  If you can, get the August copy of Unix/World.  Pages 93-95 have info about
it.  Some features:
	1.  up to 6MB of memory may be used by /xenix itself
	2.  Support high res graphics, as you stated
	3.  Ability to format media in multi-user mode
	4.  Auto reboot capability
	5.  Auto screen dim on console after 20 minutes of non-use
	6.  Correct handling of the new DST
	7.  Newer and better version of mail (could it get worse?)
	8.  New version of csh.

     What?  You mean you never noticed that three way jumper on the 68000 board
   next to the 24MHz crystal? :-)  It switches between 6 - 8 - 12 MHz modes.
   Just need all of the support chips to handle the high speed (I tried it...
   it wouldn't work on mine, but then again, I have the *old* board; 8MHz
   doesn't even work [and yes, I still have those stupid memory boards that
   take 64kbit chips]).
     I've always thought that the Z80 should be faster than it is, but whoever
   is doing the speed mod for the Z80 should take it up to 8MHz, if at all 
   possible.
****  If you find out how and/or where to get the high speed mods, please
      either post it or e-mail it to me, thanks.  ****

	I have a 10MHz AT with 1 wait state that beats the PS/2-60.  I don't
    think it's that hard to be faster than the PS/2-60... but like everyone
    claims, the compiler probably made the difference.

      According to the Unix/World article, the "6000 will continue to be
   offered in the 1988 computer catalog."  Your guess is as good as mine.

	a) What about 64k DRAM cards to 1MB DRAM? :-)
