A floppy disk drive emulator for Macintosh computers, using an SD memory card and custom hardware to replace a 3.5″ disk drive and floppy disk.
How can you deal with signals that might be inputs or might be outputs, in a way that’s safe and won’t damage sensitive electronics? In my last post I described three different types of Apple II family floppy drives. Since…
I’ve begun looking into the possibility of Apple II disk emulation with the existing Floppy Emu hardware. The recent research project into Lisa floppy emulation turned out well, so why not do it again with another vintage Apple computer? A…
I’ve merged the Lisa floppy emulation functions into the latest Mac version firmware, to create a super universal firmware! it’s a single firmware for Floppy Emu with support for Mac and Lisa, floppy and HD20, raw disk images and Disk…
Lisa floppy drive emulation with Floppy Emu is a success! Begone, evil rotational disk drives, with your failure-prone gummed-up mechanisms. The age of SD card Lisa floppy emulation is here! After a lot of tinkering, it’s now working on both…
Watch this video on YouTube I’ve been crawling slowly closer to a working floppy emulator for the Apple Lisa, using my existing Floppy Emu hardware. I’ve now got something that’s broadly usable for emulation of Macintosh disks on the Lisa…
For a while I’ve been struggling with occasional mystery bugs when making changes to the Floppy Emu AVR microcontroller firmware. I’ll make some seemingly innocuous code changes, and completely unrelated things will break. Frequently I’ll change something in a menu…
