Yeah, it's a GE set, tube type. The set was modified for use in the game by adapting it to accept baseband composite video. Functionality wise, you can simply use any appropriately sized composite video monitor. If you want to maintain originality though, you'll probably want to find the same model TV. It was actually a pretty common model, although I don't recall the exact one off the top of my head. I also seem to remember that there were two different ones used in these...
