Apollo Computer
     
         A company making {workstations} often used for {CAD}.
     
        From 1980 to 1987, Apollo were the largest manufacturer of
        network {workstations}.  Apollo workstations ran {Aegis}, a
        proprietary {operating system} with a {Posix}-compliant {Unix}
        alternative frontend.  Apollo's networking was particularly
        elegant, among the first to allow {demand paging} over the
        network, and allowing a degree of {network transparency} and
        low {sysadmin}-to-machine ratio that is still unmatched.
     
        Apollo's largest customers were Mentor Graphics (electronic
        design), GM, Ford, Chrysler, and Boeing (mechanical design).
        Apollo was acquired by {Hewlett-Packard} in 1989, and
        gradually closed down over the period 1990-1997.
