Finally.... proper Desktop Capture of my Octane Succeeded!
So I finally setup my SGI Octane... and it runs great still... and I FINALLY sorted through the three different devices that I bought about two years ago in the hopes that one would actually work to convert the VGA Sync on green into a signal that would be recognized by one of the VGA to HDMI converters.

The winning combination was one of those cables that convert 13w3 sync on green to VGA... BUT... has the switches that turn off the Sync on green. This did allow one of the devices to see the VGA input.
The Extron RGB-HDMI 300A  did successfully take an input which could be sent out to HDMI and would read into a cheapo 4K UltraHD USB3.0 capture card.

Captured the desktop this way using OBS and then imported the clips into Premier... corrected the aspect ratio... and finally... I can make vids for my channel that aren't just a phone sitting on a tripod.

Now I can make proper vids for the SGI / Irix and the Software running on them.  Cool

Looks great. Especially on a 4k display with YouTube set to 4k manually. looking forward to more content! Just subscribed to your channel (as Fritz).

Thanks for the sub... I think I will start with showing how I run Mayaman with Maya 4.0 since it was requested in the comments. 
Then there is a request for Houdini 5.5 which... I wouldn't mind doing another Houdinin 5.5 vid since the 1st one had such bad video for some reason. 

Though, I am trying to figure out what I could do for each tutorial that was already created with the Phone on a tripod. The same vid more updated?
Or maybe I will just do other parts of the application I haven't covered already.

I had always intended to do a general Irix OS tutorial showing program installs, usage of the Terminal with some commonly used commands.
Networking was always a big question... maybe show how I have that setup as well.

Honestly, we get enough questions for basic installation that if you really wanted to get that end of things that would be immensely helpful. Just shove a brand new, new old stock, hard drive in and record yourself going through the perfect install in standard 6.5.22. I’m obviously including partitioning in this entire demo idea.

Your video could just become the reference that we put when anyone asks about how to install the operating system. Just throw your YouTube link so at least you get those viewers.

The installation instructions for 6.5.30 are available online, Ian for example: http://www.sgidepot.co.uk/ - The instructions didn't change much, if at all, between 6.5.22 and 6.5.30

RE: Finally.... proper Desktop Capture of my Octane Succeeded!
I can't tell if you're joking or not, so I'm going to assume you're actually serious.

If you started to notice those instructions have not been enough for several newcomers we've recently experienced and I assume this is an age related thing above all else.

Ian's instructions are the most complete anyone's actually publicly written for everyone to see, but they're not numbered steps nor is following them literally going to address resolving the two or four conflicts that I remember that always come up around Java and Mozilla and what not. It also doesn't talk at all about how to properly install SGI drivers for add-in cards that aren't normally detected automatically. It doesn't talk about the graphical desktop at all nor does it talk about things like creating a user account.

I don't want to get into a stupid argument about how today's kids need videos and all that crap. But I am saying that a video would make it more accessible to newcomers until somebody writes an installation script and publishes it for automated/unattended installs.

My personal opinion from observation is that there's more that we knew intrinsically because we actually lived through this era. If you had a workstation PC and you were generally knowledgeable about corporate computing bac then you knew about parallel SCSI buses, you knew about hard drive volumes, you understood basic networking elements, and overall you sort of had the proper expectations.

We have people coming from Windows 11 to try to load an SGI that straight out of 1995 & Jurassic Park. It just looks too alien to new/young collectors that are interested.


If someone was willing, it would be a great idea to just link Ian's installation instructions in a YouTube video description then go ahead from PROM and properly type in the necessary commands walk-through the basic FX commands we all expect people to just do, start the install and progress through it along with resolving the conflict and doing first startup. Also telling people what's you're going to commonly see if you don't have ethernet plugged in, what's going happen with the default Apache in mailbox errors at startup and all that stuff and probably how to use chkconfig to turn them off.

Logging on for the first time in the graphical environment and seeing where the tools are. Being able to make yourself a basic user account and also showing you how to add additional discs and mount them using the graphical utilities.


Just what I've described alone could allow us to just reply to everyone's initial inquiry of how you should install the operating system with a URL to a YouTube video. Yes I realize in the video they can't say where they got the files from. You also have the issue of whether you're doing a CD install or a network install. I'd recommend the CD install first and then make another video with the network install but that would just be me.


You and I may be used to these kind of instructions, we figured it out based on these instructions, but we were also there at the time and could sort of read between the lines and intuit it and also understood what might be reasonable versus selecting random options and just keep saying "go" or "continue". Which is what new younger people today will actually do. See they're used to highly controlled environments like iPads and whatever that keep warning you if you're doing something wrong or prevent you from doing destructive operations. That wasn't what computers did before, especially in our generation. So you and I might stop and think about a question that we have and perhaps do some quick research on it but you would be shocked that most young people would actually just barge through it like it's a unwanted ad you click no or cancel too. They don't think about the fact that there might be lasting effects because in their minds almost everything you could wrong you can just go back and change later. To some extent that's kind of true but for most of the decisions in the SGI installation that isn't true.

So while you may have initially dismissed under the thought of why in the world do we need a video of instructions when we have a several sheet guide of written instructions? I would easily counter that those instructions are no longer adequate for a newcomer that is say 25 years or younger who wasn't exposed to computing from the early 2000s or the late 1990s.

There's a difference between hand holding and making a guide, obviously I don't expect a YouTube video to go in depth on SCSI... But I would expect it to say that the machines tend to use ID 0 for the controller and that you should be using ID 1 to boot from. I'd also expect them to fast-forward through loading screens or things that would be unnecessarily long and boring.

But that's the basic reason I asked, we can shove the SGI depot instructions into anyone's face but if they're not a seasoned computer user from the late 90s they still haven't seen a bunch of this stuff. Basically once IDE/PATA dropped off the planet... These parallel ribbon bus connections are now foreign to people who grew up with computing after about 2004. It would also be important in the video to set appropriate expectations like how fast the network connection is and how fast the data connections are. We're talking about orders of magnitude slower than a $300 computer I can buy today. It's appropriate to set the stage and help the people through it so they can get something that immediately works they can play with then they can decide if they want to really learn or if they did what they wanted to do and they wanna just sell their system and pass it on to someone else.

RE: Finally.... proper Desktop Capture of my Octane Succeeded!
Thanks for the insight into why Ian's info is a bit TLDR for the kids these days. 

I am pretty stupid overall so if I can figure out how to do it, I should be able to do the caveman explanation version in a video. 

Though, I wonder... first I would need to acquire a new Hard drive and then maybe,
what, use another computer networked to the SGI to do the install?

I have never tried to do an OS install. Always just ordered drives with Irix already going on them.

Though this would make a useful vid for sure that I am interested in making for all future SGI hobbyist posterity.

RE: Finally.... proper Desktop Capture of my Octane Succeeded!
Well first off it's incredibly easy to get an SCA 80 SCSI hard drive that works in an octane. Those are still $40 or $50 drives all day long on eBay.

Personally I would not go for the network install because it requires knowledge outside of the installation itself. I would eventually do a network install video but I would do the CDROM one first.

Now since the Octane has two buses you could easily attach a narrow bus ZuluSCSI to the external port on the octane and place a bunch of CD images on it and use that as the CD install. Personally for the video if you were actually recording your workspace and not just the screen output having the CDROM discs themselves and the real drive would have more effect and theatrics, but if you don't actually own those I would understand.

I would do the CD install first because it is the most core, vital, understanding of the install process.

Then if you wish to explain to people how basic networking works enough to run a virtual machine that has the network install helper utilities on it, then I guess you could go ahead and do that but I would only do it after installing using discs. The disc install is the most basic and most often utilize installation, network installs where the domain of university campuses and such.

Plus the network install still requires knowledge of how the CD install would've gone, so explaining the order of opening the CDs and stuff like that is still just as important and it makes more sense if you're talking about physical media then about directories on a network.

RE: Finally.... proper Desktop Capture of my Octane Succeeded!
Eek, my old pages stirring the mud. Biggrin

Is it the vanilla 6.5 info page you're all referring to? ie. this one?

http://www.sgidepot.co.uk/6.5inst.html

True enough, there are many aspects it doesn't mention, the GUI stuff, user accounts, etc., but then a lot of this is covered in my Unix Admin Course. Wink

I did create a different document that was included with custom CDR sets, namely this (plus an equivalent for 6.5.22, just change the URL to see the equivalent file):

http://www.sgidepot.co.uk/sgidepot/6.5.30instreadme.txt

Since it uses product selections files, included with my Gifts CD, it means there are *no* conflicts to worry about, and it covers a lot more than the above old page does.

What I could do is add the product selections files to my Depot Resources page for anyone to use, adapt the file into a more general guide.

Btw, the install topic aside, it's interesting what Weblacky is saying about the apparent perceived need to cater for "newcomers", it shows how the nature of the SGI hobbyist landscape is changing, but I suspect some may see some aspects of how people think things should adjust as a sort of dumbing-down of expectations. I'm not sure it's wise to alter too much the nature of things to pander to a "controlled environment" generation who, if that's genuinely what they're used to and find contrary environments uncomfortable, won't exactly take so well to the inherant nature of older computers anyway. One could make the argument that the basic nature of how older computuers were used, what one was expected to know or at least learn if need be, just is what it is. One can adjust to some degree of course, but the hand holding can go too far. Better perhaps to say, put the ipad down, if someone wants to get into these old computers then surely it's logical to delve into the mindset that surrounded them at the time in an authentic manner, if that is such is the goal. Otherwise the experience is a sham, an illusion, like a West World resort.

I often say in emails that a mistake many hobbyists make is dismissing the command line shell, because they're too used to GUI stuff. Pandering to a 'modern audience' in the way described would just make that worse. It doesn't have to be an either/or, but getting to know what these systems were really like at the time and how they were used in the way they were surely has merit, because that's a fundamental part of what they were (I've dealt with a great many ex-company machines, usage via the shell was very common). Otherwise we end up creating a fake notion of what SGIs were (or anything else), because it gets layered on top with modern simplified modes of convenience. Yes some pro uses of SGIs were all-GUI, but others were not; some presented only their dedicated interface and nothing else (the user never saw the underlying IRIX at all), like Discreet for example, others required the use of IRIX. I talked to company folk who didn't even know they were using SGIs.

I don't think the next generation is that dumb. Not only do I think they are perfectly capable of learning "the old ways", a great many might actually find it both a refreshing change and very educational, because that is surely part of the whole thing. Afterall, these days there does appear to be a pushback against the scale and depth of the tech explosion going on, attitudes are shifting. Let's not underestimate Gen Alpha's capacity or desire to learn; they may actually prefer the authentic experience, rather than the sanitised version. Beware of misplaced altruism.

The early 90s was a huge crossover point in the nature of many technologies, especially storage. The shift from tapes and floppies to other things, for example. If we disuade newcomers too much from delving into the nuance of how old systems work, how can we ever expect them to gain any passion for the even older or complex stuff like 4D Series, Onyx, Challenge, Crimson, PI, etc.? It would be a shame if the SGI landscape shifted just to the "easy" systems like O2 or Indy on the back of thinking one ought to reduce the complexity from a belief that unfamiliarity with old ways precludes an ability or desire to learn them.

I think it's better in general to preserve the nature of what SGIs were in their original form, encourage those who want to learn about them to do so in context, because otherwise much of the contemporary usage nuance of the 1990s is lost. I understand the appeal of modern addons like SD card adapters and all the rest of it (I've used ZuluSCSI), but going down that route as a norm means removing from the SGI legacy fundamental aspects of what they were and how they were used. Back in the day, people had to deal with DLT, DAT, QIC, etc., then later CDROM. It concerns me that trying to make everything too "easy" may dilute what ought to be the option for a more original experience. It's the same with modern emulators for consoles like the N64, or old home micros like the C64. I'm glad they exist for those who want to use them (with obvious advantages for modern coding), but I prefer to use original hardware because for me that was and still is fundamental to their appeal. I think SGIs are in a similar position, they are a manifestation of an era of tech that was in transition; how they were used at the time is a part of what they were, and thus of understanding their nature. Also essential for some of the machines which are just inherantly complicated.

I intend creating a guide on how to install IRIX from hard disk. Afterall, it's how I do it; largely automated, no CD swapping, very quick. But the experience is very different to installing from CDs, using a disk doesn't provide the same sense of what it was like to install IRIX back in the day. The guide will be useful for those who just want to get it done, but not what I would recommend for those who want to learn about SGIs more broadly and experience them in a more authentic context.

Hence I think we need to strike a balance, conveyed in some manner so that users understand that although there is some option X to get something done that is easy and quick, it isn't how it used to be done, it's not the authentic experience, so if they want the latter then there's also option Y; and often variations inbetween.

What people want from SGIs varies enormously, it's a vast spectrum. I've talked to hundreds down the years; some use SGIs in a way which would not appeal to others at all. Some care about the hw, others more the sw or coding. Some just like the aesthetics, others relish the challenge of restoration & repair, after which they sell the systems on or give them away (using them isn't for them, they just like fixing them up). Some like to install the OS from scratch, they want to understand how it works. Others just want to get a setup ready to use straight away with everything preconfigured (that's the crowd I mainly cater to). Some just want to run specific pro applications from long ago, others want to learn about the OS. These days some are retired professionals, they used SGIs back in the day and want to relive those times, they already know about them.

Thus, there's nothing wrong with presenting a guide that enables an easy method for installing the OS, but I don't think that should be the encouraged norm. However, that doesn't mean my old guide can't be improved; heck, my entire site needs a revamp, it's awash with dead links (plans underway).

Lastly, I have to point out the irony of modern modes of information provision (like YT) being of a form that cannot actually be viewed on an SGI. Biggrin This is why my site remains stubbornly plain old HTML, though next year there may be the first links to video content that's offsite, or downloads that need a PC or whatever to play them (I have many original VHS tapes to digitise).

Ian.

RE: Finally.... proper Desktop Capture of my Octane Succeeded!
Is it possible to easily make a "super image" for the scsi emulators that has all of the CDs for 6.5.30 (or .22 etc) in a directory that would negate the need for CD swapping?
