Sun mannagers,
        The consensus is that I just plug in the CPU+dc-dc converter and do a
boot -r. There is also an issue about which slot to put the CPU in and how
to arrange the RAM. That information should be in the documentation for the
upgrade when I get it (if anyone wants to know just say so and I will tell you
but it will probobly be at least a couple of months before my company gets
around to buying anything). I have included all of the replys that I recieved
as an attachment (in UNIX mailbox format).
