Serious question (not meant to merely contradict Fred), what would it
take to do that for an RX01 or RX02? The drive mechanism itself in
a DEC 8" drive has no electronics - it's a motor, a head loading relay
(the drive motors spin whenever the unit is powered on, unlike modern
equipment), a couple of sensors and a head cable. All of the "work" is
done on the board above the drives.

Even getting past electrical issues, one trick would be how to low-level
format the disks.

Among other reasons for doing it is that I have an RX01 that came from
a client with a siezed rotation motor on one drive and a siezed head
positioner motor (with attendant incinerated head motor driver
transistors) on the other drive. Yes, I can repair the transistors and
move one good motor to the other mechanism, but it means that I have 1/2
of a full RX01.
