Learning to input programs on HP-41

Hopefully the new cable will work, however if not, definitely reach out to Michael and let him know your 41X is defective, he will take care of you, likely sending a new PCB since that's easy for your skills.

While that would avoid a no-doubt interesting adventure chasing signals on the board, you probably do enough of that on machines where warranty repair isn't an option.
