I'd be surprised if the RJ45 was a different pinout from the one used on every Cisco router and just about everything else. Converters are a dime a dozen.
Does the version of linux in that link support the crypto engines in the Octeon? There are content filter engines (hardware regex) as well.

You write "decent," "song/instrument recording" and then "<30$".
I think you are missing some zeroes there.

If you use a directional microphone you can avoid picking up noise if it comes from off-axis. The word to look for are "hypercardioid".
There are high-end microphones that can use 3.5mm jacks, but they tend to do so via adapters. Not all 3.5mm inputs are the same, some provide "plug in power" and others don't. But anyway duck is right, the preamps in it are not going to be very good. You will get better results by going to a separate preamp, or a mixer.

All of the Silicon Graphics MIPS cpu workstations support stereo graphics, except for a few of the least-capable like the Starter Indigo and the 4D/70G. API support is an integral part of GL and OpenGL, there are no "drivers". The application simply requests a stereo mode. As a consequence, the number of programs that support stereo is something like "all of them", including most of the screensavers.

They were intended to be used with CrystalEyes infrared shutter glasses, which were the industry standard during the '80s and '90s. Shutter glasses were made at various times by other companies, but the chance that any of them were actually tested by SGI approaches zero. CrystalEyes supplied connections for half a dozen workstation vendors, including Sun, IBM, DEC, HP, and Intergraph. From this you can infer that they all provided the stereo signal in the same format: only the connectors (and in one case, the Vcc) were different. These were professional products for professional users, which normally cost over $15k for hardware and something similar for whatever software was in use. It's possible that you could connect consumer-grade glasses like that web page describes, but in 18 years of using unix workstations I've never heard of anybody doing it or verifying that the schematic is correct.

There, FTFY. The stereo display is a built-in system feature and correctly-written software supports it. To get a depth effect, a scene must be rendered from two different camera positions, so an application must be written for stereo no matter what API is in use.

Is this the Presenter card you're talking about?

Yes, that card has the stereo glasses port. There were only three cards made for that special 'graphics expansion' slot in the O2: that one (for the Presenter 1280 OHP panel or stereo, not both at the same time), the 1600SW LDI adapter, and the VGA dual-head adapter.
The stereo port is a minidin-3, same pinout as VESA standard stereo, but with about +12V instead of +5V on the power pin.
You can use CrystalEyes Wired, the E1 or E2 emitter, or something called "NuVision 60GX":

(The table gives the mistaken impression that other configurations are not supported as well: e.g. VGX and Onyx use the Powered Peripheral Port; Personal Iris Eclipse uses a pin on the Genlock Option DA15 port; and Octane V6/8/10/12 use the standard minidin-3 port. They misspelled Indigo2 XL and XZ.)
(Edit: I just noticed that it is also wrong on the "Octane/Onyx2" line: the port is DE9M, not female.)
I searched for other models of VESA-compliant glasses, but they seem thin on the ground compared to proprietary solutions. All VESA glasses and emitters should work with the SGI if they are tolerant of a range of supply voltage.

Well, if you don't often need floating point, COP1 emulation is certainly a solution. But since the MIPS FP registers are inside COP1, the code needs to be carefully written so that whatever variables store the emulated registers are context switched the same as the int registers.

Don't lose a screwdriver in that 490A bus bar area!

Looks like the Hardware Developer Handbook is wrong.

The Suns I have are real old:
One 3/60 without color
Two 3/80s, with two mg2 and one cg6
Three Sparcstation 1s
A Sparcstation ELC with a spare 40 MHz cpu board

Nothing that exciting, a couple of LCs, a couple of LC475s, a II, a IIsi. I've seen pictures of HUGE hoards of machines and it seems that since Steve's death some prices have been going stratospheric. Like insane thousands of dollars for Apple ][s and Lisas.

Watch out with the 840av, those are also subject to extensive corrosion from leaking SMD electrolytics.
(Like everything Apple introduced between 1987 and 1993)

There are some cool machines on that wiki. I have wanted an Ann Arbor Ambassador for years, but I don't think there are any left.

The O2000 and Onyx2 (and by extension the Octane and Tezro) are based on an academic computer design from Stanford called DASH. There are many papers about it on citeseer. This design uses directory memories to produce coherency from a loosely-coupled mesh of processing nodes (each of which has several CPUs in a traditional SMP arrangement).

I think that the Octane and Desktop Tezro only have a single node, either with 2 CPUs (for Octane) or 4 CPUs (for Tezro). You would think that the Rackmount Tezro is really an O350 so it would support multiple nodes, but the second brick has graphics and I/O only, no CPUs.

changing the block size is pretty easy and is probably something you can do from Forth. My skills in it are not up to that unfortunately.

Octeon Plus has 128KB shared L2 cache. The Octeon II has 4MB shared L2.

If you have a fibre channel hba on an sgi, you could fx(1m) it. It is very straightforward to do.

Memory speeds are in nanoseconds, not megahertz. 200ns or faster will work, although the squirrel.com page notes a problem that had been experienced with the M48T02-150 in SparcStation 2s. Today only the faster speeds (like 100ns or faster) are being made. In fact it's a little surprising that such an old chip is made at all.

hitachi 15k600?

There seem to be many stories of Seagates having short life expectancy, although "the plural of anecdote is not data".
I don't run many drives in service, so I don't know which is more reliable: but both modern Seagate and Hitachi drives are quiet and cool.
I did have an unusual experience with one Hitachi 7200rpm disk:
viewtopic.php?f=8&t=16729231&p=7375242
It still does the same thing and has not failed so far. I definitely wouldn't want to use this in a RAID array, but my hunch is that it is a drive configuration problem.

IP28 supports a 64-bit kernel, IP32 does not.

13w3 connectors are available from ITT Cannon, Cinch, FCT (Molex), Amphenol, CONEC, FCI, Harting, and Phoenix Contact. Remember that you need a connector with 3 coax pins; don't get power pins by mistake. The type with solder cups is more expensive, so crimp tooling is the way to go.

With slow floppy and hard drives, there's really no reason not to bite the bullet and do your work on a shared volume. All the things that seem inconvenient on those computers due to lack of space are pretty trivial once you have gigabytes of shared volumes. You could even use an SGI with netatalk as the server (but that does require a LocalTalk bridge, I think: unless the sgi's rs422 can be tricked into speaking LocalTalk)

You need to follow the kickstart procedure. A chip from Mouser is unlikely to be fake or discharged.

from my reading 20 years ago when they were introduced, I think I remember that every iButton has a 128-bit serial number permanently burned in. there are many variations when you go beyond that, with eeproms, smartcard-like crypto, and even full Java interpreters but I don't know if the latter are still available.

There's some irony because 6.5.22 was itself missing some components that SGI no longer wanted to pay to license (like Display Postscript). But pretty much all commercial Unix products included code from AT&T, Microsoft, and Sun or OSF.

looks like the directory /dev/fbs isn't getting mounted. MAKEDEV?

Anyone ever seen the 29" IBM CRT monitor? I was going to pick one up once but it was too heavy for me to carry.

I was looking at pictures of one of the Solbourne keyboards, and I couldn't figure out why it has both two minidin-8 ports (like a type4) AND ALSO an RJ12 jack. How does that work?

without a switch, you can use a crossed-over stp or cat5 cable.

Use the CLI, Luke.

The predecessor to Altium, Protel, might run in SoftWindows95.
There are some IRIX-native EDA tools, but Solaris and HPUX were what those companies mainly used, for systems like Mentor Graphics, Cadence, and Synopsis.
I know that Alliance and Icarus (free software tools) have been ported to IRIX.

It looks like a response pager.

Yeah, it might be some kind of pendant/industrial machine controller.
I first thought it reminded me of this:

no hits at all on the product, but Pentica was an Australian maker of in-circuit emulators.

Dual-boot OS9 and 10.4, you mean? I don't think there's any partition magic required, the switch is handled in OF.

Not all FDDI cards can attach to both rings (Single-Attach Stations only have one port). So a network that used both rings at the same time would not be able to communicate with SAS. The way FDDI is designed each DAS station is in a particular "ring-op mode", using either Ring A, Ring B, Looping A->B, Looping B->A, or isolated. The protocol defined how it chooses a mode and recovers when the other ring is reconnected.
You also cannot have full-duplex 100Mbit with FDDI unless you use proprietary systems (like DEC Gigaswitch). The normal ring is not switched and therefore half duplex, and so are normal concentrators.

Did you ever see equipment for FDDI-II? It was supposed to have rate-reservation/isochronous features for video delivery systems. I've read a little about it but never seen the hw.

Archive.Org seems to skate under the Fair Use defense for everything that they do. Mirroring web pages without prior permission is not sanctioned by the copyright laws either.
They have a project to upload and share every CD-ROM ever published.

SGI actually sold 802.11b/g surveillance cameras during their last years (around 2004). I can't see any reason you would install analog CCTV for that purpose today.
