If you find one that can control a stepper motor, let me know.

When I got my 7.5" Byers drive, it just had some bare ended wires coming
out the AC motor. There was a cryptic wiring diagram on a little 4x5"
piece of paper, and that was it. There were only three wires involved,
the ground and the 2 AC wires. I used the cord from the old Meade RA
drive, and I just spliced the wires together and see what I got. The old
Meade cord had a typical 3-pronged AC plug, and that went into the
outlet on the MotoTrak. The first time, it rotated the scope to the
east, which is great if you live in the southern hemisphere. I reversed
the AC wires, and it worked correctly, ie, rotated the scope to the
west.
