I find that if I’m trying to make a point with a student or a colleague about a circuit, sometimes the Falstad online simulator is worth a few thousand words. You can draw the circuit, play with the values, and even see the current flow in an intuitive way as well as make traditional measurements. […]
In 1984, William Gibson’s novel Neuromancer helped kick off the cyberpunk genre that many hackers have been delighting in ever since. Years before Tim Berners-Lee created the World Wide Web, Gibson was imagining worldwide computer networks and omnipresent artificial intelligence. One of his most famous fictional creations is the cyberdeck, a powerful mobile computer that […]
Back in the ’80s, home computers weren’t capable of much in terms of audio or multimedia as a whole. Arguably, it wasn’t until the advent of 16-bit computers such as the Amiga that musicians could make soundtrack-quality music without having to plug actual studio gear up to their machines. [Michael Wessel] is trying to bring […]
Console owners inhabit their own individual tribes depending upon their manufacturer of choice, and so often never the twain shall meet. But sometimes there are those what-if moments, could Mario have saved the princess more quickly through PlayStation buttons, or how would Sonic the Hedgehog have been with a Nintendo controller? [Danjovic] is finding the […]
The SInclair ZX 8-bit computers of the early 1980s were masterpieces of economy, getting the most out of minimal hardware. The cassette tape interface was a one-bit port, the video was (on the first two models anyway) created by the processor itself rather than a CRT controller, and the keyboard? No fancy keyboard controllers here, […]
NASA needed a small and lightweight computer to send humans on their journey to the Moon and back, but computers of the day were made out of discrete components that were heavy, large, complicated, and unreliable. None of which are good qualities for spaceflight. The agency’s decision to ultimately trust the success of the Apollo […]
We spend a lot of time in our community discussing the many home computers from the 8-bit era, while almost completely ignoring their industrial equivalents. While today a designer of a machine is more likely than not to reach for a microcontroller, four decades ago they would have used a single-board computer which might have […]
Ask a hacker to imagine computing in the 1980s, and they might think of the classic 8-bit all-in-one machines from the likes of Commodore and Atari, or perhaps the early PCs and Macs. No matter the flavor, they’ll likely have one thing in common: a lack of mobility thanks to being anchored down by a […]
[Tadao Hamada] works for Fujitsu Tokki, a subsidiary of the more famous Fujitsu. In 1956, Fujitsu decided to compete with IBM and built a relay-based computer, the FACOM128. The computer takes up 70 square meters and weighs about 3 tons. By 1959, they’d learned enough to make a FACOM128B model that was improved. [Hamada’s] job […]
The Super Nintendo recently experienced a surge in popularity, either from a combination of nostalgic 30-somethings recreating their childhoods, or because Nintendo released a “classic” version of this nearly-perfect video game system. Or a combination of both. But what made the system worthy of being remembered at all? With only 16 bits and graphics that […]
