Well, I worked on 3 of their redemption machines there at the drive-in theater. Keep in mind that I've never worked on a redemption game in my life. Got 2 of the 3 going and I brought the main board back home with me from the third machine as it had two bad driver transistors that were unobtainable out there in the sticks of Oak Harbor, Wash.
I got 3 of the 5 video monitors fixed with just the tools at hand. Two of the monitors were unfixable as the circuit boards had been stolen right off the monitor frames!
I got 2 of the 3 pinball machines running with some parts from Radio Shack, but the third machine had some broken parts that need to be ordered from a Williams pinball distributor.
