In the history of computing, the Iron Age was a period from about 1961 to 1971 — the formative era of commercial mainframe technology, when ferrite-core (core memory) dinosaurs 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.
