Coindoor and Cashbox
First, lets talk about the coin-door & cashbox. They're in good condition, this cabinet was home cared, and the coin-door really show a lack of use. Just a bit of grime and rust. The previous owner didn't have the keys for the door, so I'll have to replace the cam-lock, as well as get another one for the cashbox entry.
Inside the cashbox, lo-and-behold, a quarter! .25 cents off the price, woo-hoo! Savings!
In the coin door there is a service switch bench assembly that works very nicely.
Inside and to the right there is a installed Volume rod which works fine, and can really turn the volume up pretty loud!

The Innards
Ok, lets go around to the back and look at the electronics.
First, the plug. Looks like the grounding prong is missing...Is this normal? I've seen it done on other cabinets, and always wondered why.
Mounted on the inside of the back-door, there is a row of lamps that I'm assuming were used for lighting up the monitor bezel artwork at the top. Really cool idea, and I will definitely get these lamps replaced.
All the boards look pretty good, so I won't put too many dupe photos of them up again. But here are a couple.
Here's a shot of the battery holders. They're in awesome condition, but they're going to be removed and replaced with my battery upgrade. It's just better for the long-run. I will most likely put this up for sale if any collectors want it.
The monitor tube says it's a Toshiba...though I've yet to identify the chassis.
Eck, gooey substance on the overdrive pots...
Original linear power-supply, and a shot of the fuse diagram for reference.
So, that pretty much sums up the evaluation. Next thing to do is a order of attack, what I want to have happen during the restoration process, and how much it's going to cost me.
I won't be able to start working on this till later this month, but I would like to get it functioning without that crashing problem.
I've noticed that I can play the game for about 5-10 minutes from a cold start before the crash happens, then afterward only up to wave 5, (usually about 2-3 minutes). This leads me to believe that there is something failing after the initial warm-up.

While a favorite game, I know zero about the guts. So don't laugh when I ask: What's the red seven segment LED down lower left? Some sort of checksum indicator?

I believe its for codes to evaluating and recognizing error conditions with the board.
