The original Jargon File as it was called (at least in 1982 by some on Usenet). It was a collection of hacker jargon from technical cultures including the MIT AI Lab, the Stanford AI lab (SAIL), and others of the old ARPANET AI/LISP/PDP-10 communities including Bolt, Beranek and Newman, Carnegie-Mellon University, and Worcester Polytechnic Institute. It was begun by Raphael Finkel at Stanford in 1975. From that time until 1991, when the plug was pulled on the SAIL computer where the File was located, it was named AIWORD.RF[UP,DOC]. The versions were all unnumbered and are collectively considered "Version 1".

In 1976, Mark Crispin FTPed a copy of the File to MIT where it was, shortly after, renamed to JARGON >. In 1990, Eric S. Raymond released Version 2.1.1 of the Jargon File after its seven-year hiatus.
