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.
