I talked with David {can't remember} at Honeywell late last year, and
he said that Multics "could probably" be ported to the 386, and guessed
four man-yr to do it. I suspect that this will never be done, and it's a
shame. Most of Multics would run nicely with four rings instead of
eight, except (I believe) the debugger)?
