#hpcalculator — Public Fediverse posts

Found an HP 48GX #calculator in a drawer at work loaded with corroded batteries. Took it home and started cleaning it up, popped in fresh batteries and it's working 100%

The ON key is flakey but everything else works, and after browsing some forum posts the ON key works if you apply slight pressure where the zebra strip connects the keyboard to the PCB

I'm adopting it. It's mine now.

YAY! Successfully upgraded my > 10 years old HP-12C's firmware to the new 2025 version which now allows to dump and restore the calculator’s memory via cable to/from my Mac. 😊 #calculator #hpcalculator #hp12c #firmware #hewlettpackard – To see your HP-12C’s firmware version: When the calc is off hold g & ENTER and press ON. Then press 2 to see the checksum, press any key to see the date, again any key to see a copyright notice, again a key to return to the 1.L 2.C 3.H menu. Press ON to exit. 😉

Pssst … It's solving a #Sudoku! 😎 Here's the code, for the curious: https://hp-15c-simulator.de/programs/Sudoku%20Solver.htm #hp15c #hpcalculator #programmablecalculator #retrocomputing #moravia #hp #hewlettpackard #calculator #calculators #pocketcalculator

Now that's a lovely blast from the past!

Any HP calculator fans out there?

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.

Quite 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.

@SarahKL REALLY VERY cool, Sarah! Love your emulator a LOT! 💜 I own several old HP calcs, the 35, 45, 55, 67 are amongst them. Being able to „watch them work“ is nerdy awesome!! 🤓😎🤩👍👍 #hp #hpcalculator #hpcalculators #hp35 #hp45 #hp80
