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 256MB, 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
