I have one. Unknown as to if it is working. Took it on trade. If you're interested, I can check it out. Looks to be original and complete with a good cab and glass, etc. Still has some tickets in it too. Fella i got it from said it was working. Near - Columbus Ohio.
Well, most of my question have been addressed -
I'm still curious:
1. Where to find the serial number,
2. Where the coin counter and ticket counter's mounted.
3. *Legible* copy of the effin' schematics.
From what I've been able to knock out -
1. The lock-down back was changed at some point to shoulder-bolts.
2. Wiring routing to the front door was changed at some point.
3. The backglass was changed (the red ink was modified)
4. Ticket holder was modified (early games didn't have hinge)
My game is early enough in production where it'd apparent it was built from parts laying around - chase light mounting is different on either side, the speaker grille was taken from another game and bent into shape..
Yeah, the game is almost worthless, sadly, but I always find production changes interesting.
