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...) > > 2.

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. David W. Berry A/UX Toolbox Engineer dwb@apple.com
