This sounds like the (non-working) Calcomp I just gutted for parts. I have yet
to determine the characteristics of the two servo motors, though, other than
knowing a ballpark voltage. I kept the control panel intact; hopefully I can
someday figure out its interface (especially for the 2-line display screen),
because it looks like the ideal keyboard (+joystick) for a CNC controller.
