Cray supercomputers have shown up in popular culture, sometimes mentioning a specific machine type other times just using “Cray Computer” in a generic sense. Listed here are some references to Cray systems in popular culture. Let us know if you know more. Books Jurassic park – Mentioned in the Michael Critchton book but a Connection …
Correspondent Kevin Smith reports from FB Hi Clive, I went down in the basement and dug around in my “CRI museum” and pulled out a few things. So, SN2004 and SN2005 were covered under SS-12 and SS-18 for our customer. SN2004 was RED/WHITE/BLUE while SN2005 was a shade of Brown ( see pics). Do not …
This large tech museum in Padaborn Germany has SN2o18 Cray-2 on display. Editor note: SN2018 is currently listed as having previously worked at National Energy Research Supercomputer Center (NERSC) @ Lawrence Berkeley Livermore Labratory and Internal machine at Cray Research, Inc (CRI). Not sure how it ended up in Europe unless it did some time at another undisclosed …

From about 1987 to 1997, it was traditional that Cray Research would ship a customer system book showing images from the factory of how the system was built. Included in the book, were pictures of the staff and machines that built the customers machine. A couple of examples of the system book have been captured …
If you look closely into the top of a Cray-2 we are able to make out rows of indicator lights that were used by service engineers to assess the state of a machine. In the event that a machine hung or unexpectedly halted, the indicator lights were examined to gain some idea of what was …
