Ah.
There was a time a while back when guy brought me a homebrew Xerox 820-1
system that had two different brands of 5.25" floppies in it, and I had what
it took going on in my head at the time to look at all of the lines and
whatnot and make it work.
Somewhere around the time peecee hardware started to take over I started
seeing less and less of those sorts of challenges, so those particular brain
cells have been sound asleep for a while now. :-)

Sort of, to use a 1.44 as a normal drive you only need to exchange pins
10 and 12 (which are the drive select lines), and not move the motor on
line. The normal PC cable twist exchanges both. There are a couple of problems however, most
1.44M drives are jumpered
to operate as drive 1 only, and cannot easily be changed, this can be
fixed however by swapping lines in the cable e.g. swapping 10 and 12
will make the drive respond as drive 0.
Hence the twist in the cable...
