I belive they are pinless, how does that work then!
I learned that Sun hardware is much heavyier but still much more
vulnerable to mechanical misstreatment then any PC hardware. So i
wouldn't do it. Don't you have a 900 Module ?
As usual, complete baloney. My Sun Blade 2000 came from Japan, and when
I went to collect it the box was dropped over about 1m off a shelf. It
booted without a problem. A HP business PC purchased from a local
dealer had a loose CPU fan and video card when I took it out of its
box.
You have some anecdotic experiences with a couple of systems you bought
from the cheapest possible secondary sources. Hardly a reason to
generalise - and you've been told so many times.
And remember that the 900 USIII-Cu module will not work only the older
900 USIII.
The 900Cu processor will work well in the Blade1000 - just that you
cannot mix them with non-Cu processors, or mix speeds (like you could
with the non-Cu versions of the UltraSPARC III). I believe that some
very early revisions of the Blade 1000 motherboard can have issues with
the Cu processors, but that's about it.
Sun Hardware is almost impossible to upgrade as we all learned
here :-(
Please don't use the word "all". I've successfully upgraded many Sun
systems, and my experience is that they remain usable far longer than
comparable PC equipment.
Some systems (like the IPC and IPX of yonder years) were designed to be
as small as possible, and hence were difficult to upgrade.
The PCI based systems are quite upgradable, hardware-wise. Certainly
no less so than cheap x86 based kit. For example, I cannot seem to find
a Slot 1 CPU that will upgrade my 900MHz PIII system; the same system
cannot take more than 384MB RAM (courtesy of no BIOS upgrade, and maybe
even lacking traces on the motherboard). Intel and AMD for sure aren't
going out of their respective ways to allow easy processor upgrades
(care to enumerate all the different processor slots?), and the typical
PC has not much scope for memory upgrades (how many 1999 vintage PCs do
you know that take up to 4GB ECC RAM?).
Please go and peddle your prejudices somewhere else.
