Oh man, I really want to say that it's a Cinematronics CP of some sort, but I'm not sure. I just know that I've seen that CP on a Cinematronics game before, maybe Scion? It could have been a conversion though so don't take my word for it.
I've moved two different cabs with that same generic overlay. Also saw the same pattern with green and black as well. Reminds me alot of Gaplus in a way.
Okay, just was curious if it was something worth a poop or not. I've seen them a few places before but wasn't anything memorable obviously, so I'm deferring to you guys. Think it's just a generic overlay. How sad.
Bally / Midway used an overlay very similar to that one on some of their games in 1983. I think Gaplus looks a bit like it, and my Bull Fight overlay looked like that, too. There might've been a few of the other "6-pack" games which used something like that as well.
