No, I have three left becasue I cleaned up and refurbished the others:
one to a listmember, and two to ex-colleagues who used to use them
extensively.
The PSUs are easy to repair.
I have three Indigos (left out of six),
Dead PSUs? At the Unix-AG we had six Indigos. Only one is alive. The
other machines died the suden PSU death. At home I have two Personal Iris (a 4D30 and a loaded
4D35), A R4k
with
the simple LG1 framebuffer and a R3k Indigo without
GFX. A R4k4-150
Indy, a R4k4-200 Extreme Indogo2, a R10k-195 Impact Indigo2 (the
machine
I am sitting in front of right now) and an Octane.
(R12k-300, ESSI +
ESI
dual head, 2 GB RAM, PCI card cage with additional
SCSI and FDDI,
total
of 36 GB disk, CD-RW, DLT)
I have an Indy R4400SC-150 as well. I was always rather disappointed
with its speed, though; it's considerably slower than most of the other
Indys. I never liked the look of the Indigo^2 so I don't have any of
those. I'd like your Octane, though,if you ever get tired of it ;-)
and a
16-processor x 180MHz R10K Origin2000.
A Origin2000 is nice, but I would prefere an
Onyx2000. ;-) > > What I really want one of these days is a

He. I have an extra machine room and run extension
cables through the
wall. So I don't care about noise. :-)
Ditto for my Origin (and the PDPs etc). The machine room is an
extension to the house, and I have UTP, serial lines, thinwire, and
fibre between m/c room and office.

One of us tried to
repair them. He has experience in these things but
was not able to get them back to live.

I don't care much about the look. The R10k Impact is a bit
limited in
memory / bus bandwith and IO, but still a nice machine.

Well. I bought it (without PCI options and single head) about a year
ago
for 300,-EUR. R12k-300 (E)SI Octanes are still the "sweet spot".
:-) The O2K I helped look after in Computer Science
was a 32
processor unit and it had a graphics unit. Nothing like Onyx
graphics, but I would have liked that.
To be onest: I don't have an application
for that many CPUs. I need one
or two faster CPUs, not several slower CPUs. Nevertheles an Onyx2 would
be a nice machine for "personal workstation". ;-)

I have found that an Onyx with four R10K 195MHz processors, 2GB of host memory
and Infinite Reality Graphics with two Raster Memory cards is truly the
"Sweet Spot". Performer will run in "real time" with beautiful
anti-aliasing
and texture mapping, etc. It's truly an incredible machine. (A similarly
equipped Onyx2 would even be better ;-)
I have a 2.6GHz Intel Pentium IV "game machine" with high end Nvidia graphics
(plays "Far Cry" without any "jerkyness") - and in the many real world
video
benchmarks I've performed, the SGI IR beats the "game" machine hands down -
in performance, visualization, smoothness, etc. OpenGL in silicon really
helps :-)
It's just hard to beat the SGI's video quality and speed - especially for
multiscreen applications (my Onyx IR supports seven monitors - although I
seldom use more than three at the same time)...
Cheers,
Lyle
