The source code for 45 Infocom text adventures is now available in its native ZIL (Zork Implementation Language) from GitHub.

According to the code repository’s readme file, “This collection is meant for education, discussion, and historical work, allowing researchers and students to study how code was made for these interactive fiction games and how the system dealt with input and processing. It is not considered to be under an open license.” But notes Gamasutra, “… Activision, which purchased Infocom in 1986, still owns the company IP, meaning it could eventually clamp down and halt Scott’s preservation efforts.”

To commemorate the release of this code, GitHub will host the live event “Game On I: The Great Quest for Imagination“, on the afternoon of Friday, April 26, 2019, 3–6:30 PM PDT (UTC-7) at its headquarters at 88 Colin P Kelly Jr St, San Francisco, California, USA. Steve Meretzky, the sole or lead designer on such Infocom games as The Hitchhiker’s Guide to the Galaxy, A Mind Forever Voyaging, Planetfall, and Leather Goddesses of Phobos, will be the guest of honor. The event will be moderated by Kevin Savetz of the Eaten by a Grue podcast. Topics will include Infocom, working with ZIL, putting the source code on GitHub, and the evolution of software and version control. Following the discussion will be a happy hour, during which game stations will be set up all where people can have fun with Infocom titles and multiplayer games. The event is open to the public; free registration is required. It will also be livestreamed online.
