Big thick things? They're probably OK.
It's a pain to make proper AUI cables, but if they're short, you can use
lower-quality cable. It's multiple coax inside. You should be able to
find the pinout easily enough on the 'net, eg

Should be OK, but make sure the AUI connector is actually enabled. Most
cards have several jumpers to select between AUI and whatever else is
there.

It is indeed. As is the FP11-A board for the pdp11/34, and the FPF11
board for the pdp11/23 and pdp11/24.
Am2901 chips kick ass. I really like them.
Back in 1987 or so I worked at Princeton University on the
Navier-Stokes Supercomputer Project. The microsequencer for the
vector ALU in that machine is an Am2910. That was LOTS of fun.

Hi all
I recently started to find some SGi boxes up here.
Some old (Personnal Iris 4D/20, Indigos) some not too old (Origin 200!)
These could be considered a bit rarer up here in Canada.
All with blank HDs of course...
But now I run into the problem of finding an OS for these....since Irix is expensive and/or hard to find...
Ports of NetbsdMips or Linux for Mips seem incomplete, very experimental and only support a few boxes...
I wonder if that what a wise decision of SGI to keep even old obsolete versions of Irix "closely guarded" like they have...
I compare with Sun Solaris and the Sun decision to make it free...doesnt that make so much sense?...when we see SGI and Sun are struggling in a PC/Windows dominated market?
I also think about SGIs decision of using all the proprietary simms and dimms in almost all of their machines, how wise was that?
Anyone that can help me with my hunt for a cheap and recent to semi-recent version of Irix, please contact me.
Thanks
Claude
I have a problem - am I the one at fault?
I am upgrading to a "newer" system and one of my concerns is adequate
backup. Normally, I do a full backup about once a day - or once every
other day. It has been suggested that the "newer" have a "RAID 1"
controller which would use two 40 GByte EIDE drives. A "RAID 1"
system uses two disk drives and keeps two copies of ALL files
at all times. This provides a duplicate set of images - so that
even if there are only intermittent errors with one drive, I would be
aware of the problems before both drives became bad and (normally)
have time to make a complete backup before I replace the bad drive.
However, I am experiencing two difficulties:
(a) The firmware/software for the "RAID 1" controller seems to
NOT have anything that will alert the user to be able to identify
which disk drive might be bad even after a drive failure, let alone
intermittent errors.
(b) Even though my current files are (seemingly) all correct and
I have two duplicate copies, when I said that I was was going to
restore from my initial back-up from CD (I currently have no
data files, just the installed software), I was looked at as if
I was a bit crazy - why would I do a recovery if there is nothing
wrong? Even though I attempted to explain that a full back-up
includes the total recovery from scratch - at least a few times
at the beginning to establish that the procedure works, that attitude
is considered overcautious to say the least - at the worst it is:
"So what if you loose all you files, you can always rebuild the
system from scratch if you have to?" These individuals seem
to have never heard of data files - like in a legal office, the
client records don't need to be kept since everything in published
law books is how to start all over again after a fire.
Is this attitude common in industry? Am I wrong? I know that
my wife has a cousin who works for an accountant who
NEVER makes a back-up of the client files.
If I am correct, is there any way to get my point across or is
this a Catch-22 situation?
Odd questions, perhaps:
Was there ever a commercial 32-bit machine built with 2901s? Other bit
slice devices?
What is the longest word length machines done in bit-slice?
Is there a practical limit to the word length of a 2901-based machine?

I wasn't there when they tried to repair it. So I don't know if they checked
the voltages after they saw it shut down in the first place. But they where
pretty sure that the error is somewhere in the control circuits and no one
(me included) wanted to touch those. :-)
Especially after someone (who should know) told us that it's extremly
difficult to fix such a PSU even if the schematics are available...

I've seen PSUs not start up at all without load, but a PSU which starts up,
detects that there's no load and shuts down again?
Of course that would explain the large amount of control circuits...
I'll add a dummy-load and try again.
I think it could also be possible that the computer somehow has to tell
the PSU what to do...

The UK. A friend of mine went to work for them for a while in the late
'80s, but I know very little more about them. Except that they made some
quite cool black terminals, one of which I had until recently.
