[TUHS] Research Ninth Edition Manual (V1) Found

[segaloco via TUHS]

Exciting news, I managed to run down a physical copy of volume one of
the Ninth Edition Programmer's Manual.  I don't think any version of
this is currently preserved, so I'll try and get it on my scan docket
once I've got my new RISC-V machine all stable.  Unfortunately it is
just volume one, although given the relative lack of distribution, I
wouldn't be surprised if volume two wasn't physically published, but I
can't rule that out entirely.

Anywho, it is thicker than the Tenth Edition I've also got sitting here,
but I haven't had a chance to thumb through the indices to get a feel
for what the delta is.  An exciting find nonetheless!

In the meantime until I get this scanned, happy to entertain any
questions on contents.  A question myself:

What would the reach of V9 have materially been in the late 80s vs. V8
and V10 around it?  The only artifacts from V9 I'm aware of are
contained in the archive from the batterpudding collection. It seems V9
is pretty darn obscure in the grand scheme of things, so I find myself
curious what the likelihood of something a little closer to virgin BTL
tapes popping up actually is vs. trying to get hands on backup tapes or
images from running systems being used in BTL between 86-89.
