Some might be surprised how many systems are still running on AS400s. IBM still makes and maintains IBMi, the modern iteration. My last company wrote our flagship product for these machines, all green screen. Our customers would sometimes move to our GUI product and jump right back to the prompt menus. Hey, if you gotta move fast and have a bulletproof system, text menus are the only way to fly!
By my god, the skill set for running and programming those beasts touches on almost nothing I've learned in 30+ years of IT work. Wish I had got experience in that part of the company, seen some solid job posts for that sorta tech.
I worked with an AS400 while in vehicle logistics, those things are optimized for simple functions but high data throughput
I worked in the airline industry for years and learned a GUI overlay for one system and another entirely green screen system called SHARES (see if you can guess the airline). Honestly I kind of enjoyed working with those systems; there's some refreshing "back to basics" feeling kind of like driving a manual transmission.
In my current job I've been using another legacy system. Well, my job was to create a relatively modern service for the legacy system to call, but none of the remaining developers knew how to use the extensions of that system that does SOAP calls. So I had to learn just enough of that legacy system to hold their hands through the parts that call my service. Kind of fun, to be honest!
People keep saying to keep these XP machines off the internet. I seriously doubt there's much threat, especially for even older OS's like 98 and 95. It's the very devil just trying to browse with them, nothing much out there is going to be able to attack them. Security through obscurity indeed!
In any case, we're no longer in the Wild West days when people had machines hooked directly to the internet and a firewall was a third-party addon. LOL, ZoneAlarm anyone!
We all have a basic firewall built into our routers so unless you deliberately expose services you're fairly bulletproof to scanners. I remember scanning for Win2000 machines in blocks of IPs, long after it was defunct. Plenty were out there!
You are forgetting targeted attacks. A blind attack would pretty much not have much of an effect indeed, however if the attacker knows the machine, then it's easy for the attackers to exploit these vulnerability if left "out in the open", and cause havoc, possibly create a lot of damages or leech informations pumped into those machines via old Windows installations.
For a business sure.
You wanna hack my dnd campaign and some pictures of my cock? Sure whatever dude. All financial and important shit goes through my phone anyway and that's likely to be hacked from the institutions I use.

I was tearing out ancient infrastructure for a new office and my eye kept going to a rectangular square box on the wall. Finally realized it was a PC! The cause of death was clear, PSU fan died, killed itself from heat. It was a form factor I had never seen, but standard nonetheless. It was running an answering machine system in DOS, still worked! Such a rare machine I've only found a single reference on the web and a single video about it. 1999, 486XS (I know, would kill for a DX, it's soldered on), upgraded from 2x 2MB SIMMs to a whopping 2x 64MB SIMMs. Imagine what that would have cost in the day!
LONG story, but I got it running Windows 95b. 3.1 was just too much challenge to get it networked and happy. Much pain was removed when I got a USB floppy emulator. Can't do jack without a floppy! Broke the network card drivers, need to start over. Had it running Doom with a legit SoundBlaster card and could RDP into over the network.
It was an amazing journey getting it all together and updated. Most of that knowledge is gone from the internet, and I sure don't remember all the tricks. Going to be my first token ring machine! LOL, had to get parts from Romania and trash cans.
I binge people doing this type of thing on YouTube lol. I miss working in the industry

I would bet there are still a few old pieces of industrial machinery around that I duct taped together by imaging an ancient PC and transferring it to a Virtual Box VM.
There are many, many machines out there running 95 and even earlier versions. The issue is that a machine from 30 years ago is almost always still using the software that came with the machine… 30 years ago.
Even if the OS has received security patches, which isn’t even assured, the company may either no longer be in business, or charge for new OS drivers/specialized software.
In many cases, your options are literally to replace an entire machine worth hundreds of thousands of dollars, or deal with the networking nightmare that is “keep this on the network, but not on the network.”
BART wrote a PDP8 cross assembler in the late 90s, that they still use today.

I 4 years ago I remotely reinstalled Wonderware and necessary drivers on a Windows NT3.51 HMI controlling a mango line in Africa (I don't remember exactly, maybe Burkina?). Not fun, there wasn't much documentation left.
One year later I had to do it again.

Good for them. If it works, it works. I wouldn't connect it to the internet though.
Stuck?
“Stuck”
Imagine being stuck using something that works for 30 years.
Right? If it still works then it still works.
If the article was talking about anything other than tech/software, we’d be praising its longevity.
I mean, you could read the article. Many users are unhappy with the performance or reliability.

It really depends what its used for.
Anything that is public facing would never work without constant maintenance and upgrades, be it a computer OS or some complex piece of hardware.

If it serves their needs then more power to them. Tech companies today more than ever make sure you keep buying.
If not for DX10 and above not even existing on it, afaik, I'd still be using XP. That was the best iteration until they forcibly made you have to upgrade if you played games (especially if you wanted to play Halo on PC).
especially if you wanted to play Halo on PC
I still giggle that after years and years of Halo 3+ being a console exclusive, and Halo 2 sucking on Windows for years*, the entire Halo collection now has a Gold rating on Linux. I have very specific memories of being annoyed for years that the most prestigious Microsoft game doesn't work on a Microsoft gaming platform (Windows).
*God damn does Games for Windows Live suck
At my old workplace, there was numerous XP machines still going. They were running old machine equipment, and basically served as a controller for the entire machine.
As it turns out, it was cheaper to keep these XP stations, instead of buying a completely new Hydrolic press, or whatever it was running, which cost several hundred of thousands of dollars.
One day one of these computers stopped working, and we immediately tried to get the software to work on a brand new W10 replacement. Took us a week of drivers hell, until we eventually went to the basement, found an exact replica, and swapped the HDD over.
The company, making these heavy machineries, went bankrupt in the early 2000s, and there was literally no way of getting the software to run on anything besides that original box.
I'd like a law that software / hardware companies who file for bankruptcies must release the source / files for their tech to an open source repository.
That idea often comes up in these discussions and I've never really had an argument against. Best I got is that parts of that software may have moved to more modern stuff that was purchased by another company. But that's a damned thin excuse not to implement this.

I set up a 32 bit Windows 7 VM so my dad could keep using his old drawing program that was built for Windows 3.11.
It was the last version of Windows to support 3.11 compabillity.
Works well.
Just a note: Windows software for controlling hardware is highly likely to assume a)direct access to the hardware (sometimes mediated thorough ancient APIs and assuming the existence of defunct expansion slots) and b) assume meatspace time can be counted using OS timing ticks (which get stretched out as modern VMs timeshare with other processes underneath the virtulized hardware). It is awfully tough to replace them sometimes.
Yeah, I suspect you gotta do something similar to what McLaren did when the special mid 90s computer they used for the F1 got too hard to replace as they broke, they built a new computer interface that was compatible with modern computers and allowed them to interface with the car

There are third parties that create new software for old industrial machines for this exact reason.
There's still things like that on my workplace today. I think there's some older, rarely used CNC with Win98 on the controller. We just keep spares around when they break, but that's cheaper than replacing the whole machinery. Also there's some XP stations running software for an industrial machine which would cost quarter of a million to replace. Some of those need access to network drives and such but they live in a strictly isolated VLAN.
And, as far as I've told at least, there was no option at any point to upgrade just the computers on those things. It's always the whole assembly line or whatever they're connected to. There's not many companies willing to throw hundreds of thousands every 3-5 years to replace perfectly working equipment.
there’s some older, rarely used CNC
Me over here with a dirty mind 100% positive that I'm not using "CNC" the same way you are. I don't know what your way means, but my way is more fun.
CNC—computer numerical control, where a computer makes the cutty/smushy/printy parts move through meatspace.

Yup. Take backups, have spares, and keep it off the Internet and it'll work just fine.
Pro tip, you can get IDE to CF adapters if you want to put an SSD in those old machines to really see them fly. Just be aware that they don't have nearly as good write durability as a real SSD, so keep write heavy operations on the HDD.
You can get industrial grade CF cards that use SLC memory. They have much better write endurance than normal CF cards.
Yeah, and as long as these things never touch the internet, there really isn't an issue.

The dot net framework was ported to Windows 95/98 so they can use more software now.
Mail sorter for a company I worked for uses Windows 3.1.
My parents ancient HP from 1997, I sold the motherboard with popped capacitors for $250. I informed the buyer of the condition and he said he didn't care, he'd fix it, but they needed it for some legacy hardware their company functioned on.
😂 🤣
Similarly, my Dad ran his medical office on Win98 until he died (2011).
Of course, he had no support for OS or the medical office software other than himself (and me).
Had a supplier of inexpensive old machines/parts.
All cause he refused to pay the $5k required to upgrade the medical office software that ran on those machines. 🤷♂️

Stuck or preferred choice?
Trapped using software they needed to buy once, vs rent?
Yes, stuck. There are enourmous problems with different institutions having to use ancient PCs because the software doesn't work on modern ones, be they electron microscopes, hospitals or industrial machinery, causing e.g. enourmous security issues. This is one of the most important reasons why FOSS and why making FOSS software mandatory in government contracts is so important.
Also how come people can't read the fucking article before commenting?
