The Sinclair ZX81: a Raspberry Pi retro restyle – Part 1

Check out my retro tech T-shirt store

I love the design of the Sinclair ZX81. It was never a great computer, even in 1981. It only had 1KB of on-board RAM, it was slow, it was small, it could only do black and white graphics, and it’s membrane keyboard was useless for fast typing. But it looked fantastic: black, sleek and totally futuristic. Almost all other 1980s microcomputers now look very dated. No surprise there, of course, but the ZX81 still looks amazing.

Retro Review: Thorn EMI Liberator (1985)

In November 2012, I wrote and published the definitive history of the Thorn EMI Liberator, the first British laptop computer, over at The Register. I’d never even heard of the machine when I first saw a picture of it. I spotted the snap while researching the story of the Dragon 32 – some of the Dragon engineers went on to develop the Liberator after Dragon Data, by then a subsidiary of electrical industry giant GEC, was closed down.
