Pac-Man Board Game- totally had this! White glass marbles were "eaten" through a hole in the hollow plastic PAC man. Not sure we ever figured out the game play rules, we just messed around with the pieces.
A 45 rpm adapter (also 45 rpm record insert, or 45 rpm spindle adapter) is a small plastic or metal insert that goes in the middle of a 45-rpm record so it will play on a turntable. The adapter could be a small solid circle that fits onto the bottom of the spindle (meaning only one 45 could be played at a time) or a larger adapter that fits over the entire spindle, permitting a stack of 45s to be played.
