The Museum of HP Calculators: Perhaps the be-all and end-all spot for Hewlett Packard calculators. This site goes gonzo on HP calculators:
- See the very first HP calculator produced in 1968
- Marvel at the the legendary HP-12C business calculator which entered production in 1981 and can still be purchased new at about every office supply store (finance geeks swear by it)
- View a timeline of HP calculators
- Thrill to various calculator simulators
- Learn RPN, the bizarre method of entering data that HP came to love
Who needs a calculator anyway? Just go running. It’ll come to you.
