Source Code for Zork, Hitchhiker’s Guide, and Other Infocom Games on GitHub

This repository is a directory of source code for the Infocom game “Zork I”, including a variety of files both used and discarded in the production of the game. ZIP files in some of the Infocom Source Code repositories but they were there as of final spin-down of the Infocom Drive and the means to create them is currently lost. Throughout its history, Infocom used a TOPS20 mainframe with a compiler (ZILCH) to create and edit language files – this repository is a mirror of the source code directory archive of Infocom but could represent years of difference from what was originally released.
