The 'Memory Peeker' CDA is built-in on all ROM versions of the
Apple IIgs, you just have to invoke it. There are two common ways of doing
this. Enter Monitor with the command "CALL-151" and at the '*' prompt enter
a '#' sign followed by return and a warm-boot (CTRL-OA-RESET). Or, if you
have System 6.0.1, use the SetStart CDev and select the Invoke Programmer
CDAs checkbox. Both 'Memory Peeker' and 'Visit Monitor' will appear until
you power down the machine. The ROM 00 uses a different Monitor command to
invoke the CDAs, though I don't remember what it is off hand.
...Of course if you have a certain model of the ROM 3 (like myself)
you'll be plagued with those CDAs in your menu forever! :/
