I have an off topic technical question on a friends cocktail Donkey Kong. He was having trouble with it booting up. I'm not much of a vid guy but I was able to diagnose no 5 and 12 volts. Swapped in a new power supply and everything is up and running. The machine will not remember high scores or credits with an on/off power cycle. I figure this thing must have a ram chip somewhere that's gone bad or cap that's gone bad. I was hoping someone in here might direct me in the right direction and save me some time researching. I don't care to learn much about vids...it's a waste of my life...I'm a pin guy. Thanks in advance for any help!
