Hope your all sitting down for this. Yes it is a SS pinball machine this one belongs to my sons Karate instructor has owned it for years. Needed new rubbers and a clean so i pack my gear and head over to his place and learned a valuable lesson. Don't take peoples word for things i ripped straight into the tidy up removing all the plastics posts and globes etc polished, and waxed added new globes rubbers and a ball. turned it on to test the lights and the game didnt work. The battery had leaked and killed the cpu. Luckily Mark had a ultimate cpu in stock which got the game running again reflowed a few dry solder joints and replaced dead transistors on the driver board and it was a goer again. So all that work wasn't for nothing. Something i will never forget is to make sure everything works dont just take people word for it..
