Extended Memory on the 41CX
In trying to determine how much extended memory my 41CX has, I did an online search and found an answer here:

What has me confused is Richard Garner's reply to Jon's post, because the results I get on my 41CX don't seem to agree completely with his reply. I have an X MEMORY module installed on my calculator. This is what I did to determine how much memory it had:
First, I removed the X MEMORY module. I then entered 0 four times to load zeros in the x, y, z, and t registers. Then I did shift+catalog+4, and the display said DIR EMPTY. I then hit the correction function key and 124 showed up in the display. I repeated this procedure after re-installing the X MEMORY module, and got 600 in the display. I was expecting fewer registers, because Richard Garner's reply indicated that 2 extended memory modules would be needed to get the 600. I have only one X MEMORY module installed. What am I misinterpreting? Or is Richard Garner incorrect?
