dinosaurs mating

dinosaurs mating n.  Said to occur when yet another {big
   iron} merger or buyout occurs; reflects a perception by hackers
   that these signal another stage in the long, slow dying of the
   {mainframe} industry.  In its glory days of the 1960s, it was
   `IBM and the Seven Dwarves': Burroughs, Control Data, General
   Electric, Honeywell, NCR, RCA, and Univac.  RCA and GE sold out
   early, and it was `IBM and the Bunch' (Burroughs, Univac, NCR,
   Control Data, and Honeywell) for a while.  Honeywell was bought out
   by Bull; Burroughs merged with Univac to form Unisys (in 1984 ---
   this was when the phrase `dinosaurs mating' was coined); and in
   1991 AT&T absorbed NCR.  More such earth-shaking unions of doomed
   giants seem inevitable.
