Stern WhiteStar Kooky Carnival MPU test and Driver Board Parts Populated

Chris Hibler walks through repairing and testing a Stern WhiteStar MPU and driver board pulled from a Simpsons Cookie Carnival-type redemption game, replacing corroded parts, adding missing components, updating the OS to OS8, and verifying lamp matrix and switch function with Sopranos ROMs. He notes redemption-game boards ship under-populated and that Sopranos ROMs fail to report switch column six, a fix he attributes to the OS update. He also mentions selling a pristine Sopranos machine for $4,200.
