I'm helping a guy out with his centipede, and he's not a technical person, and first off, he tried to replace his big blue.
The first time I saw the game, this is how big blue was wired.

After sorting that out, (and finding the correct screws for the replacement cap....)
The board came up with 10 beeps, so I replaced the ram at n5, and that brought the machine back to life.
But.. the colors were wrong...
Now the original reason I was called upon to help is that his monitor had died, and he took it to a local guy, that hooked it back up, it ran for a day, then smoked and died.... (k4900 I'm trying to find a chassis for)
I took a extra g07 I had on the shelf, but hadn't tested in years over to the location, and put it in and noticed to colors were bad, so I thought the monitor was bad and I forgot to label it.
So I grabbed my old faithful K4600 out of my Multiwilliams (It looks fine, colors are great), and took it over tonight, and same bad colors.
Here's the attract screen.

And here's the colors when I'm cycling the colors in test mode.

Any suggestions?
The game seems to play fine, the sprites are there, collision detect is working fine.
Also the wiring harness seems to be unmolested.
(Also, anyone have a link to the schematics???)
