umm, i am a little bit confused by this...  you are saying that the
most memory you can put in an Amdahl is 512M main, but that a "good
percentage" of mainframes are shipped with more than 1G of main
memory?

what is the difference between "main" memory and "expanded" memory?
if "expanded" memory is just a back store for paging and disk cache,
then i dont think that including "expanded" memory is what people
normally think of as "physical memory".  (you can also exclude ram
disks and the memory on high res video cards)
