NCR Corporation
     
         Electronics company mainly active in the midrange
        server market.
     
        NCR was founded 1884 as National Cash Register Company.  It
        joint the computer industry in th 1950s.  In 1991 it was
        absorbed by {AT&T} (see {dinosaurs mating}), only to be spat
        out again in 1996.
     
        NCR {mainframes} of the 1960's are remembered by some for
        their hardware incompatibility with {IBM} mainframes: NCR
        punched round holes in their {punched cards} while IBM punched
        rectangular ones.  The codes and machines were not compatible
        and information could not be easily shared between NCR and IBM
        customers.
