Research Unix

<p>Research Unix refers to the early versions of the <a href="/facts/Unix/0pNL2seI">Unix</a> operating system for <a href="/facts/PDP-7/DzyogXEE">DEC PDP-7</a>, <a href="/facts/PDP-11/9HkGUzFn">PDP-11</a>, <a href="/facts/VAX/N3r13IHH">VAX</a> and <a href="/facts/Interdata_7%2f32_and_8%2f32/RSEFj02y">Interdata 7/32 and 8/32</a> computers, developed in the <a href="/facts/Bell_Labs/fKP5Gk0H">Bell Labs</a> Computing Sciences Research Center (CSRC). The term <i>Research Unix</i> first appeared in the <a href="/facts/Bell_System_Technical_Journal/JjXNS5y1">Bell System Technical Journal</a> (Vol. 57, No. 6, Part 2 July/August 1978) to distinguish it from other versions internal to Bell Labs (such as <a href="/facts/PWB%2fUNIX/jXR0LT4j">PWB/UNIX</a> and <a href="/facts/Multi-Environment_Real-Time/Gc0eJXYc">MERT</a>) whose code-base had diverged from the primary CSRC version. However, that term was little-used until Version 8 Unix (1985), but has been <a href="/facts/Retroactive_continuity/PAGRMnpb">retroactively</a> applied to earlier versions as well. Prior to V8, the operating system was most commonly called simply UNIX (in caps) or the UNIX Time-Sharing System.
