This would be so only in AppleWorks 3.0 and higher. AppleWorks 2 would have to
have expander software added to recognize the extra memory at all.

In AppleWorks 3.0 and higher, peek $0FE0 will tell you not only if there is a
memory card, but what type it is. If Peek $0fe0=0, no memory card. If Peek
$0fe0=65=Bank-switched (AUX) memory card like Z-Ram. 88=Slinky memory card like
Apple or Sequential.  82=Apple IIGS. To read the peek in AppleWorks, you need
to either have UltraMacros, or dump yourself into the monitor (or visit monitor
in the IIGS) to read it.

I am sure there is an easier way, but that's how you do it in AppleWorks.
