My Hewlett Packard calculator collection

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

Early 2006 I started building up this calculator collection. For the time being I will restrict my collection to handheld calculators from Hewlett Packard and RPN models from other brands.

This site gives an overview of my collection and a lot of general information I have collected.

This 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 buttons.

If you have an interesting addition to my collection, please feel free to contact
