Mark Allen (software developer)

Mark Allen is a software engineer, game programmer and game designer. As a student at the University of California, San Diego, Allen used UCSD Pascal to develop a 6502 interpreter for the Pascal language in 1978, along with Richard Gleaves. This work later became the basis for Apple Pascal. Later, Allen developed a number of well-received computer games for the Apple II, including "Stellar Invaders", Sabotage and "Pest Patrol". In particular, Sabotage became a classic of the Apple II games scene.

A clone of Sabotage was shipped as a standard piece of software on early iPods that had displays. It was called Parachute.
