I reconditioned an "Orbit 1" a few years ago - really easy to fix and clean up. Not a bad game to play as well. I think it uses Gottlieb parts, but I can't remember the flipper assemblies.
I love this machine. It's in gorgeous original condition. Mitch had it for a while and cleaned up the cab, touched up the blue a little, but it's an original,
almost unmarked survivor.
I feel like a 70's cool kid when i play it, and i play it a lot. It's tuned really well, and once you learn where the danger is and what nudges get you out of it
it's great fun to challenge.
Simple rules for my simple brain and very few little cheats that no one knows, so a great leveler in comp.
If it was my only machine, i'd still be a very happy man.
There is a gottlieb with the same playfield. Can't remeber the name, but it's the same machine with a different theme.
