For a fan of the work of Douglas Adams this is like reading of the discovery of the Dead Sea Scrolls!
Journalist and computer programmer Andy Baio (no relation to Scott) received a copy of the internal network drive from the now-defunct computer game company Infocom, which in the early 1980s produced a text adventure version of the Hitchhiker's Guide to the Galaxy. Among the treasure trove were "two playable prototypes" of the sequel to that game: Milliways: The Restaurant at the End of the Universe.
Baio, who is my newest hero, has made one of the playable prototypes available online in a Java version. Here it is! You know where I'll be for the next day or two.
