1983 To 1990
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 ease 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 associated proprietary 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.
In May 1983, the PDP-10-centered cultures that had nourished the File were dealt a death-blow by the cancellation of the Jupiter project at DEC. The File's compilers, already dispersed, moved on to other things. Steele-1983 was partly a monument to what its authors thought was a dying tradition; no one involved realized at the time just how wide its influence was to be.
As mentioned in some editions:
By the mid-1980s the File's content was dated, but the legend that had grown up around it never quite died out. The book, and softcopies obtained off the ARPANET, circulated even in cultures far removed from MIT's; the content exerted a strong and continuing influence on hackish slang and humor. Even as the advent of the microcomputer and other trends fueled a tremendous expansion of hackerdom, the File (and related materials like the AI Koans in Appendix A) came to be seen as a sort of sacred epic, a hacker-culture Matter of Britain chronicling the heroic exploits of the Knights of the Lab. The pace of change in hackerdom at large accelerated tremendously, but the Jargon File passed from living document to icon and remained essentially untouched for seven years.
