I have a machine from the 50's It is electromechanical slot. It has a controller that was behind the bar that would subtract points from the machine when you cashed out and you would pay the bartender he would add so many points on the machine. all I'm missing it that controller. does anyone have one? or the slot? I could use some info on the controller part. Right now I'm making a controller and getting some of the machine to work, but not everything. Help, Dave
