Picked up the pinball machine today. The Thrift Store has no idea what is wrong with it and the system will not turn out. I took a look inside and found that there are a lot of un-familiar, older parts that I am not sure about. I am going to need to take some time to figure out what each component is and what its function is. Luckily, i found the system schematics inside so I have something to go off of. There is also a lot of rust and dirt buildup so that will probably affect to functionality of the system. Will spend the day just cleaning up areas.
