Calcu-Light XP - how to separate cases?
Hi, all. My XP that I've had since the '80s has decided not to work. I tries new batteries with no success. There is no corrosion evident in the battery compartment. I want to split the case to check for internal corrosion, cold joint, etc. Does anyone know how to split the cases? I removed the two screws by the batteries but there is something else holding the case together.
I contacted Quantum Instruments but they no longer have technicians who work on the XP.
Any suggestions will be appreciated.
