Yeah, this thing sat in dude's backyard under a covered patio. They would play it at night. Apparently, the patio became uncovered at some point

I'm waiting for the wife to get home from work (at a hospital) with some respiratory masks, lol. I'm gonna tear it down sometime this week. I hope the cabinet plans I found are detailed enough for my dad to build a perfect replica. jakobud.com is all I could really find.
Other than that, I found out the monitor is a WG 4600. Just what I wanted to begin with for my Galaga project. But a lot of wires are cut on it and the neck board is snapped in half on one corner. So I need monitor wiring stuff, a new neck board and the major wire harness that connects to the control panel. Then I can try to hook it up and see how it works.
