A colour-printed, illustrated 24-page brochure for the Cray-1, a supercomputer designed, manufactured, and marketed by Cray Research. The first Cray-1 system was installed at Los Alamos National Laboratory in 1976, and it went on to become one of the best known and most successful supercomputers in history. The Cray-1's architect was Seymour Cray and the chief engineer was Cray Research co-founder Lester Davis.

This was the first Cray design to use integrated circuits (ICs). Although ICs had been available since the 1960s, it was only in the early 1970s that they reached the performance necessary for high-speed applications. The Cray-1 used only four different IC types, an ECL dual 5-4 NOR gate (one 5-input, and one 4-input, each with differential output), another slower MECL 10K 5-4 NOR gate used for address fanout, a 16×4-bit high speed (6 ns) static RAM (SRAM) used for registers, and a 1,024×1-bit 50 ns SRAM used for the main memory.[4] These integrated circuits were supplied by Fairchild Semiconductor and Motorola. In all, the Cray-1 contained about 200,000 gates.
