Hi,
I found my old HP41C in some drawer, and I've been amazed
by the quantity of documents and stuff on the web ! I want
it to be my calculator again.
I remember a very old french magazine having an article
on "How to upgrade 41C to 41CX by doing some electronics
inside the calculator, i.e. adding MEM and X modules BUT
leaving the four external ports free).
Has anyone some experience on doing this ? I remember that
41C was pretty low in memory, and I'd like to keep external
ports free for peripherals.
By the way, what is this "Advantage" pack ?
Thanks for any help
Stephane
