The Museum of HP Calculators
The Museum of HP Calculators displays and describes older Hewlett-Packard calculators. There are also sections on calculating machines and slide rules as well as sections for buying and selling HP calculators, an HP timeline, collecting information and a software library.

Really good little demo of doing physics on a plotting calculator. But the best part is at the end:
If you amortize it for 5 years, and divide by all the student workload, you get the remarkable cost of 5¢/program (40¢ in 2024 USD)! What a bargain!
By my calculations… that's $7,020 ($56,843 in 2024 USD).

Dave@hasheddan have you looked at at any of the #hpcalculator processors as part of Microarch ? There’s a least one custom processor they built, the Saturn. @brouhaha knows a bunch more that I do.
Jun Nergahak 🌺🌺🌺A real screenshot by my smartphone. I installed Emu48 and turned it into a powerful graphing calculator, its my HP 50g.
I configured it to be full screen and hiding device information, making it behave exclusively like a real HP50g.
Wolfgang StiefQuite a while before HP came out with their iconic, RPN based pocket calculators, they built a successful line of scientific desktop calculators. Those pocket calculators were invented by Tom Osborne, then not yet an employee of HP. In this interview, Mr. Osborne tells the story on how he came to the calculater, how the calculator came to HP and what happened at HP with desktop calculators.
