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