Mysterious CNC Machine

This CNC Machine has been sitting in our barn for an unknown number of years. It appears that a student or mentor made it themselves, but no current members know where it came from. We understand how it works mechanically, but our question is how do we go about controlling it.

1. Assuming this board still works, how do we connect and control it?
2. Is there a board that could replace the current control board?

Thanks for any help. We want to get this working because we don't have any other CNC capabilities.
