In the history of computing, 1961-1971 -- the formative era of
commercial {mainframe} technology, when ferrite-core {dinosaur}s
ruled the earth. The Iron Age began, ironically enough, with the
delivery of the first minicomputer (the PDP-1) and ended with the
introduction of the first commercial microprocessor (the Intel 4004)
in 1971. See also {Stone Age}; compare {elder days}.
