Livermore Data Systems modems that I sold off were from about 1964?

Did you have anything to ascertain the 1964 date for LDS, or were you getting that date
from the stuff on the web?
. . .
Someone in some comments suggests LDS wasn't
building these until 1968, which strikes me as more plausible.
That is why I put a question mark after 1964.
I was basing it on nothing more than verbal comment by the guy that I got them from.
And, while I had them, I hadn't had any reason to particularly care.
1968 does, indeed, seem more plausible.
It still serves to illustrate that 1971 is NOT too early for that NCR.

I can add another data point to the discussion:
My LDS Model A with SN 0491 has two TI transistors both with data code "6914"
And for what it's worth, if you have one and have never opened it up, go do so right
now! The three small circuit boards have a 3"x4" piece of the infamous black
foam to pad the cards when inserted in the case. Of course the foam is mostly gone now
except for where it wraps around the cards and corrodes the components that it touches!
