Ok here i am again..
Baby pac man communication errors. when you push the coin door button you get trash on the screen. when you push the Vidiot test switch you get the communication test with all F1's down the left hand side. and nothing on the right hand side.
Here is what i have done.
Replace ALL .1" molex headers on Vidiot and MPU and Connectors on wires with crimp and solder type.
MPU - Replaced u8 Socket tried three different 5101 chips. replaced both u11 and u10 , rebuilt with a great plains corrosion kit (5volt detector), replaced all .1 headers
Vidiot: (i have tried two different vidiots with same results._ repalced u8, u1, u1, u3, u5, u4, u35, u6, u7 u13 and u14. Rebuilt the 12 and 5 volt regulators. reaplced Pots for video out and sound out. tried diffrent Romchips. diffrent u19-u26 ram.
And other stuff... What am i missing. were could this F1 error be.
