Cidco MailStation as a Z80 Development Platform (2019)

The Cidco MailStation is a series of dedicated e-mail terminals sold in the 2000s as simple, standalone devices for people to use to send and receive e-mail over dialup modem. While their POP3 e-mail functionality is of little use today, the hardware is a neat Z80 development platform that integrates a 320x128 LCD, full QWERTY keyboard, and an internal modem. After purchasing one (ok, four) on eBay some months ago, I've learned enough about the platform to write my own software that allows it t

Tandy Corporation, Part 3 Becoming IBM Compatible

This article follows Part 1 of the Tandy Corporation’s history, which covers the company’s founding and the lead up to and launch of the TRS-80, and Part 2, which covers the TRS-80 Models I, II, III, CoCo, and Pocket Computer. When the TRS-80 Model I was released in 1977, the microcomputer market was small, centered around hobbyists, and many computer owners had built their machines from off-the-shelf components and/or kits. Tandy, Apple, and Commodore completely changed the market, but even th

Corrected UTF-8 (2022)

UTF-8 is decent and all but it contains some design errors, partly because its original designers just messed up, and partly because of ISO and Unicode Consortium internal politics. We’re probably going to be using it forever so it would be good to correct these design errors before they get any more entrenched than they already have. Corrected UTF-8 is almost the same as UTF-8. We make only three changes: overlength encodings become impossible instead of just forbidden; the C1 controls and the

Mercedes-Benz electric G-Wagen review: king of the off-road

As exciting as it is to see how electric technology redefines automotive transportation, it’s just as exciting to see how it alters what we already have. In the aftermarket, EV-converted restomods are quickly becoming big business. But direct from manufacturers, there’s great potential in electrifying legacy badges by seamlessly blending old design with new technology. Case in point is the 2025 Mercedes-Benz G580 with EQ Technology, better known as the EV Geländewagen (which is German for all-t

Microsoft to cut up to 9,000 jobs as it invests in AI Microsoft has confirmed that it will lay-off as many as 9,000 workers, in the tech giant's latest wave of job cuts this year.

Bought an Ampere Altra System

In the hunt for a development machine, I got to the next phase. I did some shopping, and there it is: my own Ampere Altra-based system. Why? As you may have read in my previous post, I used several AArch64 systems for local development. And the latest one, an Apple MacBook Pro, is nice and fast but has some limits — does not support 64k page size. Which I need for my work. Let’s go cheap So I have decided to buy myself an Ampere Altra system. As cheap as possible. AArch64 server parts The

Pour one out for 400/800 FireWire? macOS 26 beta 1 drops support for both standards

If you’re still rocking a first-generation iPod or, like me, are holding on to an old FireWire external drive for dear life, this one might hit hard: the first developer beta of macOS 26 Tahoe appears to have dropped support for the FireWire 400 and 800 standards. Reddit and X users (via MacRumors) who upgraded to macOS Tahoe 26 developer beta 1 say FireWire 400 and FireWire 800 devices no longer mount, whether it’s an old iPod, a MiniDV camcorder, or that trusty LaCie drive you’ve been using f

Homegrown Closures for Uxn

Homegrown closures for uxn at least, kind of... For a week or so now, I've been writing niënor, a "lispy environment for uxn". I did not want it to become a full-blown lisp but just another way of writing uxntal. Uxntal is a bit too dense for my liking, and I prefer lisp/scheme s-expression syntax. Niënor is just a compiler and a macroexpander that takes in scheme-like code and spits out uxn roms. This article describes my homegrown method of creating lexically scoped closures in this environ

The Nintendo Switch 2 is more expensive in practically every way: pricier console, pricier games, an entire Chat button you’ll eventually have to pay to use.

This 1-800 number will generate ChatGPT images, if for some reason you need that

The discourse around artificial intelligence has all been about pursuing the bleeding edge, pushing the tech into the future as fast as possible. So maybe it should be refreshing that OpenAI's latest announcement feels almost quaintly analog. Starting today, users can tap into the company's image generation by texting 1-800-ChatGPT on WhatsApp. The post on X announcing this new option for using the ChatGPT AI chatbot specifies that the feature is "now available to everyone."

You Can Now Generate ChatGPT Images by Texting a 1-800 Number on WhatsApp

ChatGPT's image generator tool now takes requests at 1-800-CHATGPT. The feature, announced by OpenAI on Monday in a post on X, allows anyone with a WhatsApp account to text that phone number and make a request for an AI-generated image using a plain-language prompt. In a CNET test, the ChatGPT hotline was able to create an old-school corded telephone image with the ChatGPT logo on it in about two minutes. The 1-800 number also accepts ChatGPT requests that aren't for images. If you don't have

Borderlands 4 will not cost $80, despite misguided executive comments

Borderlands 4, the latest entry in Gearbox Software's popular looter shooter franchise, is available to pre-order now for $70, a good $10 less than many assumed it would cost. The game's price first came into question when its September 12 release date was announced without pre-order details, and Gearbox CEO Randy Pitchford suggested that whether the game came with a $80 price tag was out of his hands. Pitchford put his foot in his mouth in a thread on X sharing a behind-the-scenes video about

I didn’t think I needed a robot lawnmower until I tried this one

I had fairly low expectations going into reviewing the Mammotion Yuka Mini 800, mainly because my understanding of robot grass mowers was outdated. The last time I had checked, they were all too expensive for me to seriously consider getting one for my suburban backyard. I also thought that these machines required guide wires to define the areas you want mowed, something
