Several early units were shipped with @!?@ on the marquee instead of Qbert, and is referred to as the “swearing” marquee. Part of this games unique charm is the pure gibberish that comes out of the machines speech synthesizer. There was an erroneous rumor going around that the designer of the Furby is the original programmer of Qbert. This is untrue. The original Qbert arcade game was designed and programmed by Warren Davis with graphics by Jeff Lee and sounds by David Thiel. The designer of the Furby may have been one of the programmers of a Qbert conversion to a home system such as the Atari 2600, hence the confusion.
