Comments This is the new model with silver bezel around the display and green/purple key coloring scheme. It is said to be of lower quality. The "feeling" of the keyboard is nevertheless very good! The printing on the top of the keys is sometimes off-center, though (see S+ key for example).

Comment The HP-32S is a very powerful calculator that brings many features of the HP-15C to the Pioneer platform. Among them the solver and numerical integrator. However, the implementation of complex numbers is not quite as seamless as in the HP-15C. It also introduces the concept of named variables and labels with a single letter instead of numbers. It uses only one prefix key and provides most functions thru menus. Thanks to the low-resolution graphical display that allows to show not only numbers but also text the menus are easy to use.
The HP-32SII is HP's last Pioneer model (assuming the HP-10BII isn't really a Pioneer). This one is another candidate for "best calculator ever". Compared to its close relative the HP-32S the main added features are support for fractions and equations but this comes at the price of a more cluttered keyboard with two prefix keys. Different from the HP-27S its menu structure is straight-forward and easy to use - maybe because it uses RPN and passes arguments on the stack. Includes a wealth of built-in functions comparable to the HP-15C. The sophisticated support for fractions is pretty unique even among other HP calculators (at least at that time). Successors to the HP-32SII were the HP-33s and HP-35s.
There was a 50th Anniversary Limited Edition version of the HP-32S similar to the HP-14B.
