The photo shows Seymour Cray with his wife and colleagues during their visit to the Laboratory in Sept'1979.
Some more pictures of the Cray-1 at Daresbury in 1979.
Some boards from this machine are shown on Jim Austin's Computer Museum Web site. Pictures as it now is, preserved in the Chippawa Falls Cray Museum are shown on the Cray Wiki.
This Cray-1 SN1 travelled the world and spent several years in the UK. The early part of the story is told in Cray Channels magazine, vol 1: issue 3. We are trying to find the precise dates, so far as follows.
SN1 was on loan from Cray Research Inc. and installed at Daresbury following an agreement between the Science Research Council at the time and Cray UK. 30% of the time was rented by SRC for scientists and the remaining time dedicated to other potential Cray customers. There had been considerable pressure to buy a British computer, such as the ICL DAP (one was installed at Queen Mary College, London) but it was believed that the Cray was more appropriate to the current requirements and the arrangement allowed this to be proven.
It actually spent quite a lot of time traversing the Atlantic around the dates mentioned above. These machines were so far ahead of their time that many of them worked at a number of sites, sometimes being leased for short periods until the customer's own ordered machine was ready. Agreement had been reached on 11/5/1979 to lease a machine from Cray Research Inc.
By the end of 1980 the Cray-1 with 0.5M words of main memory and 1.2GB disk storage had been replaced by a Cray-1S with 1M words. This machine was a 1S/1000 (formerly a 1S/500) leased by Cray Research Inc. to Daresbury until 1983. We believe this was Cray-1S SN28. It is possible that there was a Cray-1A before this.
Some pictures of the Cray-1 during dis-assembly in 1980.
The following table lists the known working locations of some of the early Cray-1 machines. There were less than 80 Cray-1 machines built with serial numbers SN01-SN8x. Around twelve were installed world wide by Sept'1977. Lawrence Livermore had a total of four Cray 1s over a number of years. We would like to thank Jean de la Taille for contributing to this information.
It was noted on 26/11/1981 that there were they five Crays in the UK: MoD (Aldermaston); SERC (Daresbury); the oil industry (Shell, Wythenshawe); European Weather Centre; and for atomic energy research (AERE Harwell). Cray-1A SN11 at AWE Aldermaston ran from 1979-1990. It was the last operating Cray-1 in the world and is now preserved in the London science museum (accession number 1991-159).
