This interesting TV Program from 1987 The Computer Chronicles – Super Computers Episode Has information about NASA Ames Cray-2 and Los Alamos C1 & XMP. Shows the systems in there working environment along with explanations as to how the Cray systems are advancing science. About 30 Minutes – First part on NAS Ames Cray 2 then onto
The HASE Cray-1 Simulation Model is available here “Simulation models of a variety of computer architectures and architectural components have been created using HASE, a Hierarchical Computer Architecture design and Simulation Environment. These models are intended for use as teaching and learning resources: in lectures, for student self-learning or for virtual laboratory experiments. Using the models requires

After seeing these pictures that seem to have the wire-mat showing on the module side of the frame I asked Sonja about the Cray-1 construction process: Sonja’s Story A little history you might already know: Seymour Cray was working for Control Data. I believe he wanted to build ‘his’ computer but CDC was going in

Fifty years of Cray supercomputers was celebrated with a virtual tour hosted by TNMOC in UK on 6th April 2022 This virtual talk explored the physical and logical structure of Cray-1 SN34, peaking ‘under the covers’ of this remarkable machine. The talk also illuminates how these machines evolved and sample some of what was achieved

The first of a kind always holds special interest for historians and serial number one, the first Cray-1 computer system is no exception. Made in 1976 this machine, really just the prototype but proved it’s worth at 6 sites paving the way for early sales of Cray Research Supercomputers. Serial Number 1 World Traveller From Cray
