Lode Runner (by Douglas E. Smith) has been available on many different platforms over the years. The game was originally developed in Fortran on a VAX 1 owned by the University of Washington. While under development the game was disguised as a program called "graph" which when executed would request a function. Unless the user entered the correct password the program would crash. Eventually the password became common knowledge among the students and often nearly all of the users on the system would be running the program.
When it was completed the game was rechristened "Kong". Eventually Doug rewrote the game in 6502 Assembly on an Apple II+ he borrowed from a friend (this time renaming it "Miner"). In 1983 the game was picked up by Brøderbund and Doug dropped out of school to work on it full time. Although Brøderbund is now owned by Mattel Interactive, Mr. Smith still owns the rights to Lode Runner.
