Hihi. Well i think you rever to my post.
I repair a lot of pinball machines. Not the EM's because i realy dont understand them. But from all the machines i maintain the only ones that always boots and play fine are the System 3 flippers.The 10 em's always have problems because thay waren't played enough. But looking to the future EM pinballs will be the only ones alive. All parts from Solid State pinballs should be out of stock in a couple of years. But an EM pinball could be repaired with some paperclips
