I have a Black Hole pinball machine. There is def some work that needs to be done on it. I'll tell you what I know and more than happy to answer any questions on it. The pinball machine does power on. Most of the switches and drop downs go down and come back up. Most of the lights work and the ones that don't need new light bulbs. I flipper do not work. I am not sure why. The other thing that I know doesn't work is the solenoid that fires the ball from the lower level up to the top. That will need to be addressed as well. Right now the back is off as that is the only way to get it out of the basement. One of the harnesses that connects the back to the main unit is cut and needs to be reconnected. I cut them because one of hte wires is soldered into the circuit board and it was easier to cut it.
