I think it's Fathom that Bob Thomson told me doesn't have a Game Over attract mode - the feature lamps just stop wherever they are when a game finishes. He reckoned there wasn't enough memory space to provide an attract mode, and he was the sort of guy who'd have known.
But then Centaur doesn't really have a proper one either; left to itself, the game simply speeds up the light show used during the 'Instruction Mode'*.
* Pressing either flipper button with the game idling starts up that taunting reverbed speech, beginning with "Challenge Me!", while the lamps are used to highlight the Orb, Sequence, Chamber, Guardian and Bonus features, in turn.
