Mario Teaches Typing is a licensed edutainment game developed and published by Interplay Productions. It is one of the few licensed Mario computer titles. Mario Teaches Typing was originally released for MS-DOS in 1992, where the user could either use two 3'5" floppies or a single 5'75" one. It was later released on CD-ROM for Microsoft Windows and Macintosh in 1994. As the title suggests, Mario Teaches Typing was designed for improving a computer user's typing skills. All of the game's music was sampled from Super Mario World. Mario Teaches Typing eventually spawned a sequel in 1996, Mario Teaches Typing 2.
The MS-DOS version is the very first Mario video game where Mario speaks. In that version, he was voiced by Ronald B. Ruben. In the CD-ROM Windows and Mac versions, a floating Mario head acts as a narrator and guide to the game, this time voiced by Charles Martinet. This is his very first appearance in a video game as Mario, predating his major debut in Super Mario 64 by two years.
