ThisKensington Laboratories 4000A 3-Axis X-Y-Z
Servo Positioning Controller
Looks to be in good working condition
It powers up, and the fan comes on, and the lights on the Axis boards light up
However, this is the extent of my testing of it
showing some signs of wear and missing the top cover as seen in pictures
