it's a Namco board that shares the same pinout as Galaga and Bosconian, i believe, but i'd have to double-check to make sure.
i don't think there was ever a dedicated cabinet and it was never officially released in North America; it's a Japan and Europe only game.
over here the game is pretty darn rare. i do have a boardset with a JAMMA adapter (homemade and all the wires are red!) but i've never seen or heard of another one. it's not for sale.
the game is pretty cool. i was thinking of turning a spare converted Ms. Pac into a "dedicated" cab at some point but i need to find some good, HQ artwork for the marquee and sideart.
