OK, so let's really do it right:

	comp.unix.segmented.swapped.byte-backwards	(i.e. 286)
	comp.unix.segmented.paged.byte-backwards	(i.e. 386)
	comp.unix.linear.paged.byte-backwards		(i.e. VAX)
	comp.unix.bank-selected.swapped.byte-backwards	(i.e. PDP)
	comp.unix.linear.swapped.sensible-addresses	(i.e. 68K)
	comp.unix.linear.paged.sensible-addresses	(i.e. 68020, 030)
	comp.os.minix.wimps				(for PCs and clones)
	comp.os.minix.real				(for STs and such)

The 286 and 386 are very different processors, and the OSs for them are
very different, too.  comp.unix.microport was formed for Microport
users, leave it alone.  Xenix is a half-breed bastard, let their users
have their own little corner.  So we have:

	comp.unix.i286		Unix systems on the 286 processor
	comp.unix.i386		Unix systems on the 386 processor
	comp.unix.microport	For Microport owners/users
	comp.unix.xenix		For SCO/Microsoft/etc. owners/users
