If you want to *write* 8-inch disks, you need something to generate
the TG43 (Track Greater than 43) signal that controls the write
current. Not necessary if you only want to read.
The D-Bit FDADAP floppy disk adapter can be used if you don't want
to wire up a random cable. It also has a PIC that generates the TG43
signal.

if you don't need the TG43 signal, the rest of the pins are sequenced
relative to each other similarly enough that you can crimp a cable,
with just a few wires that need to be changed around.
