Codex Gamicus

Alto Trek is a computer game, developed by Gene Ball and Rick Rashid for the Xerox Alto while they were graduate students at the University of Rochester during the late 1970s. It's one of the first networked multiplayer games.[1]

Alto Trek is a multiplayer game where each player uses their own Alto workstation to control a starship. The objective of the game is to destroy the enemy without being destroyed. A player can choose between of being a Klingon, Romulan, or Terran. The game can be played by one player, but there will be no enemy to destroy.

The manual for version 2.1 is dated August 1979 and authored by Allen Wells, Bob Baldwin, and Steve Quarterman. It confirms that the game was authored primarily by Gene Ball.

Around 1997, while a vice president at Microsoft, Rashid began to reimplement the game as a way to teach himself to use the DirectX programming API. This resulted in the development of Microsoft Allegiance.[2]
