19 Jears to late - Pascals machine is dated 1942.
But thinking again, we should define what a 'calulatoer'
is for our search of the first one - Right now I prefer
the definition of a macanic machine to add and subtract
numbers, displayed in (decimal) digits by pointers or
similar, without restrictions to special numbers. This
excludes analogous calculators and special purpose thingis.
