[TUHS] Government-Issue UNIX?

[Clem Cole via TUHS]

Matt,

You asked: * "**if there was ever an attempt by the U.S. or another
government to license with AT&T to create a government-issued version of
UNIX."  *

   Taking your question in a different direction than some of the
other responses, where do you see FIPS-151 fit in relation?  For many
years, the FIPS (Federal Information Processing Standard) was a formal
requirement if a system was to be sold to the USG.  In fact, NIST(part of
the US Dept of Commerce) wrote a test suite to check to see if an OS
conformed to FIPS-151 [it's described here:
https://nvlpubs.nist.gov/nistpubs/Legacy/FIPS/fipspub151-2-1993.pdf — and
today the suite is referred to as VSX-PCS].  The Open Group now maintains
those test suites, which anyone can download if they like:
https://posix.opengroup.org/testsuites.html. Note, they released updates to
6 of them in 2025.

  I would say that was a pretty strong statement that, while the US Gov,
was not directly creating a UNIX implementation, they were making sure that
the vendors supplied one.
