The HP-32S (code-named "Leonardo") was a scientific calculator utilizing RPN that Hewlett-Packard introduced in 1988. This model was eventually replaced by the HP-32SII.

HP-32SII

Launched in 1991 and manufactured until 2002, the HP 32sII improved upon its predecessor by incorporating a second shift key, which allowed quicker function access, along with fraction support activated through pressing the decimal key twice. The solver functionality transitioned from RPN to algebraic input. Initially, the device sported an orange and blue color scheme reminiscent of the HP 32s and HP 48SX models; however, in 1999, the shift key colors were revised to dark green and lilac.

Thanks to its enhanced capabilities and operational speed, the HP 32sII became a favored option for Texas UIL calculator contests, underscoring its popularity within the scientific calculator market.
