  I quite agree that without a MMU, Unix just isn't realistic - but what
bugs me about all the '20 and '30 boards is that I can't `detach' them
from the Zorro II bus and let the 68000 do I/O, interupt processing, maybe
even the low level buffer caches... AND run an X server! (As an AmigaDOS
task of course...)

  One of the CA guys said something to effect that they wished that all
this work on Unix would go into 1.4: It seems to me that AmigaDOS
with an MMU just isn't realistic (and Unix without isn't)
   It would be nice if AmigaDOS moved closer and closer to Unix, with
vnodes or GFS (Generic File System - a la DEC) and real processes. Keep
most of Exec and Intuition but junk AmigaDOS itself.  Also - as long as we
are doing this, don't make it '020 or Motorola specific, (beyond msb first)
and replace Janus too... Who'd want to run MS-DOS on your '386 board
anyway?
   I WANT the features of Unix. I would like to keep a faster interrupt
sensitive OS.
