The new Floppy Emu prototype is up and running at last! Today I was able to boot a Mac Plus from the new emulator board for the first time. It’s still rough around the edges, but it works. Copy a…

Floppy Emu has both a microcontroller and a CPLD working in tandem, and both must be programmed in order for the emulator to function. However, I don’t want to require two separate external programmers and the associated port connectors. My…

After months of procrastination, I finally assembled the Floppy Emu board and began work on the firmware modifications this week. So far, so good! Despite being out of practice with soldering, the assembly went smoothly, and the board checked out…

It took longer than I’d expected, but all the parts needed to build three Floppy Emus have finally arrived! That’s three custom-made circuit boards from Dorkbot PDX, plus the SD card sockets, CPLDs, AVRs, and a whole pile of buttons,…

Today I ordered the parts needed to build three Floppy Emu boards, the Macintosh floppy disk drive emulator. Everything should be here by next week, so I can start building! In these small quantities, the total cost for the parts…

Whew! It took me a long time to do the board layout for the floppy disk emulator, but here it is! The board is about 4 x 1.75 inches, or roughly the size of an elongated credit card. The resistors,…
