AtomicChuck - I just picked up its twin game, Coffee-Mat's Cosmic Wars. Everything looks identical except the playfield layout.
I'm attempting to get mine going right now, and it's a huge amount of work. If you were a little closer, I'd definitely be interested in buying yours. I'd much rather see someone attempt to revive and restore it, but if you do end up parting it I'd be interested.
BTW, watch out for that bottom metal cabinet extension. On mine, it was not connected in any way - it just lifted right off the top portion of the game (although there was foam between which kind of held it together like double sided tape). Made it much easier to move though once it fell off.
