Interesting Article on the Curta - John Keith - 12-13-2021 01:26 PM Saw this last night, thought it might be of interest. https://arstechnica.com/science/2021/12/the-remarkable-history-of-the-hand-cranked-curta-mechanical-calculator/ RE: Interesting Article on the Curta - smp - 12-13-2021 02:25 PM I saw it, too, and I also thought it was great. Thanks for posting this. smp RE: Interesting Article on the Curta - Maximilian Hohmann - 12-13-2021 03:11 PM Hello! When Scientific American published the article "The Curious History of the First Pocket Calculator" in 2004, prices for Curtas doubled overnight. I wonder what this new article will do to the prices... but I am pretty sure that I will never be able to ever afford the Curta II that I am still missing in my collection. Regards Max RE: Interesting Article on the Curta - Ren - 12-14-2021 07:32 PM Thanks for sharing your find! I also learned, that IF I ever get my hands on a Curta, to NOT TAKE IT APART!

Excellent advice :-) What apparently caught a lot of owners out was the hand-fitting of seemingly identical components. Correct reassembly required keeping the fitted parts together with their mates. The good news is that they're pretty robust and don't typically *need* disassembly. My Curta 2 was a refugee from a coal mining operation and didn't work when I got it. The "repair" was just removing the outer housing, flushing it with solvent to remove a couple of decades of coal dust then applying a little oil and it was back in service.
