National Semiconductor actually made calculators back
in the 1970s - I
Weren't 'Novus' related to National Semiconductor? The Novus line of
calculators is farily well-known (if only because there was at least one
RPN model).
I also rememebr reading about their calculator chips in one of their
databooks (I don't have the right databook, I think it was shown in an
application schematic for a display driver chip).
used to have one maybe 20 years ago, but it is long
gone. They also
made a line of plug compatible S/370 mainframes, as well.
And add-on memory for PDP11s, etc
