File organization and details
zork
The files within this directory are the Zork specific files from the 100068.tap tape image file within the /tots/recovered/vol7 directory of the ToTS collection. Most files are written in the MDL programming language and were originally created on a PDP-10 timeshare computer running the ITS operating system.
The files were extracted from the tape image using the itstar program. The filenames have been adapted to Unix conventions, as per the itstar translation. The original filename syntax would be formatted like, LCF; ACT1 37, for example. All files have been placed into this artificial zork directory for organizational purposes.
The lcf and madman directories contain the source code for the game.
The act2.27 and dung.56 files outside of the two main directories, are the decrypted versions of act2z.27 and dungz.56. The decrypted versions were created recently and added to this directory by DDC digital archivist, Joe Carrano, for researcher ease of access.
Files with extensions .nbin and .save are binary compiled files.
There was a zork.log file within the madman directory that detailed who played Zork at the time of creation. DDC excluded this file from public release to protect the privacy of those named.
