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.
