How I once took down a network, including a radio station
Last Updated on October 16, 2026 by Dave Farquhar I met up Monday night with some other security professionals for some emergency networking of the professional kind. One of the attendees, a penetration tester, had a little incident where he took down a production system when he conducted his penetration test. The system owners were a bit arrogant, and, well, they paid for it. I’ve taken down a network too, but in my case it wasn’t something security-related. No, in my case, I was a 20-year-old desktop support technician working in a college computer lab, making an honest mistake. Token Ring networks had one problem: The speed didn’t auto-negotiate. So you could bring up a 4 megabit card and take down a 16 megabit network. The standard-issue machine in that lab was an IBM PS/2 Model 53 SLC2, which was powered by a 486SLC2: a weird IBM CPU that added the 486 instruction set, a 2x clock multiplier, and a bunch of cache to a 386SX CPU. It was a better chip than it sounds like, but was limited to 16 MB of RAM. It was not a rip-roaring machine even in the mid 1990s, but it was one of IBM’s last attempts to make the PS/2 affordable before shifting back to industry standards. In a weird turn of play, IBM also used that CPU on cheap clone motherboards it sold to other manufacturers. Our shop was about as blue is could be back then: OS/2 running on PS/2s with Microchannel, on a Token Ring network. Microchannel wasn’t quite plug and play, my boss explained, but it was very close. Token Ring and Microchannel were two very good IBM ideas that died because IBM wanted to own them. It’s unfortunate because the industry probably lost a good five years of innovation because of that, but that’s the sequence of events. Token Ring worked well, but had one serious Achilles’ Heel: It didn’t autonegotiate. If you brought a machine up on the network at the wrong speed, strange things happened. The cards in these Model 53s defaulted to 4 megabits. We ran a 16-megabit network. So I plugged a card into a machine, plugged it in to the network, powered it up, booted off a floppy, and received a strange message: The network is busy. “The network is busy?” I scoffed. “What is this, America Online?” So I started troubleshooting. A couple of minutes later, my boss raced into the room. “Ah, you’re working on that machine. Good, I think we found our problem.” He explained that an entire network segment was down, including the school’s radio station. He showed me how to check (and change) the card’s speed with a reference disk, which verified that my machine was on at 4 megabits–and destroying the network. We changed the setting, rebooted, brought the segment back up, and I didn’t make that rookie mistake again. Today, any technology having a quirk like that would be unacceptable, but in the 1990s, things like that were common. When I start missing the ’90s, inevitably I remember things like this, and then I don’t miss them so much after that. Well, maybe.

What was a Token Ring network?
What was a Token Ring network? Token Ring is an obsolete networking technology that competed with Ethernet in the 1980s and 1990s. IBM first announced it October 15, 1985. It is more of a curiosity today, as the networking standard that lost. But when Token Ring equipment turns up, it can look enough like Ethernet to confuse people. And why it lost can be interesting to study. ## Ethernet versus Token Ring This Intel Token Ring card can pass for Ethernet. The best indicator from this photo is the DE-9 connector on the back. Ethernet never used that. Even though it was an IBM technology, companies like Intel and 3Com wanted in on the game. Token Ring gets a bad rap today, and that isn’t necessarily fair. Token Ring was a standard backed by IBM. Ethernet was an open standard backed by DEC, 3Com and others. Of course Ethernet won. The main reason Ethernet won the war was because it was cheaper. Once you bought everything you needed, Ethernet cost a third as much. Whether Ethernet was half as good or 75% as good was always a matter of debate, but for a third the price, it only needed to be half as good to be a reasonable value. Token Ring had one big weakness besides cost. It ran at specific speeds, and unlike Ethernet, all the cards on the ring had to talk at the same speed. If you had a 16 megabit network and brought up a system at 4 megabits, it took down the whole network. Here’s how I know. But I only made that mistake once. But as long as you didn’t do that, Token Ring was extremely robust. it didn’t have a problem with collisions, unlike early Ethernet. The way Token Ring worked was the systems passed a token around the network. If you didn’t have the token, you didn’t get to talk. That meant no collisions. And it handled saturation much better. I brought down an Ethernet network once just by trying to clone a classroom full of systems using Symantec Ghost’s multicast feature. I did it all the time when I worked in a Token Ring shop. The first time I did that on an Ethernet network, I took down all of the networking in the building. They had to isolate the classroom behind a bridge to allow me to do that. That was 24 years ago and I guarantee there are two people who who still hold that against me even though none of us work there anymore. ### Why Ethernet won Ethernet was junk if you went with the cheapest options all around, but you could make it acceptable if you invested some of the savings in improved technology. Replacing hubs with switches mostly eliminated the collision problem. Buying higher quality cards cut down on the reliability problem. But the other reason Ethernet won was because of scale. It scaled to higher speeds first, so it won the war through brute force. Ethernet made it to 100 megabits first. Anyone who saw 16 megabit Token Ring in action can tell you it was way more than 60% faster than 10 megabit Ethernet, but 16 megabit Token Ring couldn’t keep up with 100 megabit Ethernet. And when 100 megabit Token Ring came out, the next iteration was going to be 128 megabit. Gigabit Ethernet came out before 128 megabit Token Ring ever saw the light of day. And at gigabit speeds, the advantage of Token Ring over Ethernet was mostly academic. Maybe the network itself was a bit more robust in some ways, but the better efficiency didn’t matter much. The bus the cards plugged into and the disks in the system were bigger bottlenecks. In 2022, we have a faster bus and SSDs so we’d be able to tell a difference, but then we’d be back at that problem of scale. ## Telling the difference between a Token Ring and Ethernet card today Whenever a retro computing Youtuber does a mail call that includes batches of random ISA cards, inevitably, when faced with a mystery network card, they will wonder aloud into the camera whether it is Ethernet or Token Ring. Telling the difference can be difficult. Even in the ’90s when both technologies were viable, professionals sometimes made the mistake. Plugging Ethernet into a Token Ring network because they were both CAT5 is just as fun as bringing up a node at 4 megabits on a 16 megabit network. And by fun, I mean destructive. Yes, by the mid-90s, both technologies could run on RJ45 cabling. The pinout was different, but you could use the same cable for either. If you want to try to tell the difference by toning it out with a multimeter, what you need to know is that on Token Ring, the outer pins weren’t connected. On Ethernet from the same time period, the two center pins were the unconnected pins. ### The D-sub connectors But it’s usually easier to distinguish the two by looking at the other connectors. Ethernet used a 15-pin connector that looks quite a bit like a PC joystick connector. Token Ring used a 9-pin connector that looks like a 9-pin video connector or an Atari style joystick plug. ### Coax connections Coax connectors for Token Ring did exist, but were more common on Ethernet networks. The presence of a coax connector on a card isn’t a reliable indicator of either network type. But it was more common with Ethernet than Token Ring, so if I see a coax connector on an unknown card, it tilts it in favor of Ethernet. ### Speed indicators The LEDs and other printing on the card can be a very good indicator. The majority of ISA Ethernet cards you will find ran at 10 megabits. PCI cards ran at 10 and 100 megabits. So look for any speed indicator legends that might be printed or embossed on the card, either on the backplate or on the PCB itself. Token Ring ran at 4 megabits and 16 megabits. So on an ISA card, if you see both a link activity light and a speed light, and the light indicates a speed of 4 or 16, that’s Token Ring. If there is a dip switch to set a speed of 4 or 16 megabits, that’s Token Ring. ### Brand You can’t necessarily go by brand. IBM sold Ethernet cards, and Intel and 3Com did make Token Ring cards. So don’t automatically assume a 3Com or Intel ISA card that looks like a network card is Ethernet. There were other obscure makers of Token Ring cards, including Thomas Conrad and Madge. ## Is Token Ring hardware worth messing with today? I liked Token Ring when it was still on the market, though I might have thought differently if I had been in on the yearly computing budget. But once it was becoming clear that Token Ring was the Betamax of networking, people started replacing it with Ethernet. Since the cards took up less space, they were less likely to get scrapped than the equipment in the racks or wiring closets. It’s easier to find the cards today than the necessary supporting infrastructure, like a MAU, the equivalent of an Ethernet switch. And bridging Ethernet and Token Ring is more difficult than just slapping one of each card in a Linux box and configuring the two cards to route. That’s not to say using it is impossible today. It’s impractical and difficult. But if that’s your idea of fun, don’t let me dissuade you. It’s not my idea of fun. But I don’t think coax-based Ethernet is worth messing with either, and there are people who do that. ## Why anyone messed with Token Ring at all One question I hear sometimes is why anyone messed with Token Ring at all, since Ethernet was an open standard, and open standards are better. It helps to remember that the IBM of the 1980s was not the same company that IBM is today. Not only you were they a dominant player in the personal computer market, they were also the dominant player in the minicomputer and mainframe markets, which, at the time, was what some people considered serious computing. It was the preferred networking option for IBM minicomputers and mainframes. There was a saying in the 1980s that nobody got fired for choosing IBM. That alone gave Token Ring a chance, for a few years. ARCNET was another competitor from the same timeframe. It, too, was a contender for a while because it was backed by Datapoint, a pioneer in office automation using small computers. ## Are Ethernet and Token Ring interchangeable or interoperable? Sometimes you will see cards and hubs listed on eBay as both, which may lead someone to believe the two are interchangeable, or that some kind of dual-standard cards and hubs existed for a time. Don’t believe the listing. Network cards were one or the other, not both. Hubs and switches are Ethernet. The equivalent equipment for Token Ring was called a MAU. Unless you can tell from looking at the photos what it is, don’t buy it. And if they listed it as both, assume it’s untested. If the price is good and the photographs permit identification, you _may_ be able to snag a bargain.

What Happened to the Desktop Metaphor?
For a long time, personal computers tried very hard to explain themselves. You had a desktop. On that desktop were files and folders. Programs opened in windows. Commands were grouped into menus. If you wanted to move something, you dragged it somewhere else. If you wanted to throw it away, there was usually a trash can or recycle bin waiting for it. None of that was accidental. Early graphical interfaces borrowed heavily from the physical office because computers were unfamiliar and needed a way to make abstract operations understandable. A folder on a screen was not really a folder, of course, but the metaphor gave users a mental model for what the computer was doing. That model was never perfect, but it was remarkably successful. What interests me now is how much of it modern software has gradually hidden. ## The Desktop Was an Explanation The traditional desktop interface exposed a great deal of the computer’s structure. Files existed in particular places. Folders contained other folders. Applications were separate things that you launched. A window usually belonged to a particular program, and menu bars showed you what commands were available. Even if you did not understand the technical details underneath, the interface gave you a reasonably coherent picture. You could learn where things were. That mattered more than it might appear. Once someone understood the basic hierarchy of drives, directories, folders, and files, that knowledge transferred from one program to another. Saving a document in a word processor was conceptually related to moving a photograph or copying a spreadsheet. The details differed, but the structure remained familiar. The desktop metaphor taught users enough about the machine to navigate it. ## The Metaphor Was Always Artificial It is easy to get nostalgic about files and folders, but the old desktop was not some pure or natural way to use a computer. It was an abstraction built on top of a much more complicated system. A directory is not literally a manila folder. A file is not a sheet of paper. A desktop on a computer can contain thousands of items in ways that would make a real desk unusable. Software designers stretched and broke the metaphor whenever it was convenient. The traditional desktop also had plenty of weaknesses. Users lost files because they forgot where they saved them. Deep folder hierarchies became difficult to manage. Applications created their own strange directory structures. Different programs used inconsistent menus and terminology. Search improved partly because browsing through directories was not always the best way to find information. Cloud synchronization became popular partly because manually moving files among several computers was inconvenient. Mobile interfaces changed things because a desktop metaphor designed around a large monitor, keyboard, and mouse did not translate cleanly to a small touchscreen. The old model was useful, but it was never perfect. ## Applications Started Hiding the Files One of the biggest changes has been the gradual separation between users and the files they create. On a traditional desktop system, creating a document usually involved choosing a filename and deciding where to put it. The user participated directly in organizing the information. Many modern applications do something different. You create a note, photograph, document, project, or message inside the application, and the application decides where the underlying data lives. It may be stored in a database, a private application directory, a cloud service, or some combination of the three. From the user’s perspective, there may be no file at all. There is simply “my note” or “my document” inside a particular application. That can be convenient. Most people do not want to spend their time thinking about file paths, storage formats, or synchronization directories. An application can take care of all of that and present the user with the thing they actually care about. The tradeoff is that the application becomes the map. ## Search Replaced Navigation Another change is the move from knowing where something is to asking the computer to find it. Older desktop systems encouraged hierarchical organization. If you wanted a document, you navigated through something like `Documents > Work > Projects > 2026 > Reports`. Modern interfaces increasingly assume that searching is easier. Instead of remembering the path, you type a few words into a search box and let the system locate what you need. In many cases, that is genuinely better. I use search constantly, and I would not want to give it up. Large collections of email, documents, photographs, and notes are difficult to manage using folder hierarchies alone. But search changes the relationship between the user and the information. A folder hierarchy gives you a visible structure. Search gives you results. Those are not quite the same thing. When search works well, the difference barely matters. When it fails, or when you cannot remember enough about what you are looking for to formulate the right query, the underlying organization suddenly becomes important again. ## Menus Became Buttons, Then Icons Menus have gone through a similar change. Traditional desktop applications often had a visible menu bar containing categories such as File, Edit, View, Tools, and Help. The menus were sometimes cluttered, and poorly designed applications could produce absurdly long lists of commands. Still, they served an important purpose: they exposed what the software could do. A user could explore. Modern interfaces often prefer simplified toolbars, unlabeled icons, context-sensitive controls, hidden panels, and menus tucked behind symbols such as three dots or three horizontal lines. The theory is understandable. Screens are cleaner, touch interfaces have limited space, and showing every command all the time can overwhelm users. The cost is discoverability. A menu saying “Export” tells me that exporting exists. An icon that changes depending on what I have selected may be elegant once I understand it, but it does not necessarily teach me anything. When controls are hidden until the system thinks they are relevant, users have fewer opportunities to discover capabilities by looking around. Software becomes easier to approach at first, but sometimes harder to learn deeply. ## Windows Stopped Being the Center of the Interface The window itself has changed too. Traditional desktop operating systems were built around the idea that multiple applications could be visible at once. Windows overlapped, resized, minimized, and moved around a larger workspace. The user managed the arrangement. Mobile operating systems largely abandoned that model. Applications generally occupy the entire screen, and switching between them becomes an operating-system function rather than a spatial one. That makes sense on a phone. There is not much value in putting six tiny overlapping windows on a five- or six-inch display. What is more interesting is how some of that design thinking has moved back onto desktop systems. Full-screen applications, simplified interfaces, web applications, hidden chrome, and single-purpose views are now common even on large displays. The computer is increasingly treated less like a workspace containing several visible objects and more like a sequence of activities. You are not necessarily looking at files and applications anymore. You are “checking mail,” “editing a document,” “viewing photos,” or “working in Slack.” ## The Web Changed Expectations The web probably deserves some of the credit or blame for this shift. A website does not normally expose its internal file structure to the visitor. Users do not navigate through the server’s directories looking for pages. They follow links, use menus, search, or interact with whatever interface the site provides. As more software moved into the browser, that model became normal. A web application often presents information as records, projects, conversations, cards, posts, dashboards, or workspaces. The underlying storage is intentionally invisible because there is no reason for most users to care whether a particular item lives in a database table, object store, or file. Cloud applications extended the idea further. A document can simply exist “in Google Docs” or “in Microsoft 365” without the user thinking much about what machine actually holds it. From a usability standpoint, this can be a major improvement. From the standpoint of understanding and controlling your own data, it is more complicated. ## Hiding Structure Has Benefits There are good reasons interfaces have moved in this direction. Computers have become far more complicated, and many users have no interest in learning the machinery underneath. A phone that requires someone to understand directories, processes, mount points, and file permissions before taking a picture would not be a triumph of user empowerment. Abstraction is one of the things computers are supposed to do. A well-designed application should remove unnecessary work. Automatic saving is usually better than losing an hour of writing because someone forgot to press Save. Synchronizing a document automatically across several devices is useful. Searching thousands of photographs by date, location, or subject can be far more practical than manually maintaining hundreds of directories. I am not interested in making computers deliberately harder to use just so users are forced to understand them. The problem appears when abstraction turns into concealment. ## When the Structure Disappears Completely There is a difference between not requiring users to manage something and preventing them from seeing or controlling it at all. If an application stores my information internally but also lets me export it in a useful format, that is one thing. If the only practical way to reach that information is through the application itself, the situation is different. The same applies to synchronization. Hiding the mechanics of syncing files is convenient. Making it impossible to determine whether a file is actually local, remote, cached, or available offline can become a problem. Modern systems sometimes blur those distinctions so thoroughly that even experienced users have to stop and figure out where something really is. Is the document on the computer? Is it in the cloud? Is there a local copy? If I delete it here, does it disappear everywhere? If I cancel the service, what remains? Those are questions the traditional desktop generally made easier to answer because storage was more visible. ## Understanding Structure Is Still Useful One consequence of hiding structure is that users may become very good at particular applications without developing a broader model of how computers organize information. That is not necessarily their fault. The software has stopped teaching them. If an application handles filenames, locations, extensions, synchronization, and storage automatically, there is little reason for a new user to learn those concepts until something goes wrong. Then they become important very quickly. Anyone who has provided technical support has probably encountered variations of the same problem: someone knows a document exists but has no idea where it is. It may be in Downloads, Documents, a browser’s temporary storage, OneDrive, Google Drive, an email attachment, or an application’s private storage. The computer has made the structure invisible right up until the moment the user needs to understand it. ## The Desktop Is Not Dead Despite all this, the desktop metaphor has not disappeared. Windows, macOS, Linux desktops, and traditional file managers still use files, folders, windows, and hierarchical storage. Professional work in programming, media production, system administration, research, and many other areas still depends heavily on visible files and directories. Even newer interfaces frequently fall back on desktop concepts when users need more control. Export a project, upload an attachment, choose a backup location, organize source code, or manage photographs outside an application, and files and folders quickly return. The metaphor survives because the underlying concepts remain useful. What has changed is that they are no longer the first thing many users see. ## We Gained Convenience and Lost Some Legibility I do not think the answer is to return every computer to the interface conventions of 1995. Modern interfaces have solved real problems, and many of the changes that weakened the traditional desktop metaphor also made computers easier to use. Still, I think something was lost when software stopped showing as much of its structure. Files and folders gave users a mental map. Menus exposed capabilities. Windows made applications visible as separate things sharing a workspace. None of those ideas perfectly represented what the computer was actually doing, but they made important parts of the system understandable. Modern interfaces often provide more convenience while asking users to understand less. Most of the time, that works because the software handles the hidden details successfully. The trouble begins when it does not. A good abstraction should save us from unnecessary complexity without making the underlying system incomprehensible. The desktop metaphor was clumsy in places, but one of its strengths was that it gave users enough of the structure to make sense of their own computers. I am not convinced that hiding more of that structure is always progress.

Mit 21 habe ich Webse en weiteren Unternehmen habe ich Back up now beitet und mich auf Konzeption, Skalierung und technische Machbarkeit von Geschäftsmodellen fokussiert.

In den letzten Wochen habe ich mir bewusst viel Zeit genommen, mich tiefergehend mit ChatGPT Codex und Claude Code auseinanderzusetzen. Mit Codex habe ich ein Plugin für mein Smart-Home-System gebaut, um mein Energiemanagement (HEMS) an unsere Anforderungen anzupassen.

Die Software basiert ausschließlich auf Open Source: Python, PostgreSQL und Flutter für das Frontend. Das Plugin liest via Modbus TCP den Wechselrichter aus, verbindet sich mit der Wallbox, der Batterie, mit Solcast für die PV-Prognose und meinen direkt ansteuerbaren Verbrauchern.

Vierzehn Stunden Entwicklung, fünf Stunden Testing, dann eine Woche Optimierung und Bugfixing - und nun automatisiert mein individuelles HEMS alles eigenständig.

Früher wurden dafür hohe fünfstellige Beträge ausgegeben. Jetzt ist es einen Prompt entfernt. Individualentwicklung boomt und die Möglichkeiten wirken grenzenlos.

Was mich daran am meisten beschäftigt, ist nicht die Technik. Es ist die Tatsache, dass Softwareentwicklung viel dynamischer wird und einem breiteren Publikum zugänglich wird.

Natürlich bedeutet das (noch) nicht, dass sichere und performante Software einen Prompt entfernt ist. Aber man benötigt keine hohe Vorstellungskraft, um zu sehen, dass KI sehr bald bei Security- und Architekturfragen vollautomatisch leistungsfähige Systeme konzeptioniert und baut.

Die Frage ist somit nicht mehr, ob man etwas bauen kann. Die Frage ist, ob es jemand benötigt und man einen Bedarf decken kann.

Eines ist aber klar: Menschen mit viel Kreativität haben nun ein Tool an der Hand, das ihnen dabei hilft, technische Hürden schneller zu überwinden.

I was awful at bike maintenance. But OS maintenance doesn't even need oil. Update every godsdamn day, before you start work. Reboot if needed. Learn to save your work. This simple "life hack" prevents 99% of update-related annoyances with software.

The Dock on Mac, From OS 10 to macOS 27
I wrote the chapter on app icon history for _The iOS App Icon Book_. The other day I found an old note stashed away where I had started researching the macOS version of that chapter (which Michael ultimately ended up writing). At the time, I didn’t know what to write. I mean, how do you write a history of icon design for the Mac? It’s rich! To get my creative juices flowing, I started by researching the different docks in macOS through the years and compiled them all into a single graphic (big shout out to this compilation of images on 512 Pixels). I just wanted to preserve and archive that image. Check out the high-res version here. That’s it, that’s the post.

The holy quinity of UNIX workstations
Many of us are interested in retrocomputing. There’s such a rich history of eras and machines to choose from, and countless niches and nuances to get lost in. Some people make it easy for themselves and are into old computers that are readily available at low prices, like the Commodore 64 or mid-’90s Macs, while others make it a bit harder on themselves by focusing on, say, computers from the former Soviet Union or NEC machines from Japan, which are harder to find and probably require a bigger purse, too. And then there’s people like me. I’m making things incredibly hard on myself, because I am obsessed with a very specific set of computers – just five machines, to be exact. “Surely,” I hear you think, “collecting a mere five specific machines can’t be that hard, no? That’s how many spare Pismos I have in a box in case my primary one needs spare parts!” Sadly for me, the five computers I want to own more than any other are not particularly easy to find, and even when you do find one of them, pricing can easily reach the level of a decent used car. Regular OSNews readers will know: I am infatuated with UNIX workstations, or more specifically, UNIX workstations of the early 2000, and even more specifically, the final five models built by the last commercial UNIX vendors. So far, I’ve managed to get my hands on a mere two of them, but before my time on this earth come to an end, I intend to complete my Holy Quinity of UNIX Workstations. Let’s go down the list, roughly ordered by attainability. HP c8000: PA-RISC/HP-UX The HP c8000 is the absolute pinnacle of HP’s long-running line of workstations based on the PA-RISC architecture. The first PA-RISC workstation was launched in 1986, and HP would continue to improve the architecture and release new workstations all the way up until 2004, when the c8000 would be their last model. For the c8000, HP actually went all-out: it came with two dual-core PA-RISC processors running between 900MHz and 1.1GHz (depending on configuration), a maximum of 24GB of RAM, and a variety of graphics cards to choose from. It was a veritable swan song for the architecture. HP’s commercial UNIX operating system, HP-UX, is even older than PA-RISC, with the first version being released in 1982, and its final version, HP-UX 11i v3 (or 11.31) released in 2007. This final version of HP-UX was updated and supported all the way up until 31 December 2025, but things are actually a bit more complicated than that. The last workstation release of HP-UX for PA-RISC was 11i v1 (released in 2000), while the last workstation release for Itanium workstations was 11i v2 (released in 2005). Do note that HP would provide updates, fixes, and patches to these versions long after the mentioned release dates. Speaking of Itanium, HP’s final Itanium workstation was the zx6000, released in 2002, which can pack up to two single-core 1.5Ghz Itanium 2 processors. There’s a very real case to be made that the zx6000 should also be part of this list, since it’s both a little faster than the c8000 (in its dual 1.5GHz configuration) and runs a newer version of HP-UX. However, since Itanium workstations never really had much of an impact in the market (even HP only ever released two models), and since it lacks the decades of pedigree that comes with PA-RISC, I consider them a mere curiosity. A very cool curiosity that I’d love to own, but a curiosity nonetheless. Anyway, this is one of the two machines I already own. I have a new-in-box (when I bought it a few years ago) HP c8000 with two dual-core 1.0Ghz PA-RISC processors, 8 GB of RAM, and an ATI FireGL X3 AGP graphics card with 256 MB, the fastest the c8000 will take. It’s also got two SCSCI 74 GB hard drives in a striped RAID for better performance, and I added an LTO 4 tape drive so I could create bootable backups that will restore the machine if anything ever goes wrong. It’s running HP-UX 11i v1, with as many of the updates, patches, and fixes I could find – which is one of the major roadblocks for anyone trying to get into HP-UX. Installation media are relatively easy to come by if you know where to look (assuming you know which specific version you need), but any updates, patches, and fixes from roughly later than 2005 are almost impossible to find. Some can be discovered through My HPE Software Center, if you have the patience of an angel and the perseverance of a honey badger (it’s a really terrible website), but most things are all locked away behind expensive support contracts or just gone entirely. I’ve contacted HPE several times in several different ways about the preservation of HP-UX, but they never replied – clearly, they just don’t care about the preservation of their legendary UNIX platform or the enthusiast community buying PA-RISC hardware on eBay for personal use and experimentation. Sad, but par for the course. The c8000 is quite easy to find on eBay, but do be aware that the “cheap” offerings of around €800 are the versions with just one processor. To get the version with two processors, expect to shell out twice as much. Spare parts and upgrades are readily available, too. Sun Ultra 45: SPARC/Solaris The Sun Ultra 45 needs no introduction here on OSNews, as I published an in-depth article about this machine and all the cool things you can do with it late last year. My Ultra 45 was an incredibly generous gift by Adriaan de Groot, who owned this machine as part of his work on porting KDE to Solaris way back in the day. I then ordered various upgrades to the machine to max it out with two UltraSPARC IIIi processors running at 1.6GHz, 8 GB of RAM, and the Sun XVR-2500 with 256MB, the fastest

ET: "Aw, that's sweet dear. I see you've added yourself as the fellow with bright yellow boots and a huge dong."

JT: "Well you know I always wondered what it would be like to have yellow boots."

Note: Edith inspired the elf maid Luthien; the boots mean Tom Bombadil.
