HP 41CX math and X memory problems
Hi all,

I have a 41CX with math, IR printer, Advantage and X memory modules.

The prolems are the the calculator do no find the math and X memory modules.

In cat 2, it does not show these both modules.

In cat 4, there's a DIR EMPTY message.

The math module is ok in my CV. I can not test the X memory due I don't have the X functions module.

When I press Prgm, there are 218 REG, after a reset in the calculator.

I have tried different positions, with and without others modules.

Am I missing something here or I have a defective calculator or X memory module?

Edit: I don't know if it mathers, but the CX is a halfnut one.

Any enlightenment is highly appreciated.
