Hi all,
I am new to the forum & have a quick question relating to my HP41CX. Does the Extended Functions Module serve any purpose on the HP41CX? I was assuming it added memory (124 registers I believe) but then I read in hpmuseum that the CX may have already included this capability. My calc certainly doesn't have this module in one of the ports. Any help would be appreciated as I was planning to purcahse one.
Cheers,
Michael
