RE: One of my 41's doesn't like its card reader
That might be. The card reader works fine on an other HP41 though, so the error is to find in the 41C. Maybe the ISA driver of the 41 is broken...

Also, shouldnt that be a problem only AFTER switching the device on? The Sound immediately comes up when i plug the reader in, not when i switch on the calculator.
