A box that connected a computer to the internet over the phone line, announcing itself with a famous screech. 56 kilobits per second was the top speed, and you rarely got it.
Why it mattered
One photo could take minutes to download, and someone picking up the phone at 99% killed the whole thing. Every 90s teenager negotiated with their parents for exclusive use of the landline.

Alan Sugar's all-in-one word processor with a green screen and its own printer, sold for about the price of a typewriter. It used unusual 3-inch disks while the rest of the world went for 3.5-inch.
Why it mattered
It put a word processor in thousands of offices and spare bedrooms that would never have bought a “computer”. The odd disks became a running joke, and they still make collectors wince.

IBM's midrange business computer, the workhorse of warehouses, factories and banks. It still runs today under the name IBM i.
Why it mattered
It’s where my career in data really began, at twenty, in a warehouse with the plan upside down. The AS/400 knew where every part was meant to be. My job was knowing where they actually were.

Acorn's sturdy cream computer, built for the BBC's Computer Literacy Project. It was in nearly every British school.
Why it mattered
If you learned to program at school in the 80s, you probably did it on one of these. Elite was born on it. Acorn’s engineers later designed the ARM chip, which now runs almost every phone on the planet, so that classroom computer has a very long shadow.

Before disks, games came on audio cassettes. You pressed PLAY on a tape recorder and listened to five minutes of screeching while coloured stripes flickered round the screen.
Why it mattered
Loading a game was an act of faith. Anyone walking past, a slightly wrong volume setting or simply existing too near the tape could produce the dreaded “R Tape loading error” at 99%, and you started again. It taught a generation patience, or at least taught us to stare at stripes.

A budget Commodore machine with 16K of memory, meant as a cheaper little brother to the Commodore 64. It couldn't run C64 games, and it ended up sold off cheaply in Britain.
Why it mattered
This was my computer. While my friends were flying round the galaxy in Elite, I was learning that my machine couldn’t load their tapes and that BASIC came in different dialects. Its manual later had a second career propping up an overheating laptop.

Commodore's 64K home computer, famous for its SID sound chip. It's still listed as the best-selling single computer model of all time.
Why it mattered
In the playground there were two tribes: Spectrum owners and C64 owners, and each was sure the other had bought the wrong machine. The C64’s music was undeniably better. Spectrum owners rarely admitted this.

A home computer with custom graphics and sound chips that could do things PCs of the day could only dream of. The Amiga 500 of 1987 was the one most people owned.
Why it mattered
The Amiga made computers feel creative. It drew, it sang, it multitasked, and for a while it was simply the coolest machine you could own. Its bouncing ball demo is one of computing’s great legends.

One of the first big online services, offering email, forums and files to dial-up subscribers before the web took off.
Why it mattered
For many people this was the internet before the internet: a walled garden you dialled into, paying by the minute.

International Computers Limited, Britain's own computer giant, which built mainframes for government and big business. Fujitsu later took it over.
Why it mattered
It’s where I did my school work experience in London, the only pupil from my school sent there, without really knowing what the company did. There was no internet to look it up.

Pages of program code printed in computer magazines for readers to type in by hand, line by line.
Why it mattered
This is how many of us learned to program, mostly by learning to find our own typing mistakes. One wrong character on page four meant the game wouldn’t run, and you had no idea where to look. I was convinced I needed to become a fast typist.

Zilog's 8-bit processor, the brain inside the ZX Spectrum, the Amstrad CPC and countless other machines.
Why it mattered
Its instruction set is what you learn when you want to emulate a Spectrum. To run Daley Thompson in SQL Server I had to teach a database to pretend to be one, one instruction at a time.

Sinclair's answer to the floppy disk: tiny cartridges holding a loop of tape, about 85K each, plugged into the Spectrum through an add-on called Interface 1.
Why it mattered
They were rare, fiddly and much faster than cassettes, and they didn’t carry the copy protection that tapes did. That’s exactly why my Daley Thompson’s Decathlon in SQL Server loads from one.

Sir Clive Sinclair's little black computer with rubber keys and a rainbow stripe across one corner. It cost £125 for the 16K model and £175 for the 48K, plugged into the family telly and loaded its games from cassette tapes.
Why it mattered
For a generation of British kids this was the first computer in the house, and the reason so many of us ended up working with them. It had eight colours, one beeping speaker and a memory smaller than this paragraph’s web page, and it still felt like the future. I eventually built one inside SQL Server, so it’s fair to say it never quite left me.
