During the 80s and 90s it seemed like Japan got all the good stuff when it came to videogames. In the US there were consoles called the NES, the TurboGrafx-16, and the Genesis. While in Japan they had cooler names like: the Famicom, the PC Engine, and the Mega Drive. The latter was incorporated into a plethora of different form factors, including the little known IBM PC/Mega Drive combo known as the Sega Teradrive. Finding a rare Japanese 1990s PC stateside is a feat in and of itself, and thanks to an electronics hobbyist named [Ronnie] there is at least one Teradrive out there still running strong thanks to an upgraded CPU mod.
In theory, the Sega Teradrive was a dream-machine; combining the utility of an IBM PC with the fun of a Sega Mega Drive. The dual functionality extended to the video modes where both VGA and composite video were supported. However, the reality was that the final design was less than desirable. The Teradrive shipped in 1991 with an Intel 80286, 16-bit processor which was already two processor generations behind at the time. The meager 10Mhz clock speed was on the lower end of the performance spectrum which meant that many DOS titles ran poorly…or not at all.
Not satisfied with those specs, [Ronnie] modded his Teradrive with an adapter board containing an Intel 80486 processor clocked at 66Mhz. The upgrade, accompanied with a complete re-cap of the motherboard, brings the IBM PC to 486DX status. This opened up a few new possibilities including the Thundercats Demo in the video below:
If you were an Amiga enthusiast back in the day, the chances are you had an Amiga 500, and lusted after a 2000 or maybe later a 3000. Later still perhaps you had a 600 or a 1200, and your object of desire became the 4000. The amusingly inept Commodore marketing department repackaged what was essentially the same 68000-based Amiga at the bottom end of the range through the platform’s entire lifetime under their ownership, with a few minor hardware upgrades in the form of chipset revisions that added a relatively small number of features.
We’ve probably listed above all the various Amigas you’ll be familiar with, with a few exceptions you either didn’t have or only saw in magazines. The original A1000, the chipset-upgraded A500+, the CDTV multimedia platform, or the CD32 games console as examples. But there’s one we haven’t listed which you may never have seen unless you hail from the United Kingdom, and it’s an Amiga behind which lies a fascinating tale that has been unearthed by [RetroManCave].
In the late 1980s, Commodore sold the A500 all-in-one cased Amiga to consumers with marketing based heavily upon gaming, and the A2000 desktop Amiga to businesses with the promise of productivity software. Both machines had a 16-bit Motorola 68000 running at the same speed, with the A2000 having a lot of extra memory and a hard drive lurking within that case. The price difference between the two was inordinately high, creating a niche for an enterprising British company called Checkmate Computers to fill with their provocatively named A1500, a clever case for an A500 mainboard that gave it an expansion slot and space for that hard drive and memory.
This machine’s existence angered Commodore, to the extent that they vowed to eradicate the upstart by releasing their own UK-only A1500. The result, a comically badly concealed rebadge of an A2000 with two floppies and no hard drive, is something we remember seeing at the time, and dare we admit it, even lusting after. But the full story in the video below is well worth a watch for an engrossing insight into a little-known saga in one corner of the computing world during the 16-bt era. Towards the end it becomes a plug for the Checkmate Computers co-founder’s current Kickstarter project, but if that holds no interest for you then you are at least forewarned.
The hardware badge for the Hackaday Belgrade conference is a Retro Computer that you wear around your neck. I have one in my hands and it’s truly a work of art. It’s beautiful, it’s fun to play with, and it will be an epic platform for a glorious weekend of badge hacking! Check out the first look video, then join me below as I drill down into the details.
Get your ticket now for Hackaday Belgrade, our premier European hardware conference at the end of this month. It’s a day filled with talks, works, food, fun, and of course everyone through the door gets one of these incredible badges. The best part is the community that turns out for this event and that includes the Hacker Village that takes hold in the evening. We’ll be hacking the badges until the wee hours of the morning alongside hardware demos, presentations, lightning talks, and live IDM and DJ sets.
The Trenton Computer Festival (TCF) doesn’t have the name recognition of big technology conferences like DEF CON or HOPE. It’s not even as well known as smaller more localized conferences like DerbyCon, ShmooCon, or the Hackaday Superconference. In fact, there’s a good chance that most readers have never even heard of TCF. But despite not holding a place in the hacker lexicon, TCF has plenty to boast about. Its played host to technology luminaries from Bill Gates to Richard Stallman, and now in its 43rd year, holds the title as the longest continually running technology festival in the world.
When originally conceived in 1976, the show was devoted to the dawning age of the personal computer, but since then has evolved into a celebration of technology as a whole. When TCF kicks off on March 17th, there won’t be a media blitz or huge corporate sponsorship. There won’t be a simultaneous online stream of the event, and the only badges worn by speakers or attendees will be of the paper variety.
What you will find at TCF is a full schedule of talks given by people who are passionate about technology in its varied forms. These run the gamut from quantum computing to lock picking, from Arduino to Space Shuttle avionics.
At the heart of TCF is co-founder and current Chair Dr Allen Katz. I recently had the opportunity to speak with Dr Katz about the challenges of running a conference of this type, and the secret to keeping relevant in a wildly changing technology landscape.
When I got my first computer, a second hand 386 running MS-DOS 6.22, I didn’t have an Internet connection. But I did have QuickBASIC installed and a stack of programming magazines the local library was throwing out, so I had plenty to keep myself busy. At the time, I thought QuickBASIC was more or less indistinguishable from magic. I could write simple code and compile it into an .exe, put it on a floppy, and give it to somebody else to run on their own machine. It seemed too good to be true, how could this technology possibly be improved upon?
Of course, that was many years ago, and things are very different now. The programming languages du jour are worlds more capable than the plodding BASIC variants of the 80’s and 90’s. But still, when I found a floppy full of programs I wrote decades ago, I couldn’t help but wonder about getting them running again. With something like DOSBox I reasoned I should be able to install the QuickBASIC IDE and run them like I was back on my trusty 386.
Unfortunately, that was not to be. Maybe I’m just not well versed enough in DOSBox, but I couldn’t get the IDE to actually run any of the source code I pulled off the floppy. This was disappointing, but then it occured to me that modern BASIC interpreters are probably being developed in some corner of the Internet, and perhaps I could find a way to run my nearly 30 year old code without having to rely on 30 year old software to do it.

The 6502 has a long history with hackers. The Apple computer (the one with no keyboard or even case) had a 6502. So did the Kim-1. [Dolo’s] version is a bit more refined, though. He started it a few years ago in response to one of our contests, but he’s been making improvements to it ever since. In particular, the custom programming language, Dflat, has many improvements lately, including true functions and high-resolution drawing.
The hardware has a CPU running at over 2.5 MHz, 44K of RAM, 16K of PROM, and 16K of video RAM. There’s plenty of I/O, including a keyboard, sound, and joysticks. An SD card provides mass storage and it all goes in a hacked BBC Micro case. You can see an overview video, below.
Next weekend is the Vintage Computer Festival West, held at the Computer History Museum. Hackaday is once again proud to sponsor this event that brings together the people and hardware that drove the information revolution. [Bil Herd] and [Joshua Vasquez] will be on hand representing the Hackaday Crew.
This year’s talks show an impressive lineup of people. [Bil Herd] will be on stage with a collection of other engineers who secured Commodore’s place in history. The Computer History Museum has a very active restoration program for original computer hardware. Friend of Hackaday, [Ken Shirriff], has been working on a restoration of the Xerox Alto and is on the panel giving a talk about the process. And just to cherry-pick one more highlight, there’s a talk on system debugging before you even turn the thing on — a topic that can save you from having a very bad day with very ancient hardware.
A great part of VCF is that the exhibits are often either hands-on or demonstrations so you can actually play around with hardware which most people have never even seen in person. Add to that the collection at the Computer History Museum plus some extra exhibits they have planned for the event and you’re likely to run out of time before you make your way through everything.
Since we’ve mentioned the Computer History Museum, we also have some upcoming news. A bit later this month, Hackaday Contributor-at-Large [Voja Antonic] has been invited to visit the museum, record his oral history, and deliver to their collection an original Galaksija computer — wildly successful first as a kit and then as a manufactured computer which he built in Yugoslavia 1983. Congratualtions [Voja]!
