Amongst other things, I picked up a SGI Indigo2 system yesterday. It turned
out that it had the original packaging, and that it's an Impact 10000 machine.
For graphics however it has a four-board set; does anyone know what this
might be? Wikipedia talks about a three-board set for the Maximum Impact,
and fewer cards for lesser options, but I've not seen mention anywhere of a
machine using four (unless they're just not counting the analog output
board as part of the three?)
I'm not sure what it has for RAM; all of the sockets are filled. Someone
had scribbled 32MB and 1GB of disk on the box, but it has 2 x 4GB drives
fitted, so that's not necessarily correct.
I need to clean the dust out before I try powering up, but does anyone know
what a minimum config would be? Can I power up with no disks and
framebuffer, and expect to get a serial console? I'd like to not stress the
PSU (or risk the framebuffer cards) initially if possible - the previous
owner said they never ran it, although it was supposedly working when they
got it.

Just on the back of that, the board with the 13w3 is actually the second
board down. The top board has a DA26F connector and a connector with three
rows of 15 pins each. Not a lot of clues on the board as to its purpose,
although it does say MGV1 in one corner. Maybe some form of hardware MPEG
encoder or capture board?

You should be able to power the machine up without drives or graphics
options. If no keyboard is detected, all console IO is directed to the
first serial port.

... and, we're up and running. No immediate problems, apart from a broken
connector on the sled for the CDROM drive, which is really a non-issue
right now as there's no CDROM drive in the machine anyway (and the disks
have a viable OS).
The High Impact board set has the optional 4MB of texture RAM, so I'll be
looking for a copy of Quake 2 to run on it :-) It's got 384MB of RAM, which
is likely a healthy amount; I think 512MB was the official max on these
(and it sounds like they'd take a bit more with 128MB modules), but it
already gets pretty toasty in there with the graphics options that it has.
Oh, it turns out that it's an ex-Cray system. It looks like it's still got
Cray-related data on there, but whether it's anything
useful/interesting/non-sensitive etc. remains to be seen.

I work in medium-scale HPC (~3-4K cores, ~8 petabytes online) and we do run
NFS in async mode still to this day for performance's sake (of course,
cognizant of the potential risk involved). Honestly, on Linux, our
experience has not been bad. If we're talking about things SGI did that can
be dicey, I would focus more on XFS :O
I don't mean that as a burn to anyone involved; Dave Chinner and team does
a good job with the resources they have and the Linux kernel they have to
deal with and XFS does fly even if it is a little fragile sometimes...
Always had good luck with it on IRIX at home... but my duty cycle at home
is much, much, much lower than at work, LOL.
I would love to get my hands on an EISA multimode OC-3... I have a ton of
Fore PCA-200 cards stashed and I am still running OC-3 ATM in production at
my home on a ForeRunner LE155 switch and it would be great fun to tie in
one of my Indigo2s.
Anyway, more on-topic, congratulations, Jules, that's a fine system you
have found! My strongest Indigo2 is a bit of a Frankenstein :O Non-factory
config... R10K at 175 Extreme in green skins, non-Impact PSU, 256 MB RAM and
it runs IRIX 6.5.x very well; graphics performance would be horrible for
anything textured but for regular interactive use, browsing the Web,
running all the demos, it's plenty fast. I have a few more in my storage
room; one of the more rare R8K systems, an R4K/250 system (which is also
pretty quick) and another R4K system and a half in parts... I was obsessed
with these things when I was in high school :O
IMO, Indigo2 systems are great machines; I have found them to be very
robust in the long-term although from my experience the Impact PSUs seem a
bit more prone to failure than the non-Impact PSUs (the mode seems to be
harmless to the rest of the system; it just one day decides it won't power
on; reminiscent of how I've seen the Nidec supplies go on the Indys). Parts
are pretty easy to find and fairly inexpensive as SGI equipment goes.
If you want to know the specifics, you have probably found this already,
but there are two SGI-specific commands you can run from IRIX, "hinv" and
"gfxinfo" which will tell you what's there.. You can also run
"hinv" from
the ROM monitor.
Have fun!

Sean

out in the wild.

I'm certainly wary of loading this one up with more RAM just because the

Oh, this machine has the optional feet for standing it sideways, too - I'm

Yup. I *used* to know my way around them. I'm just very, very rusty right
now :-)
I got an Origin 2200 at the same time which I'm just working on cleaning up
at the moment. I've got four node boards for that one (2 CPUs per board)
and an enormous quantity of RAM, but as of right now I'm not sure if the
boards all have compatible CPU types (I think some mixing and matching was
possible, but not all combinations work), and I have a feeling I may need
an additional board (which I don't have) anyway to build an 8-CPU system.
Still, 4 should be possible (and as a plus I can run that from a regular
outlet).

Sorry, it's a teal cabinet; I'm crass; I call them "green" and
"purple",
respectively, for non-Impact and Impact I2s :)
You are right, even the interactive performance of the R8K had me a bit
taken aback; it feels more like you are on an R4K/100 or R4K/150 machine at
best. But I understand in its day it really flew on the FP codes; the claim
was something like the R8K could sustain the FP performance of a Cray Y-MP
EL CPU or something like that... I don't know if this claim was ever really
substantiated in the real world... But it's a neat little oddball; I like
having a white elephant around.
I guess I was just lucky to get into the hobby at the right time ca.
1999-2001 when a lot of this particular gear just happened to be hitting
the secondhand market... I got a lot of my gear from a great guy, Herb
Johnson, maybe a few other folks here have done business with him... he's
out on the east coast somewhere... and I think he got a lot of his stuff
from academic property dispo sales. I've gotten a
few directly from
property disposition at various Michigan universities; a friend
also got
one via the same means. Very little of what I've got came out of a private
commercial setting (although I have mostly /worked/ in academia).
Great that you got a pair of matching feet! Use em! I think the system
looks absolutely gorgeous when on stands. Laying an I2 horizontally on a
desktop does not do it justice, IMO ;) With all my SGI scrounging I only
ever ended up with one pair of stands and I keep them on my display
system... I don't know that it affects cooling efficiency much how you've
got it oriented so long as there isn't stuff piled up around the bottom
blocking airflow when the system is vertical.
Good luck with the Origin, I've never personally owned any SGI that
large... closest I come is I've got some guts to a Crimson. IIRC that
hardware was considered kind of "finicky" in its day so might not hurt to
run in a reduced config and keep some for spare parts.
Best,
Sean

True. And it's not like I *need* all the boards fitted anyway. It just
would have been nice to fire it up as an 8-CPU system just once :-) (the
one I had at work back in the day was an 8-CPU machine; I remember Oracle
throwing a fit one day, because they licensed per-CPU and had been under
the impression for months that it was a single-CPU system)
It looks like I've got 3GB of RAM for it - all in 64MB modules. There are a
lot of them...

Yep, Control Data rebadged several SGI machines; I've seen (pictures of)
Indys with CDC stickers on them, and I personally have at least one or two
Indigo machines rebadged as "Control Data Cyber 910" as you say; the color
is the same as the stock Indigo but the silk-screen on the front, and the
manufacturer label on the rear, instead says "Control Data".
My entire stock of Indigo (and older) SGI serial keyboards is branded
Control Data as well!
They may also have done this rebadging to some PI/Power Series machines and
Indigo2s... I think sgistuff.info has some photos of a CDC-rebaged Personal
Iris.
We probably don't get the Siemens ones over here in the US; as far as I
know... Anyone stateside got one?

Nice!

amount;
For retrocomputing tourism, that's plenty. IRIX has a typical 1990s RISC
memory footprint, outside of memory hungry modeling/effects/video
editing applications.
I think 512MB was the official max on these (and it
sounds like they'd
take a bit more with 128MB modules)
An Indigo2 with the older R4k CPU modules (IP22) will max out at 384MB,
using 32MB fast page mode parity SIMMs. The R8k CPU systems (IP26) will
max out at 640MB using 64MB SIMMs, and officially the R10k CPU modules
(IP28) will get up to 768MB using the same 64MB SIMMs.
But yes, using 128MB SIMMs you can get to a full gigabyte, as documented
here by Ian Mapleson: http://www.futuretech.blinkenlights.nl/i2gigaram.html.
General information about the I2 can be found here, including pointers
for 128MB parts that should work in a 1GB configuration:
