Technically, the turntable on 80's Wheel would also fit the initial description too. Didn't $oTC's Winner's Big Money Game also have two sorta circular stands come from opposite sides of the stage to the center at the beginning of the round, as well?
Yep.
-I think the early seasons of GSN's
Newlywed Game feature a rotating set
-The contestant island on
Classic Concentration slid out the way for the car round, and back in for the rebus portion.
-And for the
Hollywood Squares half-hour of the MG/HSq hour, an upper tier slid onto the stage...although as Chris mentioned, it was probably stage hands giving the illusion of a magic desk*
If there's something I truly miss from the good ol' days, it's moving set pieces, whether it's a door or turntable.
*And I'd rather keep it that way ;-)
