Check the DS jumpers and the cable. Sounds like the controller thinks both are
A:, or the cable is reversed. The end with the "twists" (pins 10-16 I think)
should be on the A: drive, not on the controller. I've found a few "bad"
machines
that supposed experts have worked on done in reverse. Also a foam swab and
denatured alcohol on the heads cleans them up rather well.

I believe we have one 5160 with full height drives,
and one with half
height. I don't think either boots properly. Now at least we can get
them cosmetically cleaned up. As I recall they both seem to poll both
drives at once, or something weird like that. Shortly after I looked at
them, we lost power due to renovations, and that was 18 months ago. I'll
have to start all over again.

Actually, it was the 5160 I was curious about. Were they still using the
full height drives on them?
Yes. I have a 5160 in front of me here with official IBM-badged drives
that I believe to be original. And a couple more similar machines upstairs.
All are full-height Tandon mechanisms.
