A popular project among Hackaday readers is to recreate a piece of home computing or gaming hardware from the past, and in that endeavour we’ve seen some truly amazing projects. Usually they take the form of bare PCBs or custom cases that look nothing like the original, but not [Cees Meijer]’s Sinclair ZX80 clone. It sports a 3D printed replica of the original computer’s vacuum-formed case, which from a distance you could be mistake for the real thing.
Internally it’s not a ZX80 at all, but a Raspberry Pi Zero running an emulator. But with a case like this one that’s not the point. It doesn’t have the full-length PCB of the original but a modern ZX80 membrane keyboard, and the Pi appears to be hiding somewhere in the “hump” used by the Astec UHF modulator on the original. There is more information in a blog post, and the model can be downloaded via Thingiverse. Handily, the files also include the original CAD file from RS DesignSpark, should you wish to modify it to your own tastes. If somebody could mate it with Tynemouth Software’s ZX80 kit then our cup would run over.
Of course, this isn’t the only retrocomputer for which a replacement case can be found.
Join us on Wednesday 29 May 2019 at noon Pacific for the Retrocomputing for the Masses Hack Chat!
Of the early crop of personal computers that made their way to market before IBM and Apple came to dominate it, few machines achieved the iconic status that the Sinclair ZX80 did.
Perhaps it was its unusual and appealing design style, or maybe it had more to do with its affordability. Regardless, [Sir Clive]’s little machine sold north of 100,000 units and earned a place in both computing history and the hearts of early adopters.
Spencer Owen is one who still holds a torch for the ZX80, so much so that in 2013, he hatched a seemingly wacky idea to make his own. A breadboard prototype of the Z80 machine slowly came to life over Christmas 2013, one thing led to another, and the “RC2014” was born.
The RC2014 proved popular enough to sell on Tindie, and Spencer is now following his dream as a retrocomputing mogul and working on RC2014 full time. He’ll be joining us to discuss the RC2014, how it came to be, and how selling computing nostalgia can be more than just a dream.
Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday May 29 at 12:00 PM Pacific time. If time zones have got you down, we have a handy time zone converter.
Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io. You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about.
What would you think if you saw a bootleg of a product you design, manufacture, and sell pop up on eBay? For those of us who don’t make our livelihood this way, we might secretly hope our blinkenlight project ends up being so awesome that clones on AliExpress or TaoBao end up selling in the thousands . But of course anyone selling electronics as their business is going to be upset and wonder how this happened? It’s easy to fall into the trap of automatically assigning blame; if the legit boards were made in China would you assume that’s where the design was snagged to produce the bootlegs? There’s a saying about assumptions that applies to this tale.
Dave Curran from Tynemouth Software had one of his products cloned, and since he has been good enough to share all the details with us we’ve been able to take a look at the evidence. Dave’s detective work is top notch. What he found was surprising, his overseas manufacturer was blameless, and the bootleg board came from an entirely different source.

At the end of the 1970s, the 8-bit home computer market had been under way for several years. Companies like Apple and Commodore had produced machines that retain a cult following to this day, and there was plenty for the computer enthusiast to get to grips with. As always though with a new technology, the trouble was that an Apple II or a Commodore Pet wasn’t cheap. If you didn’t have much cash, or you were a young person with uncomprehending or impoverished parents, they were out of reach. You could build a computer from a kit if you were brave or technically competent enough, but otherwise you were out of luck.
As you might imagine, the manufacturers understood that there was an untapped market for cheaper hardware, so as we entered the new decade a range of budget machines that appeared to satisfy that demand. Gone were internal expansion slots, dedicated monitors and mass storage, for cheap keyboards, domestic TV monitors, and home cassette recorders. 1980s teenagers would have computers of their own, their parents safe in the knowledge they were educational while the kids themselves were more interested in the games.
