During the mid-1970s, the United States Department of Defense became
interested in the opportunity to combine a microprocessor, a flat screen,
and communications technologies into a mobile communications unit. The SAIC
Corporation, founded by Dr. J. Robert Beyster, became a key participant in
producing early systems of this type. The GRiD Severe Environment and
TEMPEST (GRiDSET 1177) military laptop was produced by SAIC in
collaboration with GRiD Systems, the designer of the first commercial
laptop computer. The unit shown here was donated by Dr. Beyster’s family to
his alma mater, the University of Michigan.
