Cray soon left the CEO position to become an independent contractor. He started a new Very Large Scale Integration technology lab for the Cray-2 in Boulder, Colorado, Cray Laboratories, in 1979, which closed in 1982; undaunted, Cray later headed a similar spin-off in 1989, Cray Computer Corporation (CCC) in Colorado Springs, Colorado, where he worked on the Cray-3 project—the first attempt at major use of gallium arsenide (GaAs) semiconductors in computing. However, the changing political climate (collapse of the Warsaw Pact and the end of the Cold War) resulted in poor sales prospects. Ultimately, only one Cray-3 was delivered, and a number of follow-on designs were never completed. The company filed for bankruptcy in 1995. CCC's remains then became Cray's final corporation, SRC Computers, Inc.
