Dead 41C?

[Jean-Michel]

Thank you all three for your prompt and detailed replies!

I will print them and plan some free time to cure my old lady. I tried to firmly press the shells one onto the other this morning, with no success, but I did it only once and probably not firmly enough and also not at the right place, so I will try again better. I was at work with not much free time, so I picked up my 33C to do my computations and leaved the problem aside.

I will keep you informed of further steps and come back to you if needed.
Geoff, don't be afraid, I won't throw it out, even if my skills are not good enough to make it work again! These are venerable pieces of calculators.
Cheers.

JM.
