RE: HP-41CX w/ XF-Module - just curious
Sylvain's reply had a lot of really good information that went even beyond Jürgen's original question.
I'm still a little fuzzy on the answer to the narrow scope of his original question, though.

Just to be sure I understand, please allow me to rephrase it, as I understood it.

I think Jürgen was stating this:
•The CX with no plug-in modules added has 124 Extended Memory registers.
•There is an Extended Functions / Memory Module that is intended for the C and CV, not the CX.
•This module supplies Extended functions + 124 Ext. Mem registers when added to the C & CV for which it is intended.
•While a "naked" CX wouldn't need a second copy of the Extended functions, it *could* use more Extended Memory (it can hold 600 registers and only 124 are provided fromt he factory).

Which brings us to to the narrow question:
→So... Would the Extended Functions / Memory Module plugged into a CX add any Extended Memory? Would the user now have 248 (=2×124) extended registers?
