Atanasoff and Berry did a GREAT job, but it wasn't actually
a "computer" by
the Turing definition. It took instructions from cards and
executed them as
they were read on the card reader. I think it may have had
some ability
to suppress instructions on some condition, but couldn't
actually do a branch.
Then, after completing the calculation the built it for, the
university junked it and
all that was left were some drawings in a few binders. They
published NOTHING
about the machine itself, and it was largely unknown for
DECADES!
They probably could have advanced some areas of computing if
they had
published the technical details of their machine. It was
pretty obvious that
if they had actually needed a stored program computer with
branching
ability, they were sharp enough they could have built such a
machine, but they
just didn't need it for the class of equations they were
solving.
So, as far as I'm concerned, Atanasoff and Berry are a VERY
interesting footnote
in early computing, but didn't actually contribute directly
to the development
of computers. Atanasoff sure upset some people when he
testified in
the Honeywell vs. Sperry Rand suit.
Now, my freshman adviser at Washington University was
William Papian,
the grad student who worked with Jay Forrester on coincident
current
core memory! Wow, talk about something that REALLY affected the
development of computers!
