Before Control Data, there was Engineering Research Associates (ERA) in Minneapolis, building the ERA 1103 computer. Here is where Seymour Cray started to work designing computers. (always click to get the large version)


History of Control Data

The history of Control Data (CDC) is of course quite nicely described in the Wikipedia. I (the author of this site) had started to work at CDC in Frankfurt in 1976, after working at the CDC 3300 at the University in Giessen since 1972.

During my time at CDC, I have collected a number of artifacts that I have scanned in (well, only those on paper, actually, not the core memory modules and other "hard artifacts").

June 2010: YouTube-movie about Plato-History, the first large scale computer-based training effort, with many references to CDC and the history of social computing and the development of all the things we now are very familiar with: e-mail, chat rooms, discussion forums, multi-user games, synthetic speech generation.

Einen sehr umfassenden Überblick (auch über CDC) bietet dieser Vortrag von Gordon Bell My perspectives on Seymour Cray's contributions to Computing.

(Von Gordon Bell gibt es übrigens eine große Zahl von Vorträgen.)

In 1997 the employee magazine Contact brought a 11-page article The Early Years

In 1991, after German Reunification, a 1604 was found in working condition. Here the article in Contact (pdf).
