Hi Mike,

I just tried this experiment. I plugged in a 110V AC to 12V DC
transformer (from Radio Shack) that I had laying around into the
3-pronged 110V female plug at the top of the MotoTrak. I then pugged the
cord from the transformer into a JMI 12V DC motor, the kind they use for
their MotoFocus and DEC slow motion kits. The DC motor ran, and the RA
slow motion buttons on the MotoTrak slowed it down and sped it up when
pressed.
