First of all, I assume you have a 41C (not CV, not CX) and you know how to do a master clear.

One single density memory module has 64 registers, plus 63 from the calculator itself makes 127 total registers. After SIZE 063 this leaves 64 registers for programs. This is what you should see after you enter program mode: 00 REG 64.

Now, what do *you* see here? Switch to PRGM and type [GTO] [.] [.], see 00 REG nnn. What is nnn in your case? If it's 00 the memory module does not work. For a test, set SIZE 017. Do you now see 00 REG 46? Then it's definitely the memory module.

thank-you Dieter, you help me a lot

I couldn't key anything 'cause the lack of space for the programs, after sizing...

I supposed a problem with the memory modules, but I could not believe it
I discovered tonight to have at least 6 not working modules ....

May I had damaged them plugging and unplugging them for the test??

I'll test before to say it the ports of the calculators

EDIT: I tested the modules and they work just in port 1, and after a reset (of my mind, not of the calculator ) I realize that this is correct.
the OS find the upgrade of memory starting from the first port!

If I plug in all the modules step by step sizing each time 000 I can see the increasing of the add memory, 127, 191,255 and 319...
