Sharing another tranche of documents I've scanned recently:

https://archive.org/details/am-2900-bipolar-microprocessor-family-1975-06

This is the earliest Am2900 databook from what I know, before I could go
as far back as 1977.  The Am2901 is of interest to me as the processing
slice combined to make the core of the WECo 3B computer.

https://archive.org/details/rca-integrated-circuits-product-guide-june-1968
https://archive.org/details/rca-integrated-circuits-new-product-news-august-1968

These two RCA guides include the introduction of the COS/MOS CD4000 line
of CMOS digital logic.  The former still contains all such silicon by
"TA" development codes.  All but one (as hinted at by footnotes) is then
given by its final CD4* designation in the later issue.  Unfortunately
no datasheets are present in this literature, but pricing info is given
for early CD4000 and a few other families in the August, 1968 guide.

https://archive.org/details/rca-cos-mos-product-guide-march-1971

These are then RCA COS/MOS guides from a few years later.  The March
issue in particular seems to both introduce the purple accenting that
would become synonymous with COS/MOS and also the "CD4000A" series
featuring tolerances as low as +3Vcc.  I scanned both in color to show
the contrast between just a few months.  The black and red speaks a bit
more to my personal sensibilities, but it didn't seem to last long.
However, I have to wonder if black and red was ultimately abandoned due
to its being so common in RCA imagery already by that time.

Regarding RCA, I do have in the mail two red binders of many RCA
component datasheets from the late 60s.  I suspect '68 or '69.  In any
case the auction didn't have enough photos to tell if CD4000 (or TA*)
stuff was present, we'll see.

This one I was particularly excited to come across.  This is a 1972
guide from Western Electric detailing various solid state devices
available for design engineers.  Among them are the linear and digital
IC families 41* and 502*.  These guides are not databooks in that they
do not contain complete datasheets.  However, pinouts and some data are
given.  These and newer chips are then documented in the 1973 and onward
Silicon Integrated Circuits manuals.  I have a smattering of this stuff
I intend to scan as well, but just haven't yet.

Anywho, the next stuff I'm scanning is more UNIX oriented so will hit
the TUHS list instead.

P.S. I've been turning a focus to historic IC literature of all kinds
lately, if you have any early literature, especially '64-'65 Ti54/74 and
'68-'69 RCA COS/MOS stuff, I'd be happy to arrange scanning operations.
