Original collection of two vintage Control Data Corporation annual reports, for the years 1969 and 1970. In 1969, the big news was "unbundling" previously bundled hardware and software, a milestone as large as the shift from tubes to transistors, according to the CEO. In 1970, education is the focus, with a network called CYBERNET growing. They are both 8 1/2" x 11" and have 24 pages each. From the estate of one of the founding engineers of Control Data Corporation, who started at Engineering Research Associates after WWII and worked with Seymour Cray. Very good condition. Still crisp. Minor storage wear. A nice piece of computer history and a superb addition to any collection. I ship every day the post office is open with your items safely packed for protection. Please see my store for more museum quality artifacts of history.
