< Yes it does have VM, but like most other Unixes, even if it didn't have < VM (ie it swapped), it would still an MMU to do process address space < switching and to protect processes and the kernel from each other. Since when do processes need protection from the kernel? Is A/UX that unstable or something? And how does the MMU accomplish this, since the kernel can reprogram the MMU? A kernel that is out to get a process ain't gonna be stopped by an MMU! :-) Tim Smith
