You can pick up a refurbished SUN SPARC 5 180 MHz box for about $1000, or a
110 MHz for about $600. This is the faster 51B box, and the 180 MHz should
be pretty snappy. We upgraded from 51A to 51B (old 85 MHz boxes) and saw a
big improvement. I don't know exactly what else you need, but make sure you
get a TurboGX frame buffer card (I know these are Foxboro OEM and will
work). Also, load up on memory - 128 MB minimum.
I know not the legalities involved, but technically this will work.

Subject: FW: Upgrading Foxboro Boxes
This note came to me from our Decatur plant. Any suggestions?
We are looking at a problem that is going to be experienced by other
plants
in the future. We have a Foxboro I/A system here on our Cogen plant.
We have
AW51s (A series) and V6.1 software. We recently installed the OSI PI
system
onto one of our AW51s. What was already a slow box has become almost
unusable. We have received a lot of complaints from the plant
operators -
especially about the graphic call up speed.
We have talked about upgrading the boxes to the latest AW51s (series
D or E)
to speed things up. Unfortunately we are being quoted $100,000 by
Foxboro.
What makes this worse is that we know we can buy the boxes from Sun
direct
for 30% of the Foxboro price and Foxboro are charging us $50,000 for
software licenses. Foxboro are not being very helpful at this time.
When we
proposed buying the boxes from Sun, Foxboro refused to support these
boxes.
We are wondering if it is technically possible to buy the new boxes
from Sun
and try to load the existing software on ourselves. This would mean
that we
are using the same software licenses but should get a better
performance. We
have asked Foxboro about this and been told that it is not possible
because
we need to buy new licenses from Sun. We have asked Sun about this
and they
have told us that we do not need new licenses but they do not know
if this
would work.
Does anyone have any thoughts/experience in this matter. Is this
possible or
are we missing something somewhere?
