I was re-reading the KT-11 docs, and got somewhat confused, and wanted
to verify my memory, that (absent Split I&D) user programs had virtual
addresses in the range 0-0xffff, and kernels the same: 0-0xffff.
Thanks, I know this has been discussed before, but I'm giving a talk
at IWP9 next week and want to make sure I'm not missing something. The
KT-11 doc left me uncertain.
You gotta love those old DEC docs, complete with SSI logic diagrams ...
