	Just to clarify.  The Macintosh OS, running in 24-bit mode (the normal
	state on the Mac today, can only use 8 meg of physical memory.  There
	are a few hacks (Virtual and the 7.0 virtual memory) which will allow
	you to access up to 14-# of slots filled, meg of virtual memory, but
	you are still limited to 8 meg of physical memory.  There is currently
	only one way to take advantage of more than 8 meg of physical memory
	and that is to run A/UX.  If you run MultiFinder under A/UX, you are
	currently allowed to create a Macintosh partition with up to 16 meg
	of virtual memory (sitting on top of however much physical memory
	you put in the machine, even more than 8 meg...)

	Much of this is from memory, but I believe that current versions of
	Microsoft products, PageMaker and OmniPage all run under A/UX.
	OmniPage can't access scanners, though, so it is of limited value.
	I know that Microsoft Word 4.0 and Excel 2.2 both run just fine
	under A/UX, as I run them on a daily basis.
