On a hunch I took the RAM and NVRAM from my Ultra 2 and put it
in the Ultra 1.  It seems the Ultra 1 NVRAM was part of the
problem as I actually get more information that points to the
failure on the Ultra 1:

====================
I don't think this is something I can repair, though.  The
printed legends on the board are not the easiest to see,
but U201 looks like a large PGA.
