Zork

/zork/, n.

The second of the great early experiments in computer fantasy gaming; see ADVENT. Originally written on MIT-DM during 1977-1979, later distributed with BSD Unix (as a patched, sourceless RT-11 FORTRAN binary; see retrocomputing) and commercialized as ‘The Zork Trilogy’ by Infocom. The FORTRAN source was later rewritten for portability and released to Usenet under the name "Dungeon". Both FORTRAN "Dungeon" and translated C versions are available at many FTP sites; the commercial Zork trilogy is available at http://www.ifarchive.org/. See also grue. You can play Zork via a Java Applet.
