This is a field kit board in a Ms-Pac cabinet and it comes up with different garbage on the screen when powered up. Screen never changes once powered up. Diagnostics is dead. Voltages seemed to check out OK.
How does everyone check their RAM chips? Not sure if it's the Z80 processor having issues, Rom's or Rams.
Any suggestions on where to start checking the components and how?
It had been working a while back and then just quit.
