I should have mentioned that "rescue" in this context meant to use on
my desk at work instead of $garbage_x86 box bequeathed to me...so no $
will be spent on it.

Aside from the extra RAM that we collected from the U30's that went to
surplus, it is indeed in that condition.

Did some basic dusting--no canned air here (hell had to bring in my
own tools--have I mentioned I dislike working for $gov_agency?  You
know I haven't had a new machine at any workplace since 2001. Feh.)

Check.  PSU, etc. all spinning up as they should be.  It will sit at
OK for hours (days) and boot fine--but 5-10 min after booting, it
freezes.  I guess this should make me suspicious of RAM, but I'd
expect a kernel panic not a freeze.  Will trim it down to minimum RAM
and see what happens.  Again, it seems odd that it doesn't report any
errors from self-test run from PROM.  Anyone know if there's an equiv
of memtest for UltraSparc?

Tried that too after the initial issue with the jumpstart install.

Btw, good "reading between the lines" on the U60 listing & purchase.
