In 1957 My father bought into a pinball route with one other person. This was in San Francisco, CA. I graduated from high school that summer and was taught how to convert Bingo pinball, mostly Balley and United machines to comply with the rules in San Francisco. I was then my father's mechanic. I also repaired games for other pinball owners. As you are probably aware bingos were "found to be gaming devices" and were no longer legal. I then found a job through the stationary engineers. I retired in 2006 and moved to Dunsmuir California. Several years ago I found out about the Picific Pinball Museum. Amoung his many flipper machines he had some bingo machines that need repair and I some of them for him. Then I got sick and had a major operstion. I would now like to repair EM machines in our area.
