I noticed that the letter arrangement of many of the game boards on the 1987 Bill Rafferty version were also used in the 1980-82 Bill Cullen version, but I wonder if one of the boards used later in the Rafferty run - the one that had the Y, Q, and Z clustered together - was also used in the Cullen version at some point?
Also, I did see a clip from a Bill Cullen era episode on YouTube and that was from a round that had the letter X on the board (key in \"Blockbusters X\" in the YouTube search engine and you can find it). What I ask is, was the letter X used at least one time on Bill Rafferty\'s run, and if so, when? I know it definitely wasn\'t in January 1987 as I recorded all of that month when GSN last aired the Rafferty version during the first quarter of 2009.
