Gottlieb System 80B Gold Wings MPU and Driver Board Test

Chris Hibler walks through repairing and testing a Gottlieb System 80B Gold Wings MPU and driver board for a client, citing reset issues traced to a hacked daughter card. He replaces the daughter card and a 5V filter cap, restores NiCad batteries, plans to replace a slam switch solder glob with wire, and tests lamps, solenoids, switches, and memory before installing a free play ROM. Testing was done with a Quick Scan 80 that exercises the sound circuit Z13.
