My catalog 4 (extended memory) on the CV has a lot of commands. i.e. *,/,+, -, ACOS, ADV, ASHF, ASN, etc. I did not put these there so not sure where they come from. They may be used in the program somehow to keep main memory usable. Both calculators did hold the program at some point.

No. Unless you put an XMEM module in the CV, it comes without any extended memory. What you see from CAT 4 is simply the output from CAT 3 (you may try with CAT 5, 6, etc. it is always the same) that is the list of 41's internal functions.

That said I can't help you in determining where your problem lies, sorry.

Can I put a quad memory module in my CV and get extended memory or is it to only boost the 41C to a CV?
