[rescue] Ultra1 and SS20 NVRAM

[Eric Dittman]

I took my Ultra1 completely apart and put it back together,
hoping there was something loose causing my problems.  No
change.  However, when I pulled the NVRAM I got the following:

   TPC=ffff.ffff.f000.016c TnPC=ffff.ffff.f000.0170 TSTATE=0000.0000.5800.0400


Which is a lot more information than before (with the NVRAM
I got nothing but the RED State Exception over and over),
and the RED State Exception codes are different and don't
continuously repeat.

I took the NVRAM out of my SS20 and tried it, but I get
the same RED State Exception as with the Ultra1 NVRAM
installed.  Are the NVRAMs compatible?
