dinosaur

1. Any hardware requiring raised flooring and special power.

Used especially of old minicomputers and mainframes, in

contrast with newer microprocessor-based machines.

In a famous quote from the 1988 Unix EXPO, Bill Joy compared

the liquid-cooled mainframe in the massive IBM display with

a grazing dinosaur "with a truck outside pumping its bodily

fluids through it". IBM was not amused.

Compare big iron; see also dinosaurs mating.

2. [IBM] A very conservative user; a zipperhead.
