Crays at Linkoping used by Saab in Sweden and NSC

The series of Cray systems that went to Sweden started with Cray-1 SN9 later to be replaced by XMP SN206 and others. Unusually the system was shared between The University at Linkoping and Saab-Scania using the Multi Level Security features of Unicos. Work on Jets, cars and trucks was completed. from Auto Week in 1987

3D Models YMP-D and Cray-2

Toby Harness  reports –  I released detailed YMP and Cray-2 3D model plans on Thingiverse.com The YMP can run a full emulator, booting UNICOS (by Modular Circuits/The Cray Files). The Cray 2 doesn’t have an emulator, but does have a floodable tank option, with an air or water pump for bubbles (this option is still

Cray Inc Vision and Roadmaps for product development 2000 .. 2010

A few product development roadmaps as they changed over time from 2000 t0 2010. Comment: Back in the early days Cray Research had multiple lines of somewhat competing vector computing products Cray-2 & XMP then later the C90 & Cray-3.  At other times Cray was transitioning from one type of computing to another due to
