Need Help With HP 41C Calculator Repair
Does anyone know where I might be able to get an old HP 41C Calculator repaired or where I might find information on repairing it myself. Hewlett Packard quit making these probably 20 or so years ago. I have had this one since somewhere around 1980 and it has worked until about 6 or 7 years ago. Since it quit working I have not been able to locate anyone that repairs them. Any help would be very much appreciated.
