Gary,
Are you sure it was steppers? I never had any experience with those, my Bandits used resolver based servo motor control, with tach and resolver. The motor logic was part and parcel within the controller, so it is a case of keep the original intact and running, or scrap it.
It may make some sense to go to the effort to save the motors. To modernize them (if they are servos), a person could remove the resolver and install an encoder on the end of the motor. That is about the extent of what I would bother to save. All the antique power supplies and cards within the controller would be better off replaced with something new (and quiet, and cool running). There might be a few bucks to be made off the old cards if you pawn them off to one of the shops that still services Bandit, if they have need for the cards.
