looks like Elcon made some pretty generic but dedicated games in the late 70's; their most popular might have been Cosmic Attackers judging from the amount of literature on it vs. their other games.
it looks quite a bit like one of the ATW/Eastern Micro Electronics generic (and sometimes dedicated) cabs but those have small marquess above the monitor.
Thats how kki tripple punch locked.. but when you opened the top you had access to the PS and pcb. I think the monitor sort of folded/pulled out from the front to access the back of it.
It seems to me I've heard those referred to as "Artic" cabs, which I assumes is the maker. It's probably a generic cab for kits and whatnot, I think Funspot has Woodpecker in one of those.
I really like the look of these too. I one with a Frogger in it for a few minutes once! The particle board had been sitting outside for a long time in the seller's back yard and took on so much water it fell apart as I put it in my truck.
