The 'standard' PC controller all the way back to 1982 is the NEC uPD765,
uPD765A, or uPD765A-2. Most PCs use embedded versions of these (original)
chips so you rarely see these letters on a motherboard.

OmniDisk (http://www.8bs.com/submit/omnidisk/OmniDisk.htm) will tell you
what the chip identifies itself as if you use the 'VER' command.

Subject: [BBC-Micro] fdc prog on a PC - which disk controller ICs work?


Hi all,

I tried my various spare PC motherboards a while back and despite them
all being from different eras, none of them seemed to want to read or
write BBC disks using the FDC program.

However I just unearthed a tiny ISA card with a UM8397 floppy disk
controller IC on it... any ideas if this'll work? Reason I ask is that
I'm going to have to build a whole new machine out of spares just to try
it, so I'd rather know it was going to work first :-)

cheers

Jules
