Today, we’re introducing a major set of upgrades to the Framework Laptop spanning two new models – the Framework Laptop 13 (13th Gen Intel® Core™) and the Framework Laptop 13 (AMD Ryzen™ 7040 Series). We’ve not only scaled up performance and enabled an AMD-powered version for the first time, but we’ve also delivered refinements to the day-to-day user experience with a higher capacity battery, matte display, louder speakers, and more ridgid hinges. And Framework kept their promise: these new mainboards can be ordered separately and fit into the existing Framework 13″ laptop. The company also showed off their next product – a 16″ laptop that not only comes with an upgradeable GPU, but also a completely configurable input deck, so you can configure the keyboard and trackpad area in any configuration you like. I’m so happy Framework is doing well, as it shows that glued shut, non-repeairable, and non-upgradeable laptops are not some sort of universal inevitable truth.

If you’re new to the Arm ecosystem, consider this a quick primer on terms you likely have seen before but might have questions about. Well, exactly what it says.

The JH7110 isn’t amazing. But it’s not bad, either. I still wouldn’t recommend most people buy this board, unless you already know a lot about Linux and SBCs in general. That may change a year from now, but right now, this board isn’t targeted at the same market as a Raspberry Pi. At around $100, and not being quite production-ready, I’m only recommending this board to people interested in exploring RISC-V for now. This seems like an expected experience for a relatively new architecture that still has rather limited hardware and software support. When the first Raspberry Pi came out, the situation wasn’t much better either, so give it a few years and RISC-V will be in a better place in the market for sub-€100 single-board computers.

Paul Weissmann, maintainer of OpenPA, the definitive source of information on HP’s PA-RISC hardware and software, has published an article about how the state of information preservation on this topic has changed substantially since OpenPA’s founding in 1999. The main challenges for OpenPA at the time were both finding all the available information, as search engines were still young in the late 1990s, as well as making sense of it all as it was just so much and new sources kept appearing. This went on until the mid to late 2000s, when solid and stable sources could be found and referenced, which OpenPA did. The Internet and information on it changed since then, slowly but surely, in a profound way. Many original sources have disappeared and so much information has been lost in only two decades – making OpenPA the authoritative source for PA-RISC in some ways. A long journey from documenting complex information of the 1990s to an historic archive on the PA-RISC era. OpenPA is an amazing resource, so if you happen to have any information worth sharing with Weissmann, please do so.

I wrote a popular post about serial ports once, and serial ports are something I think about, worry about, and dream about with some regularity. Yet I have never really devoted that much attention to the serial port’s awkward sibling, always assuming that it was a fundamentally similar design employing either 8 data pins each way or 8 bidirectional data pins. It turns out that the truth is a lot more complicated. And it all starts with printers. You see, I have written here before that parallel ports are popular with printers because they avoid the need to buffer bits to assemble bytes, allowing the printer to operate on entire characters at a time in a fashion similar to the electromechanical Baudot teleprinters that early computer printers were based on. This isn’t wrong, it’s actually more correct than I had realized—the computer parallel port as we know it today was in fact designed entirely for printers, at least if you take the most straightforward historical lineage. Let’s start back at the beginning of the modern parallel port: the dot matrix printer. The serial port still sees tons of use today, but the parallel port seems to have vanished entirely.

This is the bigger, more deluxe of the two Mattel dedicated D&D games (the Intellivision of course had its own set, and we had a Tandyvision ourselves), the other being the DUNGEONS & DRAGONS™ Computer Fantasy Game. That was a handheld unit with a surprisingly compelling implementation of Hunt the Wumpus, and something we might talk about another time. This one is more like a board game, but with a computer antagonist and audio. The box says copyright 1980 but I think we got it late 1982 or early 1983. Either way, I was probably too young for this game at the time: it advertises 8 and up, and I would have been around six or so. It requires you to juggle a number of different audio signals and build up the maze and the objects in it (you, your competitor, the dragon, the treasure, your lifeless defiled corpses when you try to get the treasure, etc.). My recollection is that we barely played it at all. Well, better late than never. And hey: let’s find out what makes it tick. (Teaser: it’s four bits and we have an annotated die photo. Read on.) And read on you should – if you’re into amazingly detailed looks into children’s toys from the late ’70s/early ’80s based on 4 bit chips, that is. And you are, aren’t you?

On Sunday, a Chuck E. Cheese employee named Stewart Coonrod posted a TikTok video that documents the process of installing a new song-and-dance show on an old Chuck E. Cheese animatronics system—a process that involves a 3.5-inch floppy disk and two DVDs. Coonrod says it is the last update before his store undergoes a remodel that will remove the animatronics altogether. I’ve never visited this restaurant chain, but I always love peeks behind the curtain of the technology places like this use. It reminds me of our favourite bar near the red light district in Amsterdam, which used a touchscreen computer running BeOS to manage its music playlist.

So the Japanese market had very specific requirements, that PCs could not fulfill in the early DOS days. You couldn’t just replace the character ROM on your PC and make it display Japanese text (IBM did later develop the 5550 and the JX, a derivative of the PCjr, specifically for the Japanese market, and later, they developed the DOS/V variant, which added support for Japanese text to their PS/2 line, using standard VGA hardware, which by now had caught up in terms of resolution). Instead, Japanese companies jumped into the niche of developing business machines for the home market. Most notably NEC. In 1981 they introduced the PC-8800 series, an 8-bit home computer based on a Z80 CPU and BASIC. In 1982, the PC-9800 series followed, a more high-end 16-bit business-oriented personal computer based on an 8086 CPU and MS-DOS. These families of machines became known as PC-88 and PC-98 respectively (Note that the ‘PC’ name here is not a reference to IBM, as NEC had already released the PC-8000 series in 1979). I love these machines.

“Raspberry Pi boards are hard to get, probably also next year,” says Andreas Spiess, single-board enthusiast and YouTuber, in his distinctive Swiss accent. He’s not wrong. Spiess says he and his fellow Pi devotees need “a strategy to survive” without new boards, so he suggests looking in one of the least captivating, most overlooked areas of computing: used, corporate-minded thin client PCs. Spiess’ Pi replacements, suggested and refined by many of his YouTube commenters and Patreon subscribers, are Fujitsu Futros, Lenovo ThinkCentres, and other small systems (some or all of which could be semantically considered “thick clients” or simply “mini PCs,” depending on your tastes and retro-grouch sensibilities). They’re the kind of systems you can easily find used on eBay, refurbished on Amazon Renewed, or through other enterprise and IT asset disposition sources. They’re typically in good shape, given their use and environment. And compared to single-board enthusiast systems, many more are being made and replaced each year. A project I want to undertake is set up an UltraSPARC machine, and then tie several Sun Rays to them. I also want to mess around with using Linux as the host for several thin clients – they’re so cheap, and it seems like they’re really fun to mess around with.

Music Studio is a Windows-based SID music creator software. For an accurate C64 sound, it utilises the newest RESID-FP emulation available, both old (6581) and new (8580) SID chips. MS2 is capable of creating 1x speed tunes and many SID chip parameters can be edited directly using the various commands. Classic and new C64 sounds can be created with envelope parameters that can be set up in few simple steps. While I’m sure purists will greatly prefer real hardware, the cold and harsh truth is that the number of real, authentic Commodore 64 models is slowly running out, and there’s only so many Adrian Blacks in the world capable of repairing the few that can actually be repaired. Emulation – even for specific features of the C64 such as its sound capabilities – will make the C64 immortal.

The PowerStack was one of the Motorola Computer Group’s entries into the personal computer (PC) market around the time the Microsoft Windows/Intel x86 juggernaut was stumbling with their mass market Windows 3.11 replacement. It’s a compact, modular, efficient platform featuring IBM/Motorola’s PowerPC CPUs as well as best-in-class contemporary interfaces like PCI and SCSI. A compute element could be stacked with other modular I/O and storage cases to expand its capabilities without having to rehome the computer in a larger chassis. I had never heard of this machine before, illustrating just how much random non-x86 machines were produced in the ’90s. This one definitely looks more out there than most, and most likely utterly impossible to find anywhere.

Thus for many years the possibility of getting memory tagging working on these systems was an interesting possibility, but there was no idea of whether it was actually feasible or whether IBM fused off this functionality in the CPUs it sells to third parties. The POWER CPUs IBM sells to third parties are fused slightly differently to those it uses in most of its own servers, being fused for 4-way multithreading (SMT4) rather than 8-way multithreading (SMT8); it would be entirely plausible that the tagging functionality is fused off in the SMT4 parts, being that IBM i was only ever intended to run on SMT8 systems. While the ISA extension is undocumented, fairly complete knowledge about it has already been pieced together from bits and pieces, so this was not actually the major obstacle. However, there was no idea as to whether use of the memory tagging functionality might require some kind of appropriate initialization of the CPU. In theory, one need simply set a single undocumented bit (“Tags Active”) in the Power Machine State Register (MSR). However, simple attempts to enable Tags Active mode on OpenPOWER systems such as the Talos II did not succeed. This all changed when someone discovered that it was in fact possible to enable Tags Active mode on Talos II and Blackbird systems. This discovery was made by Jim Donoghue and all credit for this discovery goes to him; I publish this finding with his permission. As it turns out, memory tagging is not just limited to IBM’s own proprietary SMT8 POWER processors; it’s hiding in its SMT4 processors too. You can find these processors most notably in the systems built and sold by Raptor Computing Systems, one of which I reviewed not too long ago. Of note is that some of Raptor’s systems can now also be bought in Europe through their partner Vikings Store.

How I built the RGBeeb, a BBC Micro inside a PC case. With RGB Backlight, USB inputs, ATX PSU, and working full-height floppy drives. This project is way more involved than you think it is.

The ROMA RISC-V laptop was announced this summer with an unnamed RISC-V processor with GPU and NPU. We now know it will be the Alibaba T-Head TH1520 quad-core Xuantie C910 processor clocked at up to 2.5GHz with a 4 TOPS NPU, and support for 64-bit DDR at up 4266 MT. The TH1520 is born out of the Wujian 600 platform unveiled by Alibaba in August 2022, and is capable of running desktop-level applications such as Firefox browser and LibreOffice office suite on OpenAnolis open-source Linux-based operating system launched by Alibaba in 2020. This is a very important first step into ‘normal’ computing for RISC-V, but availability and pricing are, for now, major barriers here. I’d love to get my hands on one of these, but at these prices, that’s a massive ask.
