Thanks for the info -- this is helpful for me also. However, it does raise
an important question for me.

If I order extra SGI memory now for my existing PIs (to go from 8 to 16Mb)
with the intention to upgrade the machines to 35s later. Am I going to
have to throw that memory? I am talking about 18 PIs so that is a lot of
money/memory.

I guess the question really is what is the upgrade policy on 4D20/25 to 4D35
