One thing I am wondering is if an 8-bit floppy

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.
It will work, at least on machines I've tried. I've had exactly the
same problem as the restr of you -- only one pin for one drive select
on the board, so only one floppy where I need (at least) two. And the
BIOS behaved once it saw there were two floppies there.
