DONKEY.BAS

Donkey, often known by its file name DONKEY.BAS, was a computer game written in 1981 and included with early versions of the PC-DOS operating system distributed with the original IBM PC. It is a driving game in which the player must avoid hitting donkeys. While extremely simple compared to later PC games, and to games available for other systems at the time of its release, DONKEY.BAS is arguably a predecessor of all IBM PC games. The game is also notable because it was co-written by Microsoft co-founder Bill Gates.
