RE: I need help with using the 41CL
I have nearly the same issue. Where is my mistake?
I have done the initial configuration from page 18 of the HP41CL manual, steps 1+2+3. Afterwards I have typed: alpha math alpha xeq alpha plug1 alpha I have tested the math modul with command sinh. It runs. Afterwards I wanted to unplug the math modul with the command: xeq alpha uplug1 alpha. HP41CL shows : nonexistent. I was not able to unplug the virtual math modul. It is still plugged in and I can see it in catalogue 2. Does anybody knows how to unplug it? Greetings
