I JUST managed to get a DN420 node working.  We had a DN420 with a faulty
power supply, and recently aquired one with a bad hard disk.  I took pieces
from here and there, and got one working node.

The question is, is it possible to use memory from the non-working node
as extra memory for the one that works?  Each of them have two memory
boards in slots 1 and 2, but slot 3 is empty.  Would it work if I took
a memory board and put it in slot 3?  Do any jumpers/switches need to be
set anywhere?

Also, with two displays, and two display-boards, would it be possible to
run two displays on one machine?  If so, what would this entail?

Thanks.
