"In spite of the large number of computing systems which have been de-
signed and are in use today there is no clear-cut optimum approach to a gen
eral purpose computing system. Rather, it would seem, we are just begin-
ning to explore the really basic variations from the one address sequential
machines that launched the digital computing industry.
.
.
.
System design then began to diverge into parallel structures. This
book describes one of the early machines attempting to explore parallelism
in electrical structure without abandoning the serial structure of the com-
puter programs. Yet to be explored are parallel machines with wholly new
programming philosophies in which serial execution of a single program is
abandoned.
