Hi Stefan,
I have found your article re above ('Repairing an HP-41CX posted on 2 Apr 2000)and I wonder if you are still interested in helping with the problems in my case a ‘Memory Lost’ the LCD shows 0.0000000 but is frozen as pressing any keys there is no respons.I have lots of overlays and modulus you can have free. I have had my 41cx since 1984 and it has been my best friend so would not like to lose it.
Hope you can help,
Steven Benedict
