Hi;
do you have an extension for the HP41 ports? I'm a lot curious and I would like to know how does it look like.
Mine are conventional, 4-places ports.
About CON and any other HP41 function: the goal is not to protect the code itself, even if it is a consequence of the use of M-code (machine code). By using M-code, many internal resources are easily and directly accessible, being in some cases, unavailable for programs.
It's a fact that CON could be written as a program, but for sure it's functionality would be sacrificed somehow, and it would probably use resources that would be needed by other programs, like subroutine calls. Also, an equivalent program would be bigger than the function.
Cheers.
