Running Windows 98 On The IPAQ IA-2 Internet Appliance

March 18, 2026 by 10 Comments

Devices that were limited to only run a web browser were relatively common around 2000, as many people wanted to surf the Information Super Highway, but didn’t quite want to get a regular PC — being in many ways the retro equivalent of a Chromebook. The Compaq iPAQ IA-2 from 2000 that [Dave Luna] got is no exception, with a Microsoft CE-based OS that is meant to be used with Microsoft Network (MSN) dial-up, which amusingly is still available today.

In order to get a more useful OS on it, like Windows 98, you have to jump through quite a few hoops, as [Dave] found out. Although there is an IDE connection on the mainboard, this cannot be booted from, likely due to BIOS limitations. This means that he had to chain boot via the 16 MB NAND Flash drive that the original OS booted from, which was done by writing MS-DOS to the Flash drive using another workaround as it’s not a standard IDE device either.

From this you can then boot Windows 98 from an IDE drive by pretending that it’s an ATAPI IDE device to dodge a limitation on IDE devices. The system’s hardware isn’t really going to make it into a blazing fast retro computer. It only has a 266 MHz Geode GX1 CPU and supports up to 256 MB of SDRAM. The IA-2 is also limited to 800×600, which required the use of an external monitor (as seen above) hooked up to the internal VGA port to set the proper resolution in the OS.

But at least it can run DOOM, so that bare minimum requirement can be ticked off.

Repurposing Old AMD APUs For AI Work

March 18, 2026 by 21 Comments

The BC250 is what AMD calls an APU, or Accelerated Processing Unit. It combines a GPU and CPU into a single unit, and was originally built to serve as the heart of certain Samsung rack mount servers. If you know where to find cheap surplus units of the BC250, you can put them to good use for AI work, as [akandr] demonstrates.

The first thing you’ll have to figure out is how to take an individual BC250 APU and get it up and running. It’s effectively a full system-on-chip, combining a Zen 2 CPU with a Cyan Skillfish RDNA 1.5 GPU. However, it was originally intended to run inside a rackmount server unit rather than a standalone machine. To get it going, you’ll need to hook it up with power and some kind of cooling solution.

From there, it’s a matter of software. [akandr] explains how to get AI workflows running on the BC250 using Ollama and Vulkan, while noting useful hacks to improve performance like disabling the GUI and tweaking the CPU governor. The hardware can be used with a wide range of different models depending on what you’re trying to achieve, it just takes some careful management of the APU’s resources to get the most out of it. Thankfully, that’s all in the guide on GitHub.

We’ve already seen these AMD APUs repurposed before for gaming use. Unfortunately the word is out already  about their capabilities, so prices have risen significantly in response to demand. Still, if you manage to score a BC250 and do something cool with it yourself, be sure to let us know on the tipsline!

Hackaday Europe Tickets On Sale Now, CFP Extended

March 18, 2026 by 8 Comments

Hackaday Europe is approaching, and we’re putting tickets on sale now. “But wait, you haven’t selected the talks yet!” we hear you saying. Indeed! And that’s why we discount the first round of entries for our True Believers™ – the hard core who know that it’s going to be a fantastic event and turn up regardless. So if you want to come to Hackaday Europe on the cheap, go snap up your ticket before they’re gone.

Call for Participation Extended

Of course, giving a talk is always the best way to attend a hacker gathering like this. And we know that we said that today was the deadline for talk submissions. But we also know that many of you have advanced degrees in procrastineering, so we’re giving you a week’s extension.

Selected speakers get in free, and we’ll reserve you an early-bird ticket for putting together a legit talk proposal either way. So if you’re a first-time presenter or a wizened pro, and you have something that you’d like to say to an audience of like-minded hackers, we’d all like to hear from you. We won’t extend the deadline twice, though, so get your proposal in before March 25.

(A few people have reached out to us, wanting to avoid the Google login that the above form requires. If you’re in the same camp, write to us directly and let us know!)

Hackaday Europe

In case you don’t know, Hackaday Europe started out as a bi-annual event that we first held a decade ago in Belgrade. It has been such a success that we’re now doing it every year, and leap-frogging around Europe to spread the love. The last two three events have been in Berlin, and this is our first time in Lecco, Italy. This year, it runs the weekend of May 16th and 17th, with a pre-event on the evening of the 15th, to be announced.

What stays the same? We have a fantastic crowd who bring their passion projects with them, a fun badge to hack on, and of course food, drink, music, and merriment all along. Oh, and the talks. (You are submitting your talk, right?)

We’ll have more details coming your way in the next few weeks, so stay tuned. After March 25th, we’ll get to selecting talks, and let you all know. Get your tickets now – we can’t wait to see you all in eight-and-a-half weeks!

Forgetfulino Puts Back Up Of Source Inside The Binary

March 18, 2026 by 24 Comments

How often have you pulled out old MCU-based project that still works fine, but you have no idea where the original source code has gone? Having the binary image and the source code as separate things to keep track of usually isn’t a problem, but there’s something to be said for adding the source — and documentation — to this image if you have some flash to spare. This is basically what the Forgetfulino Arduino library by [Nader Al Khatib] does.

Essentially, the library compresses the source files and assigns it to be burned onto the flash alongside the binary. There is also a bit of code added to the firmware so that this code can be retrieved via the serial port at any time, negating the need for a firmware dump and manual disassembly. For ease of use, the library has an Arduino IDE extension that automates the process. The basic idea could also be adapted to different environments should anyone wish to take up the challenge.

You probably wouldn’t want debug builds to feature this additional payload as writing it to flash will eat up time and write cycles. But for a release build that will be put out in the (literal) field for a few years or even decades, it could be very convenient. After all, you never know when that Git repository that you relied on might go AWOL.

The Rise And Fall Of Free Dial Up Internet

March 18, 2026 by 44 Comments

In the early days of the Internet, having a high-speed IP connection in your home or even a small business was, if not impossible, certainly a rarity. Connecting to a computer in those days required you to use your phone. Early modems used acoustic couplers, but by the time most people started trying to connect, modems that plugged into your phone jack were the norm.

The problem was: whose computer did you call? There were commercial dial-up services like DIALOG that offered very expensive services, such as database searches via modem. That could be expensive. You had a fee for the phone. Then you might have a per-minute charge for the phone call, especially if the computer was in another city. Then you had to pay the service provider, which could be very expensive.

Even before the consumer Internet, this wasn’t workable. Tymnet and Telenet were two services that had the answer. They maintained banks of modems practically everywhere. You dialed a local number, which was probably a “free” call included in your monthly bill, and then used a simple command to connect to a remote computer of your choice. There were other competitors, including CompuServe, which would become a major force in the fledgling consumer market.

While some local internet service providers (ISPs) had their own modem banks, when you saw the rise of national ISPs, they were riding on one of several nationwide modem systems and paying by the minute for the privilege. Eventually, some ISPs reached the scale that made dedicated modem banks worthwhile. This made it easier to offer flat-rate pricing, and the presumed likelihood of everyone dialing in at once made it possible to oversubscribe any given number of modems.

The Cost

Once consumer services like CompuServe, The Source, and AOL started operations, the cost was less, but still not inexpensive. Some early services charged higher rates during business hours, for example. There was also the cost of a phone line, and if you didn’t want to tie up your home phone, you needed a second line dedicated to the modem. It all added up.

By the late 1990s, a dial-up provider might cost you $25 a month or less, not counting your phone line. That’s about $60 in today’s money, just for reference. But the Internet was also booming as a place to sell advertising.

CorridorKey Is What You Get When Artists Make AI Tools

March 18, 2026 by 54 Comments

You may not have noticed, but so-called “artificial intelligence” is slightly controversial in the arts world. Illustrators, graphics artists, visual effects (VFX) professionals — anybody who pushes pixels around are the sort of people you’d expect to hate and fear the machines that trained on stolen work to replace them. So, when we heard in a recent video that [Niko] of Corridor Digital had released an AI VFX tool, we were interested. What does it look like when the artist is the one coding the AI?

It looks amazing, both visually and conceptually. Conceptually, because it takes one of the most annoying parts of the VFX pipeline — cleaning up chroma key footage — and automates it so the artists in front of the screen can get to the fun parts of the job. That’s exactly what a tool should do: not do the job for them, but enable them to enjoy doing it, or do it better. It looks amazing visually, because as you can see in the embedded video, it works very, very well.
