Hey guys, Picked up a pinbot today... was working when I went and picked it up and now I get GI lights and a "single" flash on the main board. Tells me it's the u25 ram chip. Is there a way to reset this or do I just need to order one? any ideas on part numbers? while I'm at it I thought I would upgrade sound and rom chips as well... not sure how to find what the latest update is... thanks for any input.
