What is this?

Thanks for posting that top picture. That lever is exactly what I pictured, but I had no idea what the front looked like.

In fact, I started doing a frantic Google image search after I posted my guess in the hopes I would find something that would look like the image in my head. I found nothing, but I guess that's because this thing is now decades old.

I really enjoyed this installment of the game. It was a challenge. Thank you, sir.
