I'll spill the beans.
It's a friend of our's that got the thing... He's a Midway Jamma guy... that's it. Midway "box" cabs (KI, MK's, etc etc) only, and I don't think he's ever bought a non-Jamma game without the intent to flip it.
He wants me to work on it for him because I repaired my Space Invaders. I've been putting it off because I'm PRETTY sure he got it just to piss me off. lol
I'll be swinging by his house tonight, probably, to look at it... I'll try to get some pictures if anyone is interested. The cabinet is in great shape. I think he just needs the power supply rebuilt (I doubt there's a kit for this version), the boards looked at (screw me) and the monitor rebuilt (probably no kit for the monitor either).
I'll take a look at it and see WTH he's gotten me into.
