Hi all! In case anyone noticed it, we had a brief DNS outage that was registrar related earlier today. Everything was running but the delegation between sh. and sgi.sh. was gone. Of course, if you are reading this message, it has been fixed :)

Does anyone have a good supplier for the 72 pin parity 60-70ns SIMMs usable as Indy RAM? Ideally still selling the 32MB sticks. I used to go to MemoryX for these sorts of things but unfortunately they seem to have gone under.

Today I was running into a problem with NFS stalling out on a copy from a remote machine to IRIX. NFS worked generally, but while copying the file it would always stall out at exactly the same place. The place it would stall was different for different files, but always completely repeatable for...

Since I have been away from home on the weekends these past few months, I have needed to find little bite sized projects that could be completed in an evening or two, and decided to give a much needed overhaul to my retro gaming setup. With NES, SNES, N64, GameCube, and PS2, most of the output...

New in box, shrink wrapped Phobos G130 - $80 plus S/H. For sale is a Phobos G130 network card for the SGI Indy (GIO32 bus), shrink wrapped and new in box. Like some of the items I'll be listing at low cost, this is for active forum users only! Please have at least five reasonable forum posts...

Someone in Discord recently asked after extracting tardist / inst packages. The tardist portion of this is easy, as it is basically a standard tar archive, which can be untarred (tar -xvf), yielding multiple inst "sw" packages. I have had mixed success extracting inst packages using software...

Discussion on this thread and previous ones in the chat have made me think once more about the "old versus new" paradigm in the community. Originally the User Group was founded out of ex-IRIX Network members because people were getting criticized and harangued for not following the one true...

This is something that I posted as a joke in chat after some contentious discussion about government shutdowns in the #hardware channel and someone noting it was off topic. I think the discussion had the potential to be on topic, if in a rather roundabout way ;) Since it was requested...

The first thing that people often come across when using older SGIs is the 13W3 video output. The one and only solution I recommend to this is the famous "DIP switch" cable that adapts from 13W3 to a standard HD-15 VGA connector. This cable is in current production by cablesonline.net, and can...

I have been working with (and having some since resolved troubles with) Tezro SCSI lately. The Tezro has a separate external SCSI bus coming off the back of the IO9 card, which uses a 68-pin "micro centronics" a.k.a. "VHDCI" connector. In case anyone wanted to use external SCSI storage on their...

Along the lines of looking at the PSU, I've also been investigating all the Tezro power rails, many of which are generated not by the power supply but instead by VRs / VRMs on various system boards. If referencing or duplicating this information, I ask that you maintain a prominent link to this...

I have always enjoyed Urban Exploration. Due to different jobs I have held in the past I have had more access than usual to roof areas, utility spaces, steam tunnels, electrical rooms and things like that. There is something about mines, underground tunnels and railways, and large industrial...

I'll discuss Tezro power supplies in more detail at a later time, but have a look at some nasty Tezro power! Super ugly. Probably needs new capacitors at the very least. Tezro owners, do you know what your power supply is doing? 😰 Also just a spoiler: there is more signaling going on...

Common wisdom (based on lots of discussions in chat) is that a more or less universal solution to storage on the SGI MIPS machines is the use of cheap and available 15kRPM 300GB 80 pin SCA connector SCSI drives, with an 80 pin SCA to 50/68-pin adapter if necessary. Specifically I am using the...

Besides eBay, Craigslist, Facebook Marketplace, Reddit, and all of the other community solutions for looking for SGI gear, here are some of the SGI resellers: Mashek Systems SGI Depot sgisun.com (Goldscholl) B&B Solutions Although the prices will be higher than buying from a community...

There was a discussion in the chat about original Silicon Graphics pricing. I've attached one of the found documents describing pricing from the Fuel, Tezro, Prism, Origin 350/2000, Altix 350 era; any others indicating original prices, from when SGIs were actively sold, are welcome! Please post...

We're here again for Power Supply Basics! This time, the Indigo (Indigo 1) is featured. The Indigo is the oldest machine I own, so I won't be covering any 68ks or IRIS 4Ds unless someone in the area brings one to examine. The Indigo was a bit of a pain to figure out, only because I started with...

This thread is for collecting links to posts about individual Silicon Graphics power supplies! Indigo Indy Indigo 2 (Impact & Non-Impact) O2 Tezro (non-PSU) voltage regulators and rails More to follow!

It's time for more Power Supply Basics! This time of the Silicon Graphics / SGI O2. This one had less to figure out than the Indigo 2 and Indy. If referencing or duplicating this information, I ask that you maintain a prominent link to this original forum post for further updates, as well as a...

As you may have seen, I previously did a writeup on Indy power supplies. I've recently examined the SGI Indigo 2 PSU, and while I won't be exploring it in the same level of detail as the Indy I wanted to share some of the basics. If referencing or duplicating this information, I ask that you...
