Game-Specific Issues
The Demo Man Cryo-Claw can sometimes be problematic.
At game boot, proper behavior is for the elevator to run through a cycle, then the cryo-claw will move all the way to the right (into the position to pick a ball from the elevator) and then move all the way to the left.
The cryo-claw motor knows when it is at the "end of throw" via two cams and two optos, which are shown on the board at left (Williams part number A-16986). Fractured solder joints on the optos are sometimes an issue, and the 470 ohm 1/2 watt resistors take a lot of heat. Fractured solder joints on the .100 right angle header is also a problem sometimes.
