This item has been discussed recently, and I found myself figthing this
same floppy diskcontroller in my Lilith external floppydrive.
This is a 6502 subsystem with 4K rom/4k ram, a 9600 baud serial channel
( goes to the Lilith ) and said floppycontroller.
Symptoms :head goes to track zero, no directory is found.
I did not find a schematic on the net for this floppy controller.
When backengineering it I found that both Proms and the 74174 have their
power switched. Why would that be ? seems very hairy to me.
If anyone has such a controller and/or floppy drive available I'd be
interested. ( Switzerland )
