I had the game all working yesturday, now today I turn it on and I get a blue screen with white lines on it saying "Ram Access memory error" or something like that off the top of my head... how can I fix this?
Hope the RAM chip is socketed on the board, and replace that chip. If it's soldered on, you might want to look for ChannelManiac on here and ask if he can help.
power supply on one of mine walked to 4.77 (after I'd replaced and adjusted it to 5.2 only a few months prior!). the game would still load fine, and usually even play fine until there was probably too steep of a drop in power during attract and then it would scramble up.
just thought I'd throw that out. I'd say try reseating all the interlock boards first, make sure the filter board is attached tight, etc.
