One thing I am wondering is if an 8-bit floppy controller card (the ones
from the PC-XT generation, which didn't have floppy IO on the
motherboard) could be modified (if needed) and contrived to work in a
more modern system that still has the ISA bus. If the particular I/O
locations are being used, simple cuts and adds could re-direct the I/O
ports. This would give the enterprising programmer a 765 controller
with relevant hardware to plug additional drives into. The original
PC-PC/XT controller is fully documented in the TechRef, and even has all
the cabling in place to support four floppies.
Gee I posted about doing just that. If the machine has ISA there is no
need to mod the card. Just disable (in bios) the mainboard level FDC and
plug in the ISA unit and go.
Also PCI cards work nice for that.
