- Connects to external (DB-19 D-SUB) or internal (20 pin ribbon header) floppy drive connector
- Supports all major Apple disk image file types
Macintosh Floppy – Supports 400K, 800K, and 1.4MB floppy disk images, in raw .dsk or Disk Copy 4.2 format. Disk image files are the same format as those used with popular software-based Mac emulators like Mini vMac. Compatible with the original Mac 128K through the Mac II series and Power Mac.
Macintosh Hard Disk – HD20 hard disk emulation is compatible with the Macintosh 512K, 512Ke, Plus, SE (not SE/30), Classic, Classic II, Portable, IIci, IIsi, or LC I. Supports bootable hard disk images up to 2GB. Disk image file is compatible with popular software-based Mac emulators.
Lisa Floppy – Emulates 400K and 800K floppy disks on the Lisa 2/5 and 2/10. Boot or mount native Lisa Office System disk images in Disk Copy 4.2 format, or use Macintosh disk images within the MacWorks environment.
Apple II Hard Disk – Emulates up to four simultaneous Smartport hard disks, each up to 32 MB (when formatted as ProDOS) or 2 GB (when formatted as HFS). Smartport disks are compatible with the Apple IIgs, Apple IIc (ROM version 0 or newer), and Apple IIc+.
Apple II Floppy – Emulates 5.25 inch 140K floppy disks on any Apple II series system, as well as 3.5 inch 800K floppies on the Apple IIgs and Apple IIc+. Disk image files may be in .DSK, .DO, .PO, .NIB, or .2MG formats. Disk images are compatible with common Apple II emulation tools such as AppleWin and Ciderpress.
Connects to the built-in 19-pin disk connector on the IIgs and IIc, or to the disk controller card on the Apple II, II+, and IIe. Compatible with the Disk 5.25 Controller Card with 19-pin connector, and the classic Disk II Controller Card with two 20-pin connectors. See the instruction manual for details on drive numbering and boot priority.

- 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, or .2MG format, 800K floppy disk images in the same formats as well as 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 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 .NIB disk images, but this isn’t a 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.
Please see the Floppy Emu manual for complete details and usage instructions.
Macintosh and Lisa
- Mac Floppy + Hard Disk and Lisa Floppy firmware, for all models: hd20-0.7G-F14.5
- Apple II firmware, for Floppy Emu Model B: apple-ii-0.1R-F8
- Apple II firmware, for Floppy Emu Model A: apple-ii-0.1R-F6
IMPORTANT – For Model A, 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.
