I’m finally getting to my 300 I picked up about a year ago. The previous owner did more damage than good trying to get additional players working. That took all but a minute to figure out that the stepper unit was seized up. I have been using this thread to get this game up and running. After about five games the whole machine went dead. That problem is fixed now.

A copy of a Top Score schematic is located here.

I now have the machine working about 90%. The last problem I have is the advance bonus is not rotating when the ball rolls over the switches. Although the schematic seems easier to read than a Williams, I’m just not seeing what switch makes these rotate. Thanks in advance.

Just ignore these pictures, was another question, but I figured it out.
