Ditto here, but we're the exceptions. Luckily, the FE who handles us
is an old, old friend and has been with Sun since the early days.
Between us we've cobbed up some amazingly fun fixes.
Helll, I remember having to solder cross-connections on Sky FFP
boards for Sun2's. :-)

Yep. And, in all my years, I've bent exactly one pin. If you're
careful, you should not have breakage.

I'm of two minds on that one - having seen the design side, sometimes
the connectors are needing that, especially the BGA stuff on big
custom ASICs. However, the geek in me prefers being able to fix
anything with a screwdriver and duct tape. I compromise by not
trusting any computer. :-)

Yeah, but by the same measure, multi-million-dollar SMP boxes should
be in a decently clean and environmentally controlled data center.
I'm sure you're not surprised when I say I've seen some real
horrorshows. (And, for $DEITY's sake, don't put a water line through
the ceiling of the data center, especially if you live in
geographically unstable areas....)

Oh, in this case they knew, but they didn't see the reason why
shutting down was so bad. That's why our group got involved.... :-)

I suspect the only problem I'll have with it is the NVRAM.
Otherwise, like the 2/120's I finally divorced myself of, it would
make it that long. (My 2/120s were still running at almost 25....)
I won't argue, I miss real hardware. But, you also won't see me
giving up my MacBook any time soon. I liken it to enjoying nature
and a pristine view, but also really enjoying flush toilets. :-)
