I am brand new to this message forum. I found it accidentally last week. I wish I found it years ago because it seems that all the questions that I have been having in the last thirty years, I am seeing on this forum. I have a personal collection of Bally EM machines and it seems that it is becoming harder and harder to find anyone who knows about them. With my limited knowledge, I have been doing the best that I can with the manuals and schematics that I have obtained thoughout the years. Trial and error takes hours, if not days and it is great to find this forum so that hopefully, I can find folks who can understand what I am going through in trying to maintain these collectables. My nomenclature might not always be correct, but I promise not to post without doing my homework first.
