@mogensb Argh! Thanks for the reminder. My Duracell batteries in my #HP41 were replaced just a couple of years ago. They still work, but LEAKING 😡. Not cool @Duracell The prior set of batteries lasted well over a decade, didn't leak, and only replaced when they finally lost charge.

This HP-41C had lost its module port covers and the charger port cover. Here pictures of the calculator with the 3D printed replacement parts 👏. They fit rather nicely 👌. (the battery compartment is another story though 🤔... and still needs some manual work). #hp41 #hp41c

Look at this fine board of the HP-41C: HP ICs dated 79, gold traces. Notice the three pairs of initials (maybe of whoever checked/repaired it in the past?) #hp41

It is working! 🌶 I've managed to clean and change the gooey wheel on this HP-41C card reader and now it's working again ! 😍 😍 Here I store a program called ABC onto a blank card. After deleting the prog, I load it again into the HP41. #RPN #vintagecalculator #HP41 #HP41C

I've programmed Heron of Alexandria's algorithm for taking the Square Root on the HP41 (emulator) and it works! 😂 #hpcalculators #RPN #hp41

Got my brand new #DM41X pocket calculator yesterday. A perfect emulation of my #HP41, I have purchased 40 years ago, with all the plug in-ROMs created in the last 40 years. Hightec from the past recreated and combined with Hightec from today.

#HP41 calculators are stuff of engineering legends. Here is an advert for the HP41C and its new version, the HP41CV. https://t.co/HB6SiIPmFd #retroelectronics #hpcalculators #calculators @HP
