That however, is far different from systems that were bit serial as that
was done to reduce the number of redundant logic elements needed (at the
expense of speed) and often these serial machines had very long
instruction and data words with 31bits not unheard of.
Ray Holt's F14 microprocessor was serial to cut down on component count.
