Wild-hair floppy drive question

[Fred Cisin]

connecting a floppy as DS0:

if you're not willing to trace the jumpers on the drive (almost all have
at least solder pads!), then cut the traces of pins 10 and 12 and put a
jumper wire from pin 10 of the connector to where pin 12 used to connect.

... or, do it like RS did,...
short 10, 12, and 14 on the drive together.  Then remove pins from the
connector on the cable, so that each connector has only one of 10, 12, and 14
