Hello once again everyone, I am proud to announce the publication of a
number of documents scanned by Stephen Searle from his large collection
of UNIX Support Group (USG) library documents from the 70s and 80s.
Stephen worked under Ted Kowalski at Murray Hill and and then later at
Piscataway, becoming friends with the technical librarian who then
provided these and other documents.

Among these documents is #1100, the UNIX Bibliography as maintained by
USG.  This lists out references to the other documents in this
collection as well as the USG library numbers for other known and
unknown documents.  Even better, two revisions of the bibliography are
present, as well as a number of other papers detailing the documentation
efforts of systems such as Program Generic Issues 1 and 2, UNIX/TS, and
PWB 2.0.  All in all, much light is shed on early USG UNIX prior to
System III.  In addition, there are documents concerning BTLs
microprocessor efforts, including use of Intellec MDS units, a MAC-8
software simulator, and the application of the IS25 assembly language
to the MAC-80/BellMAC-32 project.
