The '''HP-32S''' (codenamed "Leonardo") was a programmable [[Reverse Polish notation|RPN]] Scientific [[Calculator]] introduced by [[Hewlett-Packard]] in 1988 and discontinued in 1991. It continued the tradition of the [[HP-15C]] programmable [[Reverse Polish Notation|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 is more correct to say that the '''HP-32S''' expanded upon the [[HP-34C]]. It supported complex math, [[statistics]], [[probability]], and other functions.

The '''HP-32SII''' (codenamed "Nardo") added algebraic math, fractions, equations (from the [[HP-22S]]) and a second shift key. The calcultor was introduced in 1991 and discontinued in 2002. The original color scheme was blue and yellow, which was changed to green and violett in 1999.

In 2022, [[SwissMicros]] released pre-production samples of an RPN calculator called ''DM32'' running a version of their DMCP operating system programmed to resemble the HP-32SII. Even though slightly smaller (144×77×12&nbsp;mm, 180&nbsp;g) than the original HP-32S (148×80×15&nbsp;mm, 170&nbsp;g) the calculator comes with an additional top row of keys for soft menus, an improved tactility of the keyboard (compared to the [[DM42]] keyboard), a blue/yellow color scheme, a much larger high-contrast display ([[Sharp Corporation|Sharp]] low power transflective memory [[LCD]] with a resolution of 400×240, protected by [[Gorilla Glass]]) showing all four stack levels at once (configurable), ca. 256&nbsp;KB usable RAM, a beeper, a callable [[real-time clock]] as well as an infrared port for [[HP 82240A]]/[[HP 82240B]] printer support and a [[USB]] interface (with [[USB-C]] connector) emulating a [[FAT16]]-formatted USB mass storage device for easy program transfer and state backup&nbsp;/ transfer as well as for firmware updates. The calculator, which comes in a stainless steel case with matte black [[physical vapor deposition]] (PVD) coating, supports keyboard overlays and uses [[Intel]]'s decimal floating-point math library for higher precision ([[decimal128]]) running on an [[STM32U575RIT6Q]] processor ([[ARM architecture|ARM]] [[Cortex-M33]] core, 768&nbsp;KB RAM, 2&nbsp;MB internal flash) with another 8&nbsp;MB of external QSPI flash (of which ca. 6&nbsp;MB are available to users). It is powered by a [[CR2032]] coin cell or via USB and clocked dynamically at 48–160&nbsp;MHz. The DM32 incorporates a multi-state facility allowing to save, restore and switch between multiple states of the calculator like in a [[task switcher]] or with multiple "virtual" calculators.

A project based on the ''DM32'' hardware is [[Christophe de Dinechin]]'s [[DB48X]] (2022) to recreate an [[RPL (programming language)|RPL]] environment from scratch.
