There must have been a cable harness that plugged-in to this 48-pin horror, which had separate leads for the power input and special connectors for the motors.

I dug into docs for some obscure HP-IL peripherals from back in the day, and checked them to see if possibly applicable, but those devices are for controlling step-motors and look nothing alike, so not related. Sorry, not much help.
