Stone Age In computer folklore, an ill-defined period from ENIAC (ca. 1943) to the mid-1950s; the great age of electromechanical dinosaurs.
Bronze Age ‘Bronze Age’ era of transistor-logic, pre-ferrite-core machines with drum or CRT mass storage (as opposed to just mercury delay lines and/or relays).
Iron Age 1961-1971 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.
Elder Days The heroic age of hackerdom (roughly, pre-1980); the era of the PDP-10, TECO, ITS, and the ARPANET. This term has been rather consciously adopted from J. R. R. Tolkien's fantasy epic The Lord of the Rings.
