I'll have to check out the game show docs. If you get a chance, seek out Big Bucks: The Press Your Luck Scandal special. It details how Michael Larson, an out-of-work ice cream truck driver used a then new devise called a VCR to tape the Press Your Luck show and memorize the light patterns on the Whammy board. He then got himself on the show and kept spinning until he'd won a then-record $110,000.
