This game is a version of Advanced Rogue 7.7.
Michael Morgan, Ken Dalka, and their colleagues at AT&T kept working on Advanced Rogue after releasing version 5.8. Their game eventually had nine character classes, some with special conduct requirements. They also rewrote the time system.
In July 1986, they made a release numbered 7.7, the last surviving version of Advanced Rogue, though there are some references to a version 7.8.
The Roguelike Restoration Project found the source code "floating on the internet" and produced a restored version in 2006.
The Roguelike Gallery began maintaining Advanced Rogue 7 in 2015. Some bugs related to command repetition and saving games have been fixed.
