dinosaur n.

1. Any hardware requiring raised flooring and
special power. Used especially of old minis 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 mainframe.
2. [IBM] A very conservative user; a zipperhead.
