I'm trying to preserve a relic of computing, 1975 style, and one bit of
this relic is an RX01 drive -- that is, a dual 8" floppy drive.  I have
two of these, and I face a decision:  Should I scrap the broken drive or
fix it?

To fix my broken RX01, I need to replace a Warner Electric stepping motor
(4 windings, common return, 24 volt) used to drive the head positioning
lead screw.  The one I have has one winding shorted out (this blew a
drive transistor, but those are pretty generic animals to replace if I can
get a good motor).

The broken drive also has a broken hub clamp assembly (specifically,
the retaining clips and other mounting hardware that hold the hub clamp
to the drive are missing).  For the curious, the hub clamp is the thing
that holds the center of the diskette to the drive spindle when you close
the door on the drive.

If anyone out there has already begun to cannibalize a DEC 8" floppy drive
for parts and is willing to part with the stepping motor and hub clamp
retaining hardware, please get in touch with me by E-mail.  Otherwise, my
second RX01 drive will itself become a target for cannibalization.
