This just shows the free memory allocated for programs. Assuming you do not care about the programs or data in your calc, you can clear all memory (turn calc off and then turn it back on while pressing the <- key), and do a SIZE 100. If this works and there are no memory modules [1] attached to the calc, you have a CV. If it fails, you have a C.
If you want to preserve memory, do a CAT 1, noting the sizes reported next to each END statement and add them to the 46 you have available. This is the entire program memory. If it is > 64 you have a CV, if not, do a RCL 99 to see if memory has been assigned to registers. If this succeds, you have a 41CV.
BTW the "lateral port" just provides access to the battery compartment, and unless you have a really early model you should not see any contacts there. If you have the rechargable battery pack this port allows you to plug in the charger while the pack is inserted in the calc.
**vp
[1] memory or quad memory should not be connected to a CV anyway, but having X-memory modules is OK and does not affect this procedure.
