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… 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.
