[Orb] Pinballs

I own an old Fireball machine that I bought when I was 12 years old and a Teenage Mutant Ninja Turtles machine. I used to have a unique machine that I think was called two towers or something like that and you could "fire" the pinball from a cannon onto the back-board and play a mini game on the back-board. It was totally trashed however in the Northridge, CA earthquake. There seems to be an Orb - pinball connection going on! John Wintemute
