Donkey

Donkey, often known by its file name DONKEY.BAS, is 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. The game was written by Microsoft co-founder Bill Gates and Neil Konzen.

DONKEY.BAS was written by Gates and Konzen to demonstrate the IBM PC and the BASIC programming language's capability to produce interactive programs with color graphics and sound. The game continues to generate interest in part because of the involvement of Gates at a time when Microsoft was relatively small and only six years old.
