I've come into possession of an HP 41-CX calculator - unfortunately it appears to have had batteries left in it which have left corrosion on the internal contacts.
(some pics: https://photos.app.goo.gl/48bE7WJZP8R4PF9a9 ) My classic hardware tendencies tend to run more towards the "can run *nix" end, and while I could just clean it up and throw it on eBay I wondered if anyone here has a 41C shaped soft spot and would be interested? (happy to trade/part trade for something they already have for which they are less fond if that works :) David
