Were those the Livermore Data Systems modems in a wood box you were selling?
Did you have anything to ascertain the 1964 date for LDS, or were you getting
that date from the stuff on the web?
There's stuff reffed all over the web and youtube of some guy stating the LDS
Model A (in the dovetailed wood box) as 1964 and maybe 1963, his unit is serial
# 279.
http://www.phreakmonkey.com/2009/05/1964-livermore-data-systems-model-modem_31.html
etc.
He seems to be basing the claim on an LDS Model B unit (once at UCDavis, now at
CHM)
http://www.computerhistory.org/collections/catalog/102630200
which claims circa 1965, and 'thus the model A should be at least a year
earlier'.
I have an LDS Model A, serial # 858, the dates codes on the components are 1969
to 1970.
I'm a little skeptical the model was being made as early as 1964.
I wish the guy would, or knew to, simply open the unit and look at the date
codes rather than guessing.
Someone in some comments suggests LDS wasn't building these until 1968, which
strikes me as more plausible.
