infocom/source/Index

ZIL source code for the Infocom games.

The "modified for Mac" versions set a fixed-width flag on ASCII art so that it displays properly on Infocom's Mac interpreter, which supported proportional fonts. (Later releases also set this flag, but these versions were the first ones to have it.)

Zork 1, 2, and 3 are available under the MIT License. See [Microsoft's announcement](https://opensource.microsoft.com/blog/2025/11/20/preserving-code-that-shaped-generations-zork-i-ii-and-iii-go-open-source) (November 2025).

Infocom's other games are not yet open-source and therefore are not available here. Yet.
