What's amazing is this thread. I remember this pin from back in the day, never played it but had seen it a few times in an arcade I would go to. I've never seen one again, until this thread.
I thought I saw a picture of it recently, but it was what's suppose to be the largest pinball machine ever made, the one with the large white ball that looks like a cue ball and the big
black flippers.
I think I've seen the middle earth pin in some movies from the 80's, but I can't remember
which one it was. The backglass art is something I remembered, I think the atari logo is
somewhere on the backglass.
Nice find, good work in getting it up and running.
