Well, that's really strange. And annoying to any operators wanting to put the game out on location.
As far as I know, all (or most, at least..) vids, redemption, use 110v models, so operators have multiple spare units sitting around. (Hell, I'm NOT an operator anymore, and I still have about 5 of them waiting for games..!)
But now, I can't use any of my spares. Have to go out and get a new one.
It's NOT MDB, so there's that, at least.
And I'm going to assume that the coin door wasn't changed, so which means a any of the 23xx-28xx series will work, as long as you have a compact bezel for an upstacker (xx[1, 4, 5, maybe D]x). The +12v Battery model (xxx5) should also work then, AFAIK.
