I think Demolition Derby really was a cocktail. Came with a 25" monitor IIRC.
Yeah, what I should have said was a "traditional" cocktail. It was a standup table. I still have the control panels from it, but not the table itself.
Awesome! I spend one whole vacation visiting my grandparents playing that, or begging my grandparents to take me to the arcade so I could play it.

Four player, standup horizontal, two on each side. Haven't seen one of these since forever.

Atari football, atari soccer (need trackballs for both). There's four player versions, too.
They're really horizontal games, but for atarifb at least, it's better played on a vertical cocktail when showing the football plays selection art (needed so you can tell what play you're running).
