The HP-32S (internally known as "Leonardo") was a scientific calculator featuring programmable RPN functionality, introduced by Hewlett-Packard in 1988. Its design was later refined and succeeded by the HP-32SII model.
HP-32SII
Released in 1991 and manufactured until 2002, the HP-32SII built upon its predecessor’s capabilities by incorporating a second shift key, enabling quicker access to functions, as well as support for fractions through a double press of the decimal key. Additionally, the solver system transitioned from RPN to algebraic input, enhancing overall ease of use. The original orange and blue color scheme for the shift keys was replaced in 1999 with a dark green and lilac palette.
These enhancements contributed to the HP-32SII's widespread adoption in competitive settings such as the Texas UIL calculator competitions, solidifying its reputation as a favored scientific calculator among both professionals and students.
