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.

yes, please :-)
I remember asking about this a while back, specifically wondering if a
PC parallel port was fast enough to drive it (not without buffering at
some sort of level, it seemed)
I wouldn't mind seeing what someone else has come up with.
cheers

truly demented idea:
build a hardware device that can read the image file, connects
via 34 or 50 pin cable to an FDC, and that produces pulses
that look like disk data to the FDC.
Hi
It has already been done. I can look up the web page if you like.
