In the DVD exclusive email "Accent," the Zappy XT6 appeared in Strong Sad's projector film which revealed what Strong Bad's changed voice would sound like in five years. This futuristic computer is a hovering, light blue, translucent screen with circuitry imprints on it and a logo on the bottom left. Below it is a holographic keyboard which makes cosmic sounds when Strong Bad types. The "XT6" in its name is a reference to 20X6.
