Hewlett-Packard calculators

Hewlett-Packard is without a doubt the most collected calculator manufacturer in the world. Looking at the quality of their calculators, this is not surprising. And the fact that they can claim many firsts also helps. The first pocket scientific calculator (HP-35), the first programmable calculator (HP-65), the first alphanumeric calculator (HP-41).

The list of Hewlett-Packard calculators is sorted chronological from oldest to newest.
