The 1101 computer, was originally known as the Atlas and was designed for military applications.
Frank Mullaney, the first Chairman of the Board for Cray Research, was a design engineer for this machine. |
| 1952 |
ERA was acquired by Remington Rand in 1952 and became the Military Division of Remington Rand Univac. |
| 1953 |
The first machine that many of Cray Research’s founders worked on was the UNIVAC 1103 scientific computer designed by ERA.
The 1103 computer weighed about 14 tons, and the mainframe occupied 612 sq ft.
The first few 1103 computers used vacuum tube memory; ferrite core technology was applied to later models.
Five wires went through each core in the matrix. |

In 1955, the Sperry Corporation merged with Remington Rand forming Sperry Univac. |

| 1962 |
The CDC 160A computer was announced and sold for $500,000. |
| 1964 |
|
| 1969 |
The CDC 7600 was announced in 1969. It was sold to many of the same customers as the 6000 series machines.
|
| 1970 |
Serial No. 3 was assembled in Chippewa Falls and shipped to the Los Alamos Scientific Laboratory for use in nuclear research. |
| 1972 |
Former CDC founders Seymour Cray, Frank Mullaney, George Hanson, and Noel Stone, formed Cray Research.
The new company, which established its headquarters in Chippewa Falls, began its operations with engineering teams headed by Les Davis, Dean Roush, and Harry Runke. |
| 1976 |
Serial No. 1 of the Cray-1 computer system, the company’s first product, was powered and officially introduced.
The National Center for Atmospheric Research NCAR was Cray Research’s first official customer. |
| 1982 |
In September of 1982, the CRAY-1M system, the last Cray-1 series of computer systems was announced.
Only nine CRAY-1M systems were built before they were replaced in the product line by single processor CRAY X-MP systems, which featured the same high performance CPU as the rest of the CRAY X-MP series.
Cray Research announced the CRAY X-MP, its first multiprocessor computer. With their 9.5 ns clocks, the two CPUs for the CRAY X-MP system were significantly faster than those for the CRAY-1 system. The IOS, having proven its worth, became a standard feature. |
| 1985 |
|
| 1988 |
The CRAY X-MP series of computer systems was one of Cray Research’s most popular products to date, with 189 produced.
Operating systems used on CRAY X-MP systems include COS; CTSS (The Cray Time-Sharing System developed by customers at the Lawrence Livermore Laboratory and the Los Alamos National Laboratory), and UNICOS based on UNIX System V technology. |
| 1989 |
Cray formed Cray Computer Corporation (CCC) in Colorado Springs, Colorado |
| 1993 |
Cray 3 project canceled |
| 1994 |
Cray Computer Corp releases the Cray-4 |
