The extended memory module does not overlay the quad memory in the 41.
I prefer to think of the extended memory/extended functions module as
" file space " for the 41 (you see, it includes an extended memory
directory command - EMDIR).

With the EM/EF module, I can save a program I am working on, freeing
up the space in the main memory. I only use the card reader to archive
stuff.  The 127 registers are independent of the main 41 memory.

In fact there is also another extended memory module to expand the 127
register EM space.  The two of these combined should be more than enough
space.
