Sorry Patrick.  The problem with trying to state numbers is that
if you get it wrong, then the real knowledgeable ones can point it out.

I figure out list cost on a 256 node system at about $2000 before for
basic hardware.  I as wrong.  I reworked it and it is $1500 for
256 (and would be the same for 512 and 1024).

I thought I had decent information.  What I was trying to provide was
info on the three options.  The SCI price is per node (cards, cables,
software).  It is $2245 list.  This would be appropriate for systems over
144 nodes.

The Quadrics number I got from the rep might have been the sales number,
and not a perfect comparsion to all the required hardware for a system of
a few hundred nodes.
