The pinball bug

I was always interested in figuring out how things worked. Even as a kid I would disassemble toys.  As got older I became handy at fixing things and I had an interested on how electrical mechanical things worked. My hobby started over ten years ago by restoring video arcade machines. One day I found an ex arcade operator that had hordes of video arcades and pinball machines. He didn't want to sell to just any one. They had to know how to fix these neglected machines without calling him all day asking what's wrong with my game? He gave me 8 hrs of detailed training on the most common problems and repairs on solid state pinball machines. I bought two dead machines a 1979 Gottlieb Incredible Hulk and a 1978 Gottlieb SS Joker Poker. Then I was instantly bit by the pinball bug.....
