Any chance this terminal was refitted from a Death Star one? Just looks familiar...possibly from the detention area? Keep in mind this same room also had the exact same trunk that old Ben had in his place.

It was almost the exact same art department from Star Wars under Production Designer John Barry that worked on Superman I and II (not the Lester footage...) So I am reasonably sure that if his control panel wasn't one used in Star Wars, it was designed and built by the same people... just a few months later.
