Minicomputers were supposed to kill the mainframe. They are gone. Digital Equipment Corporation and Data General are dead. The last minicomputers were IBM's AS/400 line, renamed to System i, then merged with the Power Systems . IBM's victory over the minicomputer is so total that people seldom even use the word “minicomputer,” anymore. Nowadays, the preferred word is “midrange computer,” a term coined by the mainframe maker, IBM.
