Chris, the OEM manual for the SFD-321B is online at:
I note that they do use pin 2 as a density select pin and the OPA and
OPB PCB jumpers to determine the operating mode. You might want to
play with this a bit to see if you can coax it into operating in 2D
Whatever, please report back because I note that these drives are (1)
cheap and (2) have a provision to supply a READY signal instead of
DISK CHANGE. That could come in useful.
