Ideal for real estate, finance and business professionals, the HP 17bII+ features a simple keyboard, 250 menu-driven functions, RPN1 and algebraic entry-system logic.

Its intelligent menu system allows you to concentrate on the problem, not on the calculator. It uses the second line of the screen to display the functions of the upper row of keys, adapted to your needs through built-in menus or user-supplied formulae.

After more than 20 years and 3 versions with different processors, its unsurpassed function set and user friendliness keeps the HP17bII in the to echelon of financial calculators.

The HP-12C is HP's longest and best-selling product, in continual production since its introduction in 1981. Due to its simple operation for key financial calculations, the calculator long ago became the de facto standard among financial professionals – for example, most investment banks issue HP-12Cs to the members of each incoming class of its investment banking analysts and associates.

In 2008, HP modified the design so that new production runs contain an ARM processor which runs an emulated version of previous chips. This has brought advanced possibilities such as flashing new firmware, not previously possible. HP also released a software development kit (SDK), making it possible to make new and custom operating systems. The calculator runs 20 times faster on most benchmark operations. This version is colloquially known as the HP-12C+ although HP does not market it as a different product. This is the version sold by TheCalculatorStore.com.

Original HP17bII calculator. Excellent state. Original cover. Works with both Algebraic and RPN

This calculator was the intermediate step between the current HP 17bII and the old, Pioneer-style HP 17bII. Main differences with the original are increased memory (up to 28 kb), and the currency exchange menu. There is as well the "key feel": while both have good tactile feedback and never miss a key, some called "hollow" the keyboard touch of the 17bII+

The calculator is in perfect shape, with some dust specs in the screen (already there when I bought it). However, the pouch is a little bit "battered" - see enclosed pictures.
