Hi -

Picked this up the other day, would come up with some mild garble on
the existing characters, but crash when coined up. Sound was working.
General decline from there, to this image that I have now.

The power supply is giving a good +/-5V and 12V (measured on game
board). Swapped CPUs - same result.

Any ideas?

Thanks,
Maximus...

Get one of Scott's Multi game kits , it helps so much when fixing these
boards. Will tell you which ram to pull + plus 7 games to play!

Baraka, Braze, Mecw:

Thanks for the help - I agree - looks to be a RAM problem. Going to
try and track some down tomorrow or order on-line. I'm pretty good at
soldering, so I'll work on de-populating the RAMs in the meanwhile.

Thanks again,
Scott...
