A couple of months ago I found about 25 arcade boards over a couple of barns on one of dads farms (no joke!). I've returned home with one box that was marked "good". I don't have much in the way of hope of the boards operating as they have been poorly stored. I have a couple of questions. 1. What prep work should i do to the boards prior to testing 2. What is a decent affordable super-gun that isn't going to damage my equipment and/or the boards 3. Any other considerations. Photos of one of the barns.
