- So why hasn't memory protection and resource tracking been implemented on the
- Amiga? It doesn't SEEM too difficult of a project; use the MMU to make sure
- that a program only acceses its own memory and public memory. If it tries to
- peek where it's not supposed to, terminate that process and free up its
- resources. This of course would require Amigas with MMUs, so it couldn't be
- used on the low end machines, but then the people who use the low end machines
- are typically not the ones who would require memory protection.
-
- I must say that I have never programmed an MMU, and I don't know how difficult
- of a challenge this would be. I would love to hear other peoples' comments
- and ideas on this subject.
