"crash" and "down" go back further than that. I'm looking at my copy of HoToGAMIT ("How to Get Around MIT") from 1972. In the Appendix there is a Lexicon of MIT Words, Phrases, Acronyms. The entry for "crash": "(1) To sleep in a place where one has not paid rent, such as a friend's apartment. (2) To join a party without being invited. (3) To cease functioning, as in a computer system." And the entry for "down": "(1) Feeling depressed. Said of a person. (2) Non-working, gronked. Said of a machine." The Lexicon occupies pages 222-232, so it isn't very long, and most of the entries are MIT-specific (such as acronyms for organizations). But there are some entries (like the one for "hack") which occur in the Hacker's Dictionary. HoToGAMIT was published by the Tech Community Association, and was distributed to incoming freshmen.
