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,…
While I’m optimistic that the floppy write emulation technique described yesterday will work (at least for high speed cards), it would be great if I could buy an extra safety margin of time, or find a way of throttling the…
My apologies for another post full of abstract floppy emulation thoughts, with nothing concrete to discuss and no photos to show. As readers have no doubt noticed, I’m having a difficult time wrapping my head around the best way to approach this problem.…
Which would you guess supports faster write speeds: a modern high-speed class 10 SDHC Flash memory card, or a vintage 1984 floppy disk employing a mechanical stepper motor to move its drive head, spinning magnetic media at a lazy 400…
