What was it like building early Cray systems ?
Read this personal account by Sonja Gardener of her time assembling early Cray supercomputer systems.
What was it like servicing and repairing complex Cray systems ?
Read this personal account by Charlie Clark of his time as field engineering manager at Cray .
Early in March 2023 had a couple of days at the Computer Museum of America in Atlanta. Took the opportunity to wander round and make some mini-videos of some of the Cray Supercomputer exhibits. See the collection here.
Thanks to Lonnie and David Laufer Creative director at CMoA for the titles and opportunity.
Research the Cray Channels magazine, the premier source for information about Cray Research systems, customers and applications.
