RE: First calculator handling fractions
I *believe* the first HP that could natively work with fractions was the HP-32SII which was introduced in 1991.

Note that the HP-48SX introduced a year earlier had the ->Q function which could convert a real number to a fractional algebraic expression. I don't consider this a native support of fractional entry and display as we are discussing here.
