From time to time we receive emails on whether we repair HP calculators. This makes me wonder on how well we communicate: this is what we do! So we have thought it out and decided that apparently it is not clear from our website. Then we have decided to open a new department on the website about repair.
We are specialists on HP41 and card reader repairs, but we also have a partner (Ignacio Sánchez) who is expert on the rest of calculator types: Woodstocks, Classics and Spices.
We think that newer calculators (Pioneers, Clamshells and the HP48 family are far more difficult to repair than the previous models, much more modular and where the problems are typically mechanical in nature. And for some models (HP50g, HP17bII, you are much better off if you just buy a replacement off an auction site.
We also sell parts for repair (now based on the HP41 family but also battery solutions for other ranges too) and we plan to offer calculator enhancements (HP41CL in the past, bu we will try the Panamatic and Teenix solutions that improve on the previous calculators with a number of interesting additional features.
