Andrew,

It would be my guess you have steppers. The colors are right for
some mfr's motors. 4 leads is a bipolar 2-phase stepper. 1988 retro's
prob'ly used steppers (servo's WERE VERY expensive, then, especially
compared to the $$ diff. between step vs, servo now) Of course, there
would be no encoders.

BUT, I am unfamiliar with the MFR in question, so these are just
guesses.

The motors have just about no information on them, but looking
inside, I see 4 wires: black, red, white,and green, which seem like
just enough to run <snip>
