Ok, ok.  I see that my hint wasn't blunt enough...

There is no such thing as an address that does not exist on the IIgs.  The IIgs
has no memory protection scheme, no virtual addressing, nothing.  Any 24 bit
address given to the machine to access will end up reading or writing
SOMETHING.  I emphasize that, because the something could very well be an open
connection to the atmosphere (ie: not mapped to anything, data lines just
floating), but the processor will still attempt to read/write it.
