For more than 20 years I'm working with the HP-32SII, a fantastic RPN calculator. Although this calculator still works fine, I started looking for a spare. During my search I discovered a lot of interesting calculators.

Early 2006 I started to collect Hewlett Packard pocket calculators. For the time being my collection of handheld calculators is restricted to all models from Hewlett Packard and RPN models from other brands.



This web site is my personal attempt to a structured storage of a lot of information and links that I gathered along the years. It gives a nice overview of my collection and a lot of additional information about HP pocket calculators in general.

The collection has been categorized according the HP model series. Make your choice

by using the menu bar on the left. More general information about the hardware and software

can be accessed by the other menu items.

If you have a contribution to my collection, please feel free to contact
