Hi Jules
Here is what I've found. It is a disk drive emulator.
Unless a PC is DMA driven, bit banging a floppy is not practical.
There are just too many other things that the PC is doing on
the side. Having a separate dedicated uP is the best way.
That device can then either communicate with the host through serial
or parallel.
