Microsoft Updates MS-DOS GitHub Repo To 4.0

April 26, 2024 by Tom Nardi 24 Comments

We’re not 100% sure which phase of Microsoft’s “Embrace, Extend, and Extinguish” gameplan this represents, but just yesterday the Redmond software giant decided to grace us with the source code for MS-DOS v4.0.

To be clear, the GitHub repository itself has been around for several years, and previously contained the source and binaries for MS-DOS v1.25 and v2.0 under the MIT license. This latest update adds the source code for v4.0 (no binaries this time), which originally hit the market back in 1988. We can’t help but notice that DOS v3.0 didn’t get invited to the party — perhaps it was decided that it wasn’t historically significant enough to include.

That said, readers with sufficiently gray beards may recall that DOS 4.0 wasn’t particularly well received back in the day. It was the sort of thing where you either stuck with something in the 3.x line if you had older hardware, or waited it out and jumped to the greatly improved v5 when it was released. Modern equivalents would probably be the response to Windows Vista, Windows 8, and maybe even Windows 11. Hey, at least Microsoft keeps some things consistent.

It’s interesting that they would preserve what’s arguably the least popular version of MS-DOS in this way, but then again there’s something to be said for having a historical record on what not to do for future generations. If you’re waiting to take a look at what was under the hood in the final MS-DOS 6.22 release, sit tight. At this rate we should be seeing it sometime in the 2030s.

Combadge Project Wants To Bring Trek Tech To Life

April 25, 2024 by Tom Nardi 12 Comments

While there’s still something undeniably cool about the flip-open communicators used in the original Star Trek, the fact is, they don’t really look all that futuristic compared to modern mobile phones. But the upgraded “combadges” used in Star Trek: The Next Generation and its various large and small screen spin-offs — now that’s a tech we’re still trying to catch up to.

As it turns out, it might not be as far away as we thought. A company called Vocera actually put out a few models of WiFi “Communication Badges” in the early 2000s that were intended for hospital use, which these days can be had on eBay for as little as $25 USD. Unfortunately, they’re basically worthless without a proprietary back-end system. Or at least, that was the case before the Combadge project got involved.

Designed for folks who really want to start each conversation with a brisk tap on the chest, the primary project of Combadge is the Spin Doctor server, which is a drop-in replacement for the original software that controlled the Vocera badges. Or at least, that’s the goal. Right now not everything is working, but it’s at the point where you can connect multiple badges to a server, assign them users, and make calls between them.

It also features some early speech recognition capabilities, with transcriptions being generated for the voices picked up on each badge. Long-term, one of the goals is to be able to plug the output of this server into your home automation system. So you could tap your chest and ask the computer to turn on the front porch light, or as the documentation hopefully prophesies, start the coffee maker.

There hasn’t been much activity on the project in the last year or so, but perhaps that’s just because the right group of ~~rabid nerds~~ dedicated developers has yet to come onboard. Maybe the Hackaday community could lend a hand? After all, we know how much you like talking to your electronics. The hardware is cheap and the source is open, what more could you ask for?

Supercon 2023: Alex Lynd Explores MCUs In Infosec

April 24, 2024 by Tom Nardi 9 Comments

The average Hackaday reader hardly needs to be reminded of the incredible potential of the modern microcontroller. While the Arduino was certainly transformative when it hit the scene, those early 8-bit MCUs were nothing compared to what’s on the market now. Multiple cores with clock speeds measured in the hundreds of megahertz, several MB of flash storage, and of course integrated WiFi capability mean today’s chips are much closer to being fully-fledged computers than their predecessors.

It’s not hard to see the impact this has had on the electronics hobby. In the early 2000s, getting your hardware project connected to the Internet was a major accomplishment that probably involved bringing some hacked home router along for the ride. But today, most would consider something like an Internet-connected remote environmental monitor to be a good starter project. Just plug in a couple I2C sensors, write a few lines of Python, and you’ve got live data pouring into a web interface that you can view on your mobile device — all for just a few bucks worth of hardware.

But just because we’re keenly aware of the benefits and capabilities of microcontrollers like the ESP32 or the Pi Pico, doesn’t mean they’ve made the same impact in other tech circles. In his talk Wireless Hacking on a $5 Budget, Alex Lynd goes over some examples of how he’s personally put these devices to work as part of his information security (infosec) research.

80s Function Generator Is Both Beauty And Beast

April 23, 2024 by Tom Nardi 11 Comments

You know how the saying goes — they don’t make them like this anymore. It’s arguably true of pretty much any electronic device given the way technology changes over time, though whether or not it’s objectively a bad thing is going to vary from case to case.

As a practical example, take a look at the insides of this 80’s vintage HP 3314A function generator shared on the EEV Blog Forum by [D Straney].

With multiple PCBs stacked on top of each other, it’s hard to imagine that more components could possibly be crammed into it. One board in particular appears to be an entire Motorola 6800 computer, something which today would likely be replaced with a single microcontroller.

Which is actually why [D Straney] shared this with us in the first place. After seeing our recent post about a modern waveform generator that’s basically an empty box thanks to its modern components, they thought this would be a nice example of the opposite extreme.

So, is it a good or a bad thing that test equipment isn’t made this way anymore? Well, it’s hard to argue with the improved capabilities, smaller footprint, and reduced cost of most modern gear. But damn is the inside of this HP 3314A gorgeous. As one of the commenters on the page put it, hardware from this era was really a work of art.

VCF East 2024 Was Bigger And Better Than Ever

April 17, 2024 by Tom Nardi 16 Comments

I knew something had changed before I even paid for my ticket to this year’s Vintage Computer Festival East at the InfoAge Science and History Museum in Wall, New Jersey.

Over the last couple of years, attendance has been growing to the point that parking in the lot directly next to the main entrance has been reserved for only the earliest of risers. That hasn’t described yours truly since the days when I still had what my wife refers to as a “real job”, so that’s meant parking in the overflow lot down the road and walking the half a mile or so back to the main gate. Penance for working on the Internet, let’s call it.

But this time, while walking along the fence that surrounds the sprawling InfoAge campus, I came across an open gate and a volunteer selling tickets. When commenting to her that this was a pleasant surprise compared to the march I’d anticipated, she responded that there had been so many people trying to get into the main entrance that morning that they decided to station her out here to handle the overflow.

I was a few steps past her table and into InfoAge before the implications of this interaction really hit me. Two entrances. How many attendees does there need to be before you setup a secondary ticket booth out by the reserve parking lot just to keep things moving smoothly? Well, I can’t tell you what the exact number is. But after spending the rest of the day walking between all the buildings it took to contain all of the exhibits, talks, and activities this year, I can tell you it’s however many people came to VCF East 2024.

Compared to its relatively humble beginnings, it’s incredible to see what this event has grown into. InfoAge was packed to the rafters, and despite what you might think about a festival celebrating decades old computing hardware, there were plenty of young faces in the crowd. I’m not sure exactly what’s changed, but the whole place was positively jumping. Perhaps it’s partially the generational nostalgia that’s kept Netflix cranking out new seasons of the 1980’s set Stranger Things. I’m sure attention (and attendance) from several well known YouTube personalities have played a big part as well.

Whatever the magic formula that’s turned what was once a somewhat somber retrospective on early desktop computers into a major destination for tech lovers, I’m all for it. Love Live the Vintage Computer Festival!

The Next Evolution Of The Raspberry Pi Recovery Kit

April 16, 2024 by Tom Nardi 22 Comments

At Hackaday, the projects we cover are generally a one-off sort of thing. Somebody makes something, they post it online, we share it with our audience — rinse and repeat. If a project really captures people’s imaginations, it might even inspire a copy or two, which is gratifying for everyone involved. But on the rarest of occasions, we run across a project like [Jay Doscher]’s Recovery Kit.

To say that the Recovery Kit was an inspiration to others would be putting it mildly. Revolutionary would be more like it, as it resulted in more “Pi-in-a-Pelican” builds than we could possibly count. So it’s only natural that [Jay] would return to the well and produce a second version of his heavy-duty cyberdeck.

PicoNtrol Brings Modern Controllers To Atari 2600

April 13, 2024 by Tom Nardi 10 Comments

While there’s an argument to be made that retro games should be experienced with whatever input device they were designed around, there’s no debating that modern game controllers are a lot more ergonomic and enjoyable to use than some of those early 8-bit entries.

Now, thanks to the PicoNtrol project from [Reogen], you can use the latest Xbox and PlayStation controllers with the Atari 2600 via Bluetooth. Looking a bit farther down the road the project is aiming to support the Nintendo Entertainment System, and there’s work being done to bring the Switch Pro Controller into the fold as well.
