I have a PE PLUS that was playing fine. I followed the Bill Validation directions in the posted thread. After Using the Set Chip I Enabled, Saved, and reinstalled the Program chip. When I turned the machine back on it cycled through the Testing Memory mode and then displayed “CALL ATTENDANT, CMOS DATA ERROR. I don’t See how to get Out of this lockup. I made sure that there were 0 credits on the machine. This thread didn’t mention Anything about Possibly needing “CLEAR CHIP” and then “SETUP CHIP? Any thoughts or Suggestions would be FANTASTIC, Thank Yoh.
