HP-41 application module for basic electronics?

[Sylvain Cote]

In the HP-41 Circuit Analysis Pac Manual you will find the description of two programs that may do what you are searching for ...
GNAP → General Network Analysis Program
LNAP → Ladder Network Analysis Program

edit: oups it seems that brain skip over the part that said "I have the Circuits 1 module in my HP-41CX and can initialize this by following the manual but this does not seem to do what I recall.", sorry.
