Comp. Sci. Lines: 17 > Okay, I give up. How in the world do you do a fork() without some >sort of MMU. Let me review how I think fork() works just in case I'm wrong. Am I missing something or is it just that no one on this list ever heard of mini-unix which certainly ran on PDP-11/10s and other PDP-11s w/o MMUs. Is that sufficient for an existence proof? We ran it around 10 years ago when I was at Harvard and it did the job fine, thank you. What about the old PIXEL 68K based UNIX systems with no MMU, no memory protection etc. Hey, it ain't ideal, but it is doable which is what a comment like the above seems to doubt.
