In early 1972, Cray and six other colleagues left CDC to form Cray Research. Les Davis was a co-founding chief engineer and is often credited with Cray’s success. Their relationship was characterized by one engineer: “When Seymour tosses designs out the window, Les catches them”.
It was time to use Integrated Circuits.
