CRAY, SEYMOUR. 1925-1996.
ORIGINAL CRAY 3 MODULE
Original module consisting of 4 layers of 16 sub-modules, with 45 female connectors and 4 metal power connects, about 130 x 135 mm overall, in original black plastic case labeled "DO34."
The Cray 3 was the first offering of the Cray Computer Corporation, Seymour Cray's spin-off from Cray Research, Inc., the company that he created in 1972 after he left Control Data Corporation. The Cray 3 was the first supercomputer to use gallium arsenide integrated circuits for all of its logic circuitry and was the fastest computer of its time. The changing political climate at the end of the cold war drastically shrank the supercomputer market and much of the market turned to massively parallel designs. Cray ended up loaning a Cray 3 to the National Center for Atmospheric Research (NCAR) and another government order the company received was cancelled.
