Link: The Unix Heritage Society now has the 8th, 9th, and 10th editions of Research Unix
Today in an email message with the subject of [TUHS] Release of 8th, 9th and 10th Editions Unix, Warren Toomey announced that the Unix Heritage Society has now gained permission to make the source code of Research Unix's 8th, 9th, and 10th editions available for the usual non-commercial purposes. This apparently is the result of a significant lobbying campaign from a variety of Unix luminaries. The actual source trees can be found in TUHS' archive area for Research distributions.
Most people are familiar with Research Unix versions through V7
(the 7th Edition), which was the famous one that really got out
into the outside world and started the Unix revolution. The 8th
through 10th editions were what happened inside Bell Labs after
this (with a trip through BSD for the port to Vaxen, among other
things; see the history of Unix), and because Unix
was starting to be commercialized around when they were being worked
on by Bell Labs, they were never released in the way that the 7th
Edition was. Despite that they were the foundation of some significant
innovations, such as the original Streams and
/proc, and for various
reasons they acquired a somewhat legendary status as the last
versions of the true original strain of Research Unix. Which
you couldn't see or run, which just added to the allure.
You probably still can't actually run these editions, unless you want to engage in extensive hardware archaeology and system (re)construction. But at least the Unix community now has these pieces of history.
