Non-Apple SD Floppy drive Emulator - DIY

It is a very smart device, designed by Jean-Fran├žois DEL NERO, adopted to 3,5' case by Jeff and Lotharek. It allows you to emulate any 34 pins floppy disk drive. The SDCard HxC Floppy Emulator can replace different kind of floppy disk drive and allows you use SDCard media instead of floppy disk. This emulator is actually used on Amiga, Atari, CPC, PC computers, different keyboards and samplers, CNC machine tool, and scientist instruments.┬á
