Cray supercomputer

In 1977, the first Freon-cooled Cray-1 supercomputer, costing $19,000,000, was shipped to Los Alamos Laboratories, NM, and was used to help the defense industry create sophisticated weapons systems. This system had a peak performance of 133 megaflops and used the newest technology, integrated circuits and vector register technology. The Cray-1 looked like no other computer before or since. It was a cylindrical machine 7 feet tall and 9 feet in diameter, weighed 30 tons and required its own electrical substation to provide it with power (an electric bill around $35,000/month). The inventor, Seymour Cray, died 5 Oct 1996 in an auto accident. His innovations included vector register technology, cooling technologies, and magnetic amplifiers.
