NIght Moves by International Concepts System 80B MPU Weird Lockup Issue - Solved - Failed U6

NIght Moves by International Concepts System 80B MPU Weird Lockup Issue - Solved - Failed U6 After I made this video I realized that I had not mentioned which chip actually failed. The culprit was U6, the 6532 RIOT that drives solenoids. This is the first time in many, many years of System 80 board repair that I have seen U6 fail.
