Locate and eliminate the monstrous Wumpus to win fabulous prizes… well, a trophy graphic…

Review: King’s Reach — comics chieftain John Sanders’ marvellous memoir of the Ministry of Magazines

Periodical publishing is not what it was. Gone are the days when week in, week out millions of adults and kids would buy magazines or comics and spend time reading them. We will not see their like. Now it’s all about screens, not paper, and grabbing digests of information fed from social media streams. I’m not saying that’s a bad thing, just that, in the digital era, no one will ever feel the almost physical thrill of taking possession of the latest issue of a favourite title — or be eager to understand what makes the minds behind it tick.

The Sinclair ZX81: a Raspberry Pi retro restyle – Part 2

Check out my retro tech T-shirt store

Previously on ‘ZX81: a Raspberry Pi retro restyle’: I used a headerless Arduino Leonardo to connect a ZX81 microcomputer keyboard to a Raspberry Pi via USB, using code to handle normal, shifted and function-shifted key presses.

After some searching on eBay, I found an old ZX81 going cheap because it lacked cables, though when it arrived, I found the computer itself to be in excellent condition. Possibly it has never been used, though how if that were the case the cables were lost and the box got so tatty is a mystery I will probably never solve.

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

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.
