From what I understand, those 2 working ones are for him and his brother. He was going to sell the 4th as a project game and then decided to keep it for spare parts for his machines. Since the 4th game wasnt completed, i agreed to take a look at another game for him that he had in his warehouse that he wanted working. He paid for the parts to get his 2 machines working, basically 2 cap kits and 2 high score save kits , and he provided marquee lamps and the black light for the one machine that needed it . I only provided labor for his and the parts for my machine. I should have expanded on that a bit. I think it would be fair to say that in the end we were both happy with the outcome.
