became a major draw. He and fellow employee Mary Cole ported STTR1 to DEC's BASIC-PLUS in the summer of 1973, with some additions, and he published this version in the newsletter. Ahl attributed the game to "Mike Mayfield of Centerline Engineering and/or Custom Data". In late 1973, Ahl collected many of the game submissions in the book 101 BASIC Computer Games, containing descriptions and the source code for many early mainframe games. 101 BASIC Computer Games was a landmark title in computer games programming, and was a best-selling title with more than 10,000 copies sold — more copies than there were computers in existence at the time. As such, the BASIC ports of mainframe computer games included in the book were often more long-lived than their original versions or other mainframe computer games. He included Star Trek in the book as SPACWR, i.e. Space War. Super Star Trek In early 1974, Bob Leedom saw Ahl's version of the game in 101 BASIC Computer Games while working with a Data General Nova 800 minicomputer at Westinghouse Electric Corporation and, having never seen a Star Trek game before, started porting it to the system. After he got the game running, he began to expand it with suggestions from his friends. He changed the user interface, replacing the original game's numeric codes with three-letter commands and adding status reports from show characters and names for the galaxy quadrants, and overhauled the gameplay, adding moving Klingon ships, navigation and fire control options, and an expanded library computer. Once it was completed, he wrote a letter to the People's Computer Company newsletter describing the game. Ahl, who by then had left DEC to start Creative Computing magazine, saw Leedom's description in the newsletter and contacted him to publish the game in his magazine. Ahl ported it to Microsoft BASIC and published the source code of the game as Super Star Trek to distinguish it from the original Star Trek game, calling it "by far the best" version. He later included it under that name in the 1976 anthology The Best of Creative Computing as well as the 1978 edition of 101 BASIC Computer Games, retitled BASIC Computer Games. He added a note that he had permission from the rights holders to use the show's name in the title alongside a longer note written by Leedom explaining why the galaxy had 64 quadrants even though the
