A late version of jargon-1, expanded with commentary for the mass
market, was edited by Guy Steele into a book published in 1983 as `The
Hacker's Dictionary' (Harper & Row CN 1082, ISBN 0-06-091082-8). The
other jargon-1 editors (Raphael Finkel, Don Woods, and Mark Crispin)
contributed to this revision, as did Richard M. Stallman and Geoff
Goodfellow. This book (now out of print) is hereafter referred to as
`Steele-1983' and those six as the Steele-1983 coauthors.

Shortly after the publication of Steele-1983, the File effectively
stopped growing and changing. Originally, this was due to a desire to
freeze the file temporarily to facilitate the production of Steele-1983,
but external conditions caused the `temporary' freeze to become
permanent.

The AI Lab culture had been hit hard in the late 1970s by funding cuts
and the resulting administrative decision to use vendor-supported
hardware and software instead of homebrew whenever possible. At MIT,
most AI work had turned to dedicated LISP Machines. At the same time,
the commercialization of AI technology lured some of the AI Lab's best
and brightest away to startups along the Route 128 strip in
Massachusetts and out West in Silicon Valley. The startups built LISP
machines for MIT; the central MIT-AI computer became a {TWENEX} system
rather than a host for the AI hackers' beloved {ITS}.

The Stanford AI Lab had effectively ceased to exist by 1980, although
the SAIL computer continued as a Computer Science Department resource
until 1991. Stanford became a major {TWENEX} site, at one point
operating more than a dozen TOPS-20 systems; but by the mid-1980s most
of the interesting software work was being done on the emerging BSD UNIX
standard.
