Retro Computing

TL;DR Before the internet, Britain’s software underground ran on paper classifieds, cassette tapes, and the Royal Mail - a postal piracy economy that shaped 1980s computing culture The economics drove it: games cost £15-£40 in 1983 (roughly £60-£160 in 2026 money), while a blank cassette and a stamp cost pennies Magazine classified pages like Micro Mart were the discovery layer - the underground’s search engine The trade scaled through the Amiga era on blank floppy disks, with traders building reputations and networks that prefigured online file-sharing culture Almost nobody involved thought of it as crime; the copyright question simply was not asked, which says as much about the era as the copying itself You can’t understand the culture of 1980s computing without understanding the postal tape trade. Before the internet democratized access, there was an entire underground economy running on paper classifieds, cassette tapes, and the British Royal Mail. ...

TL;DR Crack intros on 1980s pirated games were underground art with no commercial purpose: trainer menus (cheat systems added after copy protection was removed) and scrolltexts became the visual language of the cracking scene Trainers were augmentation, not piracy itself - groups removed protection and then added menus letting players modify gameplay The aesthetic came from constraint: tiny memory budgets and raw hardware access forced a distinctive look that groups turned into territorial signatures and reputation-building Cracking groups were organised communities with roles, rivalries, and codes of craft, and their techniques leaked into legitimate software and the demoscene The scene’s legacy is the lesson that constraints breed style - the look is still copied by artists and game developers today If you loaded a pirated Commodore Amiga game in 1988, you wouldn’t just get the game. You’d get an experience. Before the title screen, before the game even loaded, you’d see a custom introduction - a piece of underground art that served no commercial purpose and had to be coded in secret. This was the cracking scene’s gift to itself. ...

TL;DR BASIC shaped how a generation thought about programming not because it was good, but because it was the only language shipped with the C64, Spectrum, BBC Micro, and Apple II - the machine booted straight into it The gateway effect was real: zero installation, instant feedback, and a language readable enough that magazine listings could be typed in and modified by children Its flaws left marks too - type coercion taught loose thinking, and GOTO-heavy structure fuelled the structured-programming backlash Platform-fragmented dialects meant BASIC skills never fully transferred, an early lesson in lock-in BASIC’s real legacy is the idea that a computer should be programmable by its owner out of the box - something modern computing has largely abandoned When you powered on a Commodore 64 in 1983, the first thing you saw was: ...

TL;DR The SID (Sound Interface Device), designed by Bob Yannes at MOS Technology in 1981, put a genuine synthesizer - oscillators, a filter, envelope generators - inside the 1982 Commodore 64 It was originally designed as a general-purpose synth-on-a-chip to rival professional instruments, not as a computer sound chip Three voices was a brutal constraint, and composers like Rob Hubbard and Martin Galway turned it into an aesthetic - fast arpeggios simulating chords became the signature C64 sound No other chip - not Atari’s TIA, not the Genesis’s Yamaha FM - achieved the SID’s cultural dominance The chip outlived its platform: SID-based music, hardware clones, and chiptune culture are still active today The Commodore 64, released in 1982, had one feature that set it apart from every other personal computer: it had a synthesizer on a chip. Not a speaker driver. Not a simple sound generator. An actual synthesizer - with oscillators, filters, envelope generators, the same components used in professional synthesizers costing thousands of dollars. ...

Before the era of always-online DRM and AI-powered anti-tamper software, the battle against software piracy was fought with cardboard, plastic, and clever manipulation of magnetic disk geometry. In the 1980s, developers faced a simple problem: floppy disks were incredibly easy to copy. Their solutions, however, were anything but simple. This was the “Copy Protection War,” an arms race between software houses and the burgeoning “cracker” scene that birthed the Demoscene and defined digital culture for a generation. ...

There is a specific sound that defines the childhood of a generation: the high-pitched screech and rhythmic thrum of a data cassette loading into an 8-bit computer. In the early 1980s, the United Kingdom underwent a transformation that was arguably more profound than the arrival of the internet a decade later. While the US was falling in love with the office-centric IBM PC and the “appliance” feel of the Apple Macintosh, the UK was building a nation of bedroom coders. ...

TL;DR The Amiga, launched in 1985 and dead by 1994, was a commercial failure - and almost every good idea in modern computing traces back to it Preemptive multitasking, graphics compositing, hardware-accelerated audio and video, plug-and-play expansion, and system-wide scripting all shipped on the Amiga while IBM PCs were still effectively 8-bit Jay Miner’s radical design used multiple custom processors, each with its own job - the same philosophy behind today’s GPUs and specialised silicon What killed it was not the technology but Commodore’s management collapse The lesson: deep architectural insight can put a machine a decade ahead, and still lose to distribution and business execution The Commodore Amiga was not the most successful computer. It was not the fastest. It was not the cheapest. It was introduced in 1985, bought by Commodore in a panic, and discontinued by 1994 as the company collapsed. By most commercial metrics, it was a failure. ...

TL;DR Compunet, started in 1982 from a flat in Islington on the Post Office’s Prestel videotex network, became one of the world’s first genuine online communities - 15 years before most people had an email address It had everything the internet later promised: real-time messaging, online games, pseudonymous identities, digital art, and a culture of people who knew they were part of something new Prestel was the world’s first public videotex system (1979), accessed by modem and paid by the minute through modified televisions and home computers By the 1990s it had vanished - Prestel shut down, servers went offline, and the community was almost erased from computing history Its story matters because it shows online culture was invented by hobbyists on the margins, not delivered by the internet’s arrival Long before Facebook, Twitter, or Reddit, there was Compunet. In 1982, in a small flat in Islington, London, two teenagers set up a computer bulletin board system on a network called Prestel. Within a few years, it had become one of the world’s first genuine online communities - thousands of people meeting in cyberspace, exchanging messages, playing games, and falling in love, all before the internet existed in public consciousness. ...

TL;DR A demo is a real-time audiovisual production built from nothing but code and mathematics - a 4-minute music video that weighs 64 kilobytes and runs on a Commodore 64 The scene evolved from the cracking scene in the early 1980s: groups added intros to cracked games, then realised the intros were the interesting part and dropped the games Size limits (4KB, 64KB) and weak hardware were the point - constraint was the art form Demoscene alumni went on to shape the games industry, graphics programming, and real-time rendering techniques still in use It remains the strongest example of a creative community that valued technical mastery as an aesthetic in itself The demoscene wasn’t about games. It wasn’t about productivity software or killer apps. It was about taking a computer that wasn’t designed for art, stripping away the operating system, and hand-crafting something beautiful in 512 bytes of RAM. ...

TL;DR 45 years separate typing BASIC on a ZX Spectrum and using Claude Code on a MacBook - the abstraction rose, but the core loop stayed the same Programming has always been: figure out what you want, type, run, fail, fix AI agents compress the feedback loop and raise the abstraction - they do not replace the act of directing the machine The tools changed from line numbers and 16KB RAM to natural language and cloud models; the discipline did not I suspect that loop will still be true in another 45 years I’m sitting at a desk with two machines. ...
