That isn't a real Atari cabaret in the link. I had a Centipede cabaret in my game room for a long time and that isn't one.
The coin door is in the wrong place, there is no sign on the inside that huge Atari transformer and fuse assembly was ever there. No holes on the right side where the old stuff would have been mounted. No service panel on top of the coin box, and no holes where it used to have been.
DPTwiz on klov sells brand new CNC cut centipede cabaret cabs for $400 so the plans must be out there.
Good observations, I thought something seemed off about it. The people who made it were obviously inspired by that particular cab then.
Does it have to be an "exact" replica? I experienced this same issue some time back and just decided that a 1/4" difference here or there really isn't that big a deal. Just wing it and make it look the best you can...
Nah, I'm not going for an exact replica. I'm not gonna make it quite so deep for one thing, plus I plan to use a Midway coin door since I really like them and I have one. Probably not gonna theme it after an Atari game either.
But having said that, I really suck at winging stuff like this. I'd love to have a plan to look at for stuff like how high should the control panel be and how tall is the monitor area.
