HP-32S
The HP-32S was a programmable RPN Scientific Calculator introduced by Hewlett-Packard in 1988 and discontinued in 1991. It continued the tradition of the HP-15C programmable RPN Scientific Calculator. But some functions of the HP-15C were omitted (matrix calculations) and some were reduced in functionality (complex calculations), so to some extent it's more correct to say that the HP-32S rather expanded on the HP-34C. It supported complex math, statistics, probability, etc.
HP-32SII
The HP-32SII added algebraic math, fractions and a second shift key. This was introduced in 1991 and discontinued in 2002.
Sample Program
This is an HP-32Sii version of the Euclidean algorithm to find the greatest common divisor. It is run by entering the two numbers for which the GCD is wanted, and pressing XEQ E.
