Open to offers on any of these. I finally decided to start sorting through the hundreds of boards I have. I'm not set up to test Pinball stuff, so everything is as is, untested. All the arcade stuff I have messed with so far have been split three ways between working, easily fixable or for parts boards. I would expect the pinball stuff to have the same split.

I will be adding more stuff as I sort through the boards and will add prices once I have found most of the Pinball stuff. In the meantime make offers. No issue with bulk selling to someone who can test, repair, and flip.
