The connection to the motor is a lot like a PS2 type keyboard connection.
I'm wondering if there's some software that can emulate the controller, and if I can get a USB cable with PS2 jack on the other end and plug it into the controller? Maybe a bit of DIY, but not sure where to start? Any ideas?

Troy,
Congrats on reviving the old mount.
The PS2 connector is just a generic 6-pin mini DIN connector so it doesn't imply that any standard signalling scheme has been used. The chances that they've used something signal compatible with USB (a high speed serial protocol) are vanishingly small. If you're handy with an oscilloscope you might be able to figure out what is going on, but you'll probably need some fancy hardware to emulate the controller.
Cheers,
Rick.
