This is one relative huge industrial robot with controller.  There are supposed to be 6 axis of servo motion--there are 5 big servo motors that can be seen--the sixth being hidden in the base.  Rated load is 150 pounds although it sure looks like it could handle a lot more at reduced speed.  It can reach out 100 inches and reach up to 139".  Rated speed is 40 inches per second.  While the company that made this is no longer around, there are a lot of these and information and parts seem to be relatively readily available.

Someone rather unceremoniously chopped off the wires between the robot and the controller.  While boringly  laborious it should not be that hard to reconnect them.  The controller weighs about 1500 pounds in addition to the 5250 pounds of the robot arm

  

The teach pendant is included.

     

The hour  meter shows only 2116 hours--this look consistent with the appearance of everything.

This controller includes a McClean Midwest Electronic Enclosure Heat Exchanger.
