Could do this with the MMU (wish I had one).  Trap all access to that page
of memory, and continue if it is an allowed read (like, oh I don't know, um,
maybe location 4?) but complain if it is a read from location 0.

Yeah, I know it slows things down, but it's a debugging tool.

Gee, I was wondering when you guys would notice.  (-;

I have a question that is unrelated to the subject line, but this remark
reminded me:

I've noticed that some of the ROM libraries (at least those routines I've
traced to find out what is really going on) push their parameters from the
registers onto the stack.  Considering that at least one C compiler for
the Amiga eliminates the need to have stub routines, wouldn't it be nice
if the ROM routines themselves could use the registerized parameters
directly?  Like maybe in 1.4?

Just a thought.
