Code named "Nardo", HP 32SII is considered a further cost-reduced version of HP 32S. It was introduced on the 1st March 1991, and discontinued by September 2002 (until NEC was unable to continue manufacture of Saturn architecture chip). Instead of the elaborate silicon-on-sapphire exposed-die chip held down by plastic, it switched to a more conventional looking plastic wrapped chip design. It is believed the architecture remained the same otherwise. All HP32SII had the later variant | Code named "Nardo", HP 32SII is considered a further cost-reduced version of HP 32S.

Instead of the elaborate silicon-on-sapphire exposed-die chip held down by plastic, it switched to a more conventional looking plastic wrapped chip design. It is believed the architecture remained the same otherwise. All HP32SII had the later variant LCD as standard. | |||
The 32SII replaced the Up and Down keys on HP32 with Left and Right shifts respectively, bringing much of the menu driven functions to top level, giving it the cluttered keypad look. Two revisions of HP32SII exists with different color scheme. Before 1999 HP 32SII had standard pioneer brown plastic with brown bezel and yellow-blue shifted legends (as seen on the manual). After 1999 this was changed to a white painted bezel (like later HP 17BII) with green-blue shifted legends. | |||
Notably, the HP 32SII added a new "EQN" or equation environment to the machine which supports (and only allows) algebraic logic entry of formulas, with support for bracketed expressions and equivalence, much like that present on the HP 17B series. Solver can be invoked by opening the Equation menu and selecting the desired equation. EQN can also be programmed and Flag 10 can be set to disable EQN validation, using it to display messages instead. However as the memory was not expanded, it suffers the same problems as its predecessor if not more. | |||
The solver can still be used on RPN programs. | |||
