All that Infocom interpreter code

Jason Scott posted the source code for all the Infocom games in 2019. This was pretty awesome. Everybody who is interested in that stuff cheered, and now it’s part of the common knowledge of Infocom. If you’re researching the history of those games, or want to study their design, you can dig in.


So the game source was big news. Infocom’s interpreter source, however, remained obscure. This was the game-playing software for each platform: the Apple 2 interpreter, the Commodore 64 interpreter, and so on. A particular Infocom game release (“Zork 3 for the C64”, say) was a floppy containing the C64 interpreter and the Zork-3 game file. Boot the floppy, the interpreter starts up; it loads the game data and the game begins.

The code for the interpreter, however, was never released as open source – until now. Andrew Plotkin posted all of the code on Github, followed later by an additional code dump by David Fillmore.
