The only cray1 left at lanl is serial 2 I am told at least by Cray who shipped it to us when we shipped them serial 1 I have not looked at the actual name plate GAry From: Cynde Moya <CyndeM@livingcomputers.org> Date: Monday, November 12, 2018 at 8:30 AM To: Gary Grider <ggrider@lanl.gov> Cc: members <members@sigcis.org>, "'kwalsh@ucsd.edu'" <kwalsh@ucsd.edu>, "'ianmacconnellsc@gmail.com'" <ianmacconnellsc@gmail.com> Subject: RE: [SIGCIS-Members] Cray 1 serial number 0 being put together on Facebook Live at SC 2018 I was at the Bradbury Museum a year or so ago. They had an exhibit about supercomputing built around a CRAY-1. The front-end staff did not know the serial number. Perhaps this is Serial number 2 you refer to?

When Serial 1 showed up in Los Alamos in 1976 it wouldn’t run for more than a few minutes yet it would run for hours in Minnesota. Turns out there was no memory protection and cosmic events at Los Alamos altitude were different enough from Minnesota. The memory was reworked and protection was added. Serial number 1 was a bit of a testbed and had many mods/corrections made before subsequent machines were produced in 1977 and beyond. That was the intent of the trial.

SCD was oversubscribed; turnaround time had become intolerable. A request for proposal (RFP) was issued, resulting in an order for a CRAY-1A. While serial number 1 of the CRAY-1 computer system had been shipped to the Los Alamos National Laboratory in 1976 for a six-month trial period, NCAR was Cray Research's first official customer. On July 11, 1977, the CRAY-1A, serial number 3, was delivered to NCAR. The system cost was $8.86 million ($7.9 million plus $1 million for the disks).” For a long time, Serial number 1 sat in the Bradbury Museum in Los Alamos until Cray asked if they could have it for their Chippewa<https://www.google.com/search?q=chippewa&spell=1&sa=X&ved=0ahUKEwi9_Iilp8jeAhWFiVQKHTvIBSEQkeECCC8oAA&biw=1125&bih=1215> museum. They shipped Los Alamos Serial number 2 for the Bradbury Museum. I believe it is sitting in a back room at Bradbury now.

Folks in the Dallas area can stop by to see the Cray and supercomputing artifacts assembled for the 30th Anniversary of the SC conference. We will record the fabrication and post a separate time lapse video after completion.
