Drat!

They sell 5 or 6 of them at the arcade auction here, but since they make so much cash in bars and so many people want them for their dens, they go pretty high...
Well, to answer my own question for the archives, I eventually found similar style games emulated in MAME, but they don't have the polish.
They are sorted in "genre 0.97u1" as "Multiplay *Mature*" There are one or two in the plain "Multiplay" category too.
There's also a pretty cool game called "multi-champ". It's built on 3 buttons, and has various "twitch" games. Kind of addictive.
