Maybe we can get of the Amiga vs ST bit and switch over to
"Does UNIX really need MMU: discussion.
I couldn't help but notice that there have been multiple
postings from Dublin, Ireland about how the ST has no mmu, never will
and therefore can't run UNIX. Memory manegement is a luxury,
not a necessity. I've seen UNIX evolve since its early days,
when you could sit down and pretty much see what's where in one
weekend if you had the sources. Unix has since changed, but neither
then, nor now do I see why MMU is necessary to running
unix. I do, of course, assume that the environment is fiendly,
and security is not an issue, moreover that programs don't randomly
walk all over memory. (this latter may a very strong constraint, seeing some
code that is floating around).
So my version of the bard's song is:
THE ST HAS NO MMU
SO WHAT?
IT THEREFORE MAY OR MAY NOT RUN UNIX ....:-)
(If you had seen earlier postings, it would help)
