward button gets stuck and won’t budge.
– However, when it’s loose enough for the Forward button to move freely, I have issues with this and the Select extenders both slipping off the buttons and getting stuck. Also, now the side panel around the SD card is no longer held in place all that well.
– Also, even when the buttons appear to work (for a while), I get other issues, like pressing the Select button often giving me a Forward button press instead.
– Lastly, a couple of times the device has hung, and/or the screen has become garbled while using it inside the case.
Right now I have removed the case, and the FE works great outside it. It’s apparent that everything stems from pressure, or lack there of, from the case. My problem is that I haven’t been able to figure out how to set the screws exactly right. Tolerances seem very tight.
Any suggestions will be greatly appreciated.
It sounds like maybe the top panel is bowed – is the board seated fully and flat on the bottom? If the side panel is too loose when the screw is untightened, try adding a piece of tape inside the case to hold the right side piece to the front or back piece. If you’re still having trouble or want to return the case, please send me a note at http://www.bigmessowires.com/contact/
Thanks, Steve.
I was thinking about securing everything with superglue, but I need to get everything working reliably first.
I’ll check for signs of warping, and do another assembly to see if I made any mistakes.
Steve,
I just updated the CPLD and AVR software on my Rev B. One suggestion: in the text file that comes along with the other two files, you may want to add a “what happens after the update” list, such as the LCD brightness resetting to default. It has been awhile since I had to adjust mine, so it took me a bit to dig through the PDF and find the procedure. Seeing you already have the text file in the archive, might as well put it in there. Not sure if the disk mode changes as well, but if it does reset after an update, I’d add that as well.
I’ve recently acquired a Macintosh Plus w/o an internal floppy drive. It’s been difficult to find an original Sony MP-F51W-23 800K floppy drive, while the Sony MP-F75W-01G 1.44MB models are much easier (and cheaper) to come by.
Is anywhere aware of whether the 1.44MB model will work in the Mac Plus? I know the Plus would still only be able to use 800K floppys, but that’s quite alright. Any info is much appreciated.
Not sure – I think it might work for 800K disks. Try asking on 68kmla.org, somebody there has probably tried it before.
there was ROM update for Macintosh Plus to work with Superdrive, otherwise it won’t work even on external drive with HD floppies. So 400/800k will work only. Same for 512k – only enhenced (so probably ‘e’ education) models will work with 800k floppies, as ROM needs to include procedures for working with another density/capacity drives.
Hi.
Just a follow up to my earlier posts about problems with the acrylic case.
After careful reassembly, it now seems to work as it should, i.e. the issue was –> me <–
(Not sure what I did differently this time around, though)
Anyway, thanks to Steve for his support emails.
Enjoying the Floppy Emu so far.
The only problem I’m having is with the system disks in the vintage software collection. They won’t mount on my Macintosh Plus and I get “FATAL ERROR SD read error” every time I try. Other disks mount fine.
I tried the disk images from the Mini vMac site and got the same results.
Are there any issues with updating the firmware on a regular basis to switch between Mac and Apple II? If there is a finite number of update cycles the firmware memory can tolerate or if there is risk in failed updates bricking the unit, I am wondering if it would be better to have two separate emus. Have any started to have trouble taking firmware updates after a number of cycles.
I wouldn’t worry. There’s no risk of bricking, as the firmware bootloader is in a protected memory region. The firmware memory is rated for a minimum of 10000 erase cycles, so you’re very unlikely to reach that in the device’s lifetime (or your lifetime). But you might be interested in this: http://dangerousprototypes.com/blog/2010/05/25/prototype-flash_destroyer/
Hi,
I am running GSOS with the Floppy Emu and everything is just fine except that the copy and paste commands are disabled. Do you think this problem is related to some misconfiguration of the floppy emu or is something else?
Ignore my previous message I’ve found the problem – I needed a Finder extra for that.
Finder Extra – What one?
ClipCopyPlus you can find it in this image under Finder.Extras http://www.whatisthe2gs.apple2.org.za/files/System_Addons.zip
Thanks, will take a look. 🙂
Hi Steve,
I received the Floppy emu B & the Vintage Apple Software Collection SD Card on May 28 (3 weeks after my order).
I tested the device on a Mac Se, Mac SE30, and an Apple IIGS using the floppy mode. Everything is all right.
I am trying the Hard disk mode in a few days & hope it will be ok, too.
Once again thanks for your device.
Claudio
I got the Floppy Emu, and had trouble with many games images downloaded off the Internet not working with the Apple IIe. The trouble was not just images I had, but also the included Up n Down image included on the SD card of Apple software. What I found out was that I had plugged the floppy controller into slot 7. Apparently, the floppy controller needs to be plugged into slot 6 in order to work correctly. I wanted to share this here, in case anyone else runs into a similar issue.
Being new to Apple II collecting, this took me a little time to troubleshoot. Hopefully this info can help other out. 🙂 Happy gaming!
Yes, at its time it was known that the 5 1/4″ usually belongs to Slot 6, and the 3,5″ belongs to Slot 5. Apparently, the controller cards could be technically plugged into *any* slot, but works best with these numbers given.
Anyone tried using the model B with a 655-0101 controller? My IIe has a DuoDisk that doesn’t seem to work anymore. When I connect the Floopy EMO to my I/O controller card (via the 19pin adapter), it gets power just fine, but doesn’t let me boot to any of the media on the SD card. Thanks!
My first Mac (512K) got the MacPlus upgrade way back when, and the old beast still works. I have old single density diskettes that it can read and write, but no way to transfer their contents over to my Mac Mini that has a Basilisk II emulator running System 8. Am I reading correctly that with your Floppy Emu Deluxe Bundle, I can plug it into the external floppy port on my MacPlus and copy diskettes from the internal disk to the SD card on the Floppy Emu, then plug that into my Mac Mini and have the Basilisk emulation of System 8 read it?
Yes, that’s it.

I got my Floppy Emu a few days ago and it’s pretty cool but seems to have a weird (at least to me) problem. After a few minutes of running, the display gets all crazy. Garbled display, all black then all blank. Anything that causes it to re-draw the screen, like ejecting a floppy image, makes it look good again but it quickly messes up again.
It’s actually working fine all this time but the more messed up the display gets, the harder it becomes to use.
It seems to work fine at first but as it warms up, it gets worse.
Weirdly, it looks like it works perfectly when plugged into an internal port but goes mental when plugged into the external.
Has anyone seen something like this?
Yes, this sounds like the LCD mount may be loose, causing erratic behavior. Please see section 3.3 of the instruction manual for some tips that should help. I’ve replied directly to your email, if you need more help.
I’ve got the same garbled screen problem. I’ve also been getting SD card read errors every so often. I’ll try the mounting tips in the manual as and report back.
I busted out my model A the other day and got my mac plus (mentioned earlier in this page) back up and running. The CMS hard drive stopped working (RIP) so the EMU has become a Hard Drive Emulator only for the Plus. The thing is, no matter what I do, I can only get it to boot from a 30 MB HD20 image. When I make a large 2GB image and copy the contents of the computer to it, the mac will not see it. Is there something I need to “bless” it? In theory this should work…..
update (if anyone cares!), I discovered that app vMac and \”booted\” my 30mb disk image on my real mac, mounted my 2GB disk image, renamed it to the same disk name that my 30mb drive is called and copied the files in vmac. the 2GB dsk file booted! It seems that using HFV explorer to copy system files does not bring over all that the plus needs to boot I guess. Keeping the files in Mac os does the trick!
De ar sirs, do you deliver it in Brasil? Thanks
Yes, there are many Floppy Emu customers in Brazil. International shipments are sent by USPS First Class Package International service. However, typical shipping times to Brazil are very slow – as long as two or three months. If you need it faster, you may wish to use a reshipping service such as reship.com.
I downloaded the ‘femu-instructions.pdf’ above and read the ‘Contrast Fluctuations, Garbage on Screen, Missing Lines, or Blank Screen’ instructions and made absolutely sure those 4 metal tabs were locked-in and positioned correctly, but I still have garbage on my screen most of the time (not all, but most of the time) and sometimes the screen just goes blank. The root problem seems to be the design in that those soldered contact points aren’t making good contact with the PCB pads. If they were making great contact, I wouldn’t have these screen issues. Any advice on how to solve this problem once and for all? (Fiddling with those 4 tabs doesn’t work for me.) Thanks.
If it’s not working correctly and none of the suggested remedies help, please use the “Contact” link above to get in touch and request a warranty replacement.
I know, but returning it would cost me 2-way international shipping which I am desperately trying to avoid. Because you have a dedicated page in the FloppyEMU manual that talks about the problem with clear photos, it’s rather obvious the problem affects more than just a few select people. As such, by posting here, I was hoping that other users of the product might have come up with a DIY repair solution that I could try. If you have a potential solution I could try myself, Steve, I look forward to hearing it. If not, I’m open to hearing suggestions from other users of the FloppyEMU. Thanks!
I had problems with mine as documented above and a replacement was sent out that works well.
After reading the most recent comments I went back to my old display to have another look.
Under the microscope it looked like some of the solder joints that connect the headers to the display board might have cracked a little.
I touched them up with the iron and a little extra solder. I then put it back together and tested it out for a couple of hours.
So far, so good. Before it would sketch out after 5 or 10 minutes.
It might be a coincidence but….????
Thank you for sharing your experience, Mikol. I had thought about refreshing the solder myself, but I didn’t want to accidentally kill the screen entirely by doing that. Your experience indicates that it actually may improve or completely fix the situation. I’ll give that a try. It would be much cheaper for me to do that than pay for two-way international shipping.
Customers aren’t responsible for shipping costs for warranty repairs, and for hardware that’s no longer under warranty, replacement LCDs can be found on eBay for a few dollars. Each LCD is inspected and hand-adjusted prior to sale. The sensitive spot is the pressure-fit connector between the LCD module and the square red board. It has 8 tiny pins that flex slightly as they’re pushed against the contacts on the red board. If any pins are misaligned or are taller than others, it can cause intermittent display errors or a blank display. Tightening the four metal tabs puts more pressure on the pins and helps get a more reliable contact.
Steve and fellow FloppyEMU lovers! I am pleased to report that after applying fresh solder to the PCB pads that drive the LCD, ensuring to make each new solder blob a tad taller than the stock solder blobs, my FloppyEMU display is now perfect. Sadly, my fix wasn’t in time for my new video where I show off the FloppyEMU a little bit, but at least the display problem is fixed now. I hope this advice can help other FloppyEMU users in my shoes. BTW, you can see the FloppyEMU at about the midway point in my video here: https://youtu.be/hiN7mP9iQxA?t=1581
Cool, thanks for the tip!
Steve, skund like great advice, mine does that too. Could you give a little more detail on how/where to add more soler?
Sorry, I meant James
Very cool,
that was the next thing I was going to try but haven’t done it yet as it’s been working very well lately.
And yeah, these are all over eBay for almost nothing. I didn’t realise that they we so common. Good to know for future. I just searched for Nokia LCD and a bunch popped up.
Again, thanks for building this, I love it.
Walter, Mikol (and everyone else with the LCD problem),
Scroll up on this page and click the “PDF” text link to the right of “Instruction Manual” in the Documentation box, then scroll to page 6 (which sadly has no page numbers) and look for “Contrast Fluctuations, Garbage on Screen…” That shows you the LCD module and how the 4 little tabs should look on back. That module connects to the main PCB with 2 connectors and is easily removed.
To apply fresh solder, you will need needle-nose pliers to bend those 4 metal tabs you see in the photo in the Instruction Manual in such a way that you can pull off the LCD from that little PCB. It will then be obvious where the PCB pads are that you need to resolder. Before you resolder, obviously, you need a copper desoldering wick to remove the factory solder, then apply fresh solder in the shape of a little mountain on each pad. I suggest using very thin solder (most solder is a bit too thick, and you might apply too much using thick solder).
I took before/after photos: https://www.icloud.com/sharedalbum/#B0wGFssfGGrdABZ
Is there a reason why these things are up over 100 bucks now? I was thinking about getting a 2nd one until I saw the price and said nope.
I’m sorry you don’t find it’s a good value. The price of the Model B hasn’t increased and is the same as it’s always been, and there’s currently a Get 10 Give 10 promotion on the Deluxe Bundle – see the front page for details. In short, the hardware is priced at where it’s worth my while to continue making and supporting it. As you found with your Mac Portable RAM product, these niche designs require major time and effort.
In answer to Mike,
I bought the whole kit and found it well worth it given what each of these programs that are loaded were charged for back in the day.
Then have the ability to store more? Naa, well worth the money to me.
Steve,
I apologize if the answer is somewhere in the docs, I just haven’t find it.
Is it possible to do a simple a copy of the micro-sd to archive?
Thanks
You can copy the the Vintage Software Collection SD card on any modern PC, Mac, or Linux computer with an SD slot. It’s just a standard Windows-formatted (FAT32) volume.
Awesome thanks.
Works great!!
from time to time i have few glitches
the display shows nothing and it don’t respond to the clicks..
After few boots it’s become stabale again ///
any similar symptoms for you guys ?
That doesn’t sound like normal behavior. Please use the “Contact” link at upper-right and I can help you with troubleshooting.
@rami shaked, “nothing on the display” sounds like my problem. The backlight worked great, but the LCD was glitchy and sometimes displayed nothing at all. Fixing the little metal mounts as directed in the documentation did NOT solve my problem, but applying fresh solder did (see my earlier post about that). As to buttons not working, that too is covered in the documentation, specifically the button in the lower right corner. Loosening the nut isn’t ideal, so what I did was take a box cutter (razor blade knife) and cut out a little of the part of the transparent button extended piece that goes over the button in the lower right, that worked great to solve the problems I was having on that button, so it might help you as well.
James thanks,
i’m not sure that the buutons are not working because i cant see anything on the screen, so i’ll wait to solve the presentation problem first.
i’m not a soldering man so i’m afraid to mess it, i’ll wait for Steve response (i emailed him with a movie and hope he will find a way to helkp me).
right now most of the time it’s not working, from time to time it’s shows the text and after one or two boots it’s gonbe again.
It looks like i solved it with Steve great advices now it’s working like charm. wonderful product with goos dervice 👏
I probably discovered the same problem as rami. If you place the emu into a case, you can’t tighten the screws too much. The stems for the buttons are a bit too long. If you turn the emu on, and the screen immediately shuts off, the problem is that the top lid is pushing down on the stems, which then push down on the buttons. I had to loosen the nuts to give the stems some room. The permanent fix is to stick a piece of tape between the top lid and the walls, and that’ll avoid the lid from pushing down too much.
I ended up 3d printing a case for mine. It won’t win any design awards but it works well. I’d post a picture but I don’t see any means of doing so here.
Hi Steve, do you have these in stock, and are you taking into consideration the latest comments to add just a bit more solder to the LCD part to avoid losing image?
Yes they’re in stock – the “add to cart” button above and the BMOW store page reflect the current stock status. I don’t do back orders, so if it’s listed as available for purchase, that means it’s in stock. I don’t recommend resoldering but I’m glad it’s helped a few people. Each LCD is tested and hand-adjusted prior to sale to ensure it’s working well. The hardware is covered by a one year warranty, should you run into any problems down the road.
Hi Steve,
thanks for the great accomplishment with the emulator: I wonder how much competence and skills you have.
Anyhow, I got some issues to report;
(I’m using a Mac SE HDFD)
– the display often shows no text, it’s “blank” but apparently, it’s working, I can blindly scroll the images and select them. The issues can sometimes go away by resetting it. Fuzzy text sometimes appears, BTW: I got the plastic case.
– when installing System 7 in general when I need a series of floppies to be inserted in sequence, it works just fine, unless … I do not insert the floppy for a while (I can not tell precisely how long, but I’d say 10 minutes or so). Blank screen and the Mac SE debug screen blinks fast.
– using the HD20 mode, the emulators asks me to restart the Mac to boot from the virtual HD. But this is not what I want, I’d like to “mount” the HD, booting from the internal SCSI HD. Is this mode supported?
thanks
all the best

Sorry you’re having trouble, Peter. For 1-on-1 customer support of individual issues, please get in touch directly using the “contact” link at upper-right, and I’ll do my best to help.
Hi Steve,
Sorry to disturbe you, but I have a problem when update the firmware: when I finish the Step1 (and the “WRONG CPLD:20!=6” displayed) and continue to Step2, that’s nothing happened even I holding the SELECT and PREV buttons and press/release the RESET button. the wrong messenger is still there. I’d tried again and again, the Step1 was successed everytime but the Step2 wasn’t.
I’d read the README file carefully and sure no wrong opeation. Can you analyze it for me? Thanks very much!

How big of an SD Card does the FloppyEmu Model B support? SHXC? SDHC only? The reason I’m asking is because now that .WOZ support is in Beta, I’m seriously thinking of much larger SDCards for mine, and wanted to know what the max size supported actually is. Yes, I’m expecting a ton of .WOZ images, eventually to be out there, plus my own personal ones, when I get my own AppleSauce device 😉 Thanks for this device BTW, it’s super handy, as you well know 😉
Smaller capacity cards perform better for writing data, so I wouldn’t recommend going with a huge card. A 32 GB SDHC card is large enough to hold hundreds of thousands of Apple II disk images. I’m not sure if the SD library in the firmware can handle SHXC cards, but if somebody has one and wants to try it, please let me know what you learn.
I ended up trying it (SDXC) before you responded.
So the 1st 16gb Class 10 SD card (Samsung EVO) got destroyed in about 3 weeks of use in the device (the power surge thing I suspect, since I was quite often removing and inserting the card as I was tinkering with it and learning how to use it etc. I now have a label on the FloppyEmu to remind me to only insert and remove the SD card when it’s not powered at all.).
The 2nd 16GB card (the 2nd of the same type as above- I bought 2 at the time) has worked great, but I haven’t been removing and inserting it all that often since I’ve now got it setup and don’t do that activity much anymore.
So when I wrote the above question, that card was in it. (just a bit too small, as you pointed out above). So I ended up with a 64gb SDXC card (Lithium-Ion battery expansion in a smartphone- and the SD card needed a new home) and I had it on hand to try. So I did, and it works great and no more full card! (for the record it’s a 64gb Samsung EVO Class 10 and UHS-1 micro SD card)
