[TUHS] More Lost BTL UNIX Literature Procured

[segaloco via TUHS]

Howdy folks, I've got some exciting news for UNIX document preservation.
I just closed this purchase:

https://www.ebay.com/itm/147235873077

After the link is an auction for several original BTL UNIX manuals and
technical memoranda, including:

Documents for UNIX - Sixth Edition
Seventh Edition Volume 2A/2B
UNIX Product Release Description - Release 4.0
Program Generic PG-1C300 Issue 3 
UNIX Release 4.0 Release Notes Package
Several Technical Memoranda

For me the most exciting parts are the Release 4.0 material and the
Program Generic Issue 3 manual.  This all should be arriving in a week
or two, at which point I'll bump it to the top of my scan list (right
under the SVR2 BTL manual I'm halfway through right now).

More to come!

Also, the seller also has original print BBN UNIX literature, I
expressed no personal interest as I'm keeping focused on BTL and UCB,
but I'll share when that auction is posted as they seem like quite rare
pieces someone here might be interested in.
