As far as maintaining the machines, what are the major issues? Regular cleaning and lubrication? I have a pinball machine that was made around '95 and I have no problem fixing that if anything goes wrong, breaks or something goes wrong with the wiring (myself being an electrician help). I dont know if anyone here is familar with the inner workings of a pinball machine, but they can be very complicated. Can anyone provide a picture of the inside of typical slot machine?
