Not possible, at least not in a deskside. Only 5 E-bus slots, and you need at least one for memory, and one for I/O. So max is 3 CPU boards. I'll have to settle for 12 * R10K 8-)

But they will be the 2MB L2 model.

Me too. It's just a curiosity thing; I have both the L and the DM sitting here so this is the perfect occasion.

I could simply install the R10K boards in the Challenge L and call it quits but that wouldn't be satisfying. I need to know how things work and how to hack them

Looks like jj's got the quiet 0300 covered: viewtopic.php?f=3&t=16718040&

Two things:
* Change all of them. It is a pain to take the PSU apart, but if you don't you might as well forget about it entirely.
* The fan I used has been discontinued. There's the S-FLEX SFF80D (2,800 rpm) but at 32dB it louder than the NMB Minebea I used (28dB), and I believe the bearing had a shorter MTBF as well.

See:

It's designed for car paintwork but does wonders on other surfaces aswell.

I bought a 150g tube from B&Q , was about 5 UKP. Practice on some plastics you don't much care about first, get
used to it. Use it too much btw and it will discolour the surface.

[...]

PS. Some of the above solvents are toxic and damaging to skin, lungs, etc. Be careful if you use any of
these things. Well ventilated area essential.

I use a cleaning agent made for cleaning stainless steel in kitchens. It's an abrasive, fine powder ('white clay'), not toxic, doesn't dissolve anything. I got mine from one of those "eco" / "bio" shops.

It works best to remove scruffs: http://vdheijden-messerli.net/sgistuff/ ... .24-skins/

Just for kicks I give it a try on a pair of totally scratched O2s. Here's a photo after I treated the worst of the two: viewtopic.php?f=3&t=16721530&p=7305524#p7305524

As with any scraping agent: apply too much or too long and you will have no texture left. Also not really suitable to remove scratches deeper than the texture on the skins.

Several of the IP numbers you mention did exist: http://old.sgistuff.net/hardware/tables.php#ip

The rest probably never made it to a real product. Which makes you wonder what happened between IP35 (Fuel) and IP53 (Tezro).

zuluchas wrote: This is interesting because the power supply is only rated at 1050W. Perhaps the VGX transplant is too much for this little guy? It certainly makes a 16-gauge cable warm (so I've switched to 12).

The 1050W number is the combined output power (U*I) of all power modules of the PSU. You have to add the power lost in the PSU to calculate the power drawn from the net. I believe they are quite efficient especially considering their age, but even (let's say) 80% efficiency means it generates 200W heat inside the PSU. There's a fan in it for a good reason!

There is another rating (1500W) for the max input power the that the primary stage can handle.

These two numbers for the same PSU, combined with the fact that you have to disassemble quite a few parts before you can even read the label, has led to endless discussion threads in comp.sys.sgi about "RealityEngine capable" PSUs and which system configurations would need those. In the real world, my 4D/440VGX consumes significantly more power than my Crimson RE.

At least, that's how it is for a single tower PowerSeries. Here's the label for the PSU of one:

Looking good! I see you've got a PCI cage, but it doesn't show in the hinv (XTALK_PCI)? A hacked 3c996b-T card would be a nice addition to get gigabit ethernet on the cheap.

Thanks all! I'm pretty excited about this. Interestingly, the seller went for my price on the RM10s, but not the GE-16. Doing some searching, it appears that I'll be able to mix the RM10s and my older GE14-4 for the time being - is that correct?

Yeah, I ran my previous Onyx2 with a GE14-2 and two RM10's for some time. Ridiculous combination but it works fine.

bigD wrote:

Could it be because I don't actually have any PCI cards installed? I'll look into it, and cheap gigabit sounds good to me.

No, it should always print the XTALK_PCI near the top of the hinv. Try to reseat it, that might be enough. Otherwise, inspect the backplane for excessive dust where the compression connector mates, or scavenge a compression connector from another XIO card.

Wow that's bad.

An O2K/Onyx2 module uses ~ 25W when powered down, but the breaker in the back engaged.

It also has a hideous power factor of 0.25 or so when powered down, when running it's 0.97 or so.

Subject: -75- Why does my GL application run slower on newer SGI hardware than it did on older SGI hardware?
Date: 8 Mar 1997 00:00:01 CST

One probable explanation is that your program is using IrisGL (sometimes referred to as just "GL") rather than OpenGL. Starting with Impact graphics, SGI graphics hardware is optimized for native OpenGL. IrisGL calls are executed through an emulation layer known as IGLOO, or "IrisGL On OpenGL." This layer of emulation reduces performance.

The best solution is to port your program to OpenGL

Yes, I was talking about hardware.

Here's a paper about the design of the RealityEngine by Kurt Akeley of SGI. Even though the original RE was introduced in the IRIX 4.0x days, this paper talks about OpenGL. Then again, I assume they didn't design OpenGL on a Friday afternoon

It's got a couple of other issues, so before I decide what to do with it, I'd like to know if there's anybody out there willing to sell/trade me an RM. I've got *lots* of SGI bits and boards, so if you're looking for something let me know.

SAQ wrote:

We should be able to scrape up equipment for test builds here - I personally have a Challenge R10k that has a 6.2 system disk option.

I've been doing this for while, but you must not underestimate building GCC. First of all you need a dozen or so support packages in place, and a fairly complete set of GNU tools. A full bootstrap build + regression test takes the best part of a day on my Origin 300. Older IRIX means older hardware means longer build times.

Rainer Orth, who has put by far the most effort into GCC on IRIX says building an IRIX 5.3 GCC takes nearly a week for him. I cheat a bit and can do it in an IRIX 5.3 sandbox on my Origin 300 (yes: IP35-irix5.3 ) in around 7 hours I think. You cannot sandbox IRIX 6.2 inside 6.5 because nothing depending on pthreads will work.

You cannot expect "GNU" to support systems indefinitely, having been EOLed by their manufacturer for 10+ years.

So I've got the O300 in the rack at work and it does automatic regression builds. It need a bit of hand-holding to keep up with dependencies and the occasional breakage. But that's not the problem. You need to analyze what comes out -- compare results, find the source of breakage, provide patches, and be responsive on the mailing lists. In reality, I don't have the time for this. I've got a busy job, wife, baby boy etc. etc. Instead I maintain a private patch set which fixes the worst breakage and build compilers when I have the time, not on a schedule or when upstream decides it's the time.

I've got a new 12x R10k Challenge L which is almost ready to roar. I can do the occasional GCC builds on that too, and I plan to help Tom with TGCware, but again, it's not realistic that I'm going to keep up with GCC SVN HEAD.

Donating cycles to making the very best gcc 4.4.x (or 4.5.x) release possible for IRIX < 6.5 would be nice.

This is exactly what is feasible in the limited time I have available.

Try to arrange your XIO cards such that the lower right corner XIO slot is unused. It more or less guarantees fastfan mode which I personally find unbearable

Haha, until you realize how much heat an IR pipe puts out doing nothing while the machine is busy compiling

Good catch otherwise!

The newer GCC probably doesn't even run well on the older Personal IRISes.

GCC 4.x currently doesn't run at all on any machine with an R3000 CPU, and neither does any code built with it.
I have the feeling some mips2 instructions have sneaked into the crt code.

Both GCC 3.x and 4.x can consume more memory than you can install on many of the early systems, especially when compiling larger C++ files.

Normally you link by invoking the C compiler (cc), not ld directly. cc links in libc automatically.

I did s/w development back in the OS/2 days. We were so happy when Windows NT appeared. Windows NT (3.5.x) was slower, but more robust.

FWIW, it seems this redux thing is more about creating some sort of OS/2 personality / desktop on top of Linux.

Nice freebie

Assuming all panels are installed, you cannot really fry it as long as you put it on blocks so it can blow the hot air out the bottom?

Was that an "official" rackmount or a deskside stripped naked? I still have some of the Onyx2 rackmounted deskside skins / rails, if you want to properly mount it in a rack. It's not as pretty as a deskside, but the metal front has a no-nonsense "don't mess with me this is serious business" feel to it, and it solves airflow problems.

You need to release both the two screws and the two 7/64" hex bolts.
It can take quite a bit of force to release a nodeboard. Use a foot to keep the chassis in place and pull with both hands

... the fact that it works at all is a small victory

Here's what I had to do to get this far:

* The IO4 board had a Dallas with an empty battery. This makes the machine forget it's configuration and it causes IRIX to print a continuous stream of warning messages on the console -- not very handy. I replaced the entire IO4 for the time being.

* The machine was password protected, and it's security policy was rather strict. Futile once I get physical access, of course :twisted:

* The RM6 was in the wrong slot (RM2 slot rather than RM0 slot). Graphics doesn't work like that.

* The InfiniteReality FP1 front plate had been engaged rather cruelly which had damaged the connectors on DG4 and RM6. It had also crushed a handful of wires on the back side into a solid mess. I undid that, but it seems the RM6 is toast anyway. In fact, I think someone 'borrowed' an RM from this system to fix up another Onyx, and left this one in a mess.

* The GE12-4 would make 'irsaudit' crash. Fortunately, after a fresh IRIX install, GE flash and clearing the IR-EEPROM that solved itself :oops:

* All SCSI on this box is high voltage differential. I had to mod it to attach a CDROM.

* Two out of five original harddisks were dead. Bummer, but all these 2GB and 4GB disks don't add up to much anyway.

Tasks left:

* I'm going to mod the IO4 with a CR2032 coin cell holder to solve the Dallas problem once and for all. Pics will follow.

* The system controller is giving me a handful of '???' when powering down. Might be another dead Dallas. This type is still available, but I think I'll mod it anyway. I'm tired of these things.

* The hinge of the front door broke, it has been repaired but in such a way that it doesn't close anymore. I'll have to fix that.

* The system was loaded with Alias|Wavefront, ProEngineer, etc. I'll have to see if there are any licenses and other interesting bits left.

* Upgrades?

Bah, even with a professional desoldering station it seems to be impossible to remove a Dallas from an IO4. I'm going to have to think of a plan B

This batch, I assume ? Congratulations

Every unit is supposed to have a PSU and a fan tray, but they are amongst the parts that fail most often. Looks like someone gutted one or two systems to keep the rest going.

7/64 inch hex keys can be ordered online, or from shops that deal with machinery from the US (like a Harley Davidson shop).

If you search the forum you'll find some recipes to recover scruffed skins. Often an amazing recovery is possible. At least you've got plenty of parts to pick and choose, and you can recover part of your cost by selling of the remains.

I've tried it all. Even tried a professional desoldering station. It won't give in. I'm not going to push it too far and burn the PCB.

I've seen pentium's work:

I've reworked a Dallas before. This is the result (from a SUN SparcClassic):

Attachment:

IMG_2747.med.jpg [ 124.39 KiB | Viewed 125 times ]

Find the differences :lol:

Usually Dallas chips are socketed. This one isn't. Since I cannot remove it from the PCB, I'll have to rework it while it's still installed. That, in turn, means the support next to it will have to be removed.

I intend to use an SMD style CR20232 holder again like I did with the SparcClassic. There's room for one on the IO4 next to the Dallas, putting it on top of the Dallas might cause problems with IO4 mezz cards.
