I have fond memories of using this calculator growing up. It’s been stolen on several occasions from my father during moves and he’s replaced it just as many times.
When he passed, it was one of his things that I wanted, but it also mysteriously disappeared.
I purchased my own today and am happy. It’s not the calculator my father used, but it’s still a first gen 12C and it brings me joy.

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.

In 2025, someone thought it was a good idea to release a "new" RPN calculator, because apparently calculators that look like they time-traveled from the 1980s are THE FUTURE! 🕰️🔢 Meanwhile, the rest of us are busy wondering who needs this "powerful" paperweight when we have computers in our pockets. 📱💁♂️
