HP-22S

Hewlett-Packard HP-22S (1989)

The HP-22S is an electronic calculator from the Hewlett-Packard company which is algebraic and scientific. This calculator is comparable to the HP-32S. A solver was included instead of programming. It suffered from the same constraints as the 32S since it lacked enough RAM for serious use. Functions available include TVM and unit conversions. Only single letter variable names are allowed.
