You can now download the source code of every Infocom text adventure game, thanks to archivist Jason Scott who uploaded the code to GitHub. “There are numerous repositories under the name historicalsource, each for a different game,” reports Ars Technica. “Titles include, but are not limited to, The Hitchhiker’s Guide to the Galaxy, Planetfall, Shogun, and several Zork games — plus some more unusual inclusions like an incomplete version of Hitchhiker’s sequel The Restaurant at the End of the Universe, Infocom samplers, and an unreleased adaptation of James Cameron’s The Abyss.” From the report: The code was uploaded by Jason Scott, an archivist who is the proprietor of textfiles.com. His website describes itself as “a glimpse into the history of writers and artists bound by the 128 characters that the American Standard Code for Information Interchange (ASCII) allowed them” — in particular those of the 1980s. He announced the GitHub uploads on Twitter earlier this week. The games were written in the LISP-esque “Zork Implementation Language,” or ZIL, which you could be forgiven for not being intimately familiar with already. Fortunately, Scott also tweeted a link to a helpful manual for the language on archive.org. Gamasutra, which first reported the news, notes that Activision still owns the rights to Infocom games and could request a takedown if it wanted.
