While fantasizing having a PDP-11 of my own, I was reading about TRIPOS
and decided that would be fun to play with. This line from the TRIPOS
wikipedia article caught my attention:
The most important TRIPOS concepts have been the non-memory-management
approach (meaning no checks are performed to stop programs from using
unallocated memory)
Does this mean that any process is allowed to scribble anywhere in memory
without provoking a segfault?
I beleive so. I'll have to look at the sources again, but I am pretty
sure that the original TRIPOS would run on a PDP11/03. And I seem to
rememebr mention of the PDP11/40 or PDP11/45 in the source, but that the
MMU was not used.
