Fake black eye makeup or it didn’t happen.

Sinclair BASIC is not a dating site!

A digital dark age? The people rescuing forgotten knowledge trapped on old floppy disks From lectures by Stephen Hawking to the letters of British politician Neil Kinnock – it's a race against time to save the historical treasures locked away on old floppy disks.

Very interesting read for #retrocomputing fans www.bbc.com/future/artic...

Dino Boards on Tindie Reliving the 80s thru retro computing

Nearly forgot: If you're the other side of the equator I can recommend Dean's kits: www.tindie.com/stores/dinot...

Yes - they’re great too

Small Computer Central Homebrew 8-bit retro computing

Stephen over at www.scc.me.uk has loads of kits too!

Or you could build a fully ZX81 compatible DIY kit if you still have a hankering to play 3D Monster Maze on real hardware.
www.tindie.com/products/tyn...
The kit is also available from z80kits.com so you can pick one up when you're getting your RC2014 bits.

z80kits.com Home of Z80 based retro computer kits z80kits.com is the home of Z80 based retro computer kits. Build your very own computer just as you would have done in the 1980s!

Reminder: if you miss the ZX81 and long for a DIY version to tinker with Z80 code (and CP/M - but that’s another story) you need to look up RC2014.

You don’t need to be a wizard with the soldering iron to build your own little 8-bit computer.

Fifteen year old you would be proud.

So pleased that so many things got saved from the Living Computers Museum. Will be visiting myself soon.

Peak information design.

There WAS an Adrian from a Digital Basement though.

Maybe mixing up 11 and 8? Those are PDP-8s on the right: a PDP-8m (with a 8e front panel) and another based on the Harris 6120 CPU.

All the pi-based kits are excellent of course and a must-have.

Not a single Sinclair (or even a Z80?!) to be seen. I need to fix that.

The ZX Spectrum power-on screen.

What happens next?

Learning BASIC on a Research Machines 380z.

My 1kb ZX81. The joy of a 64kb RAM pack.

Next, a ZX Spectrum and - what magic is this? Colour! The feeling of achievement after entering pages of machine code - and creating a game.

Happy days.

Yes I am also old. (And older than you my friend!)

New blog post. Something a little different, a look at the wonderful 74HC74 (and 74LS74, 74HCT74 etc.) and some of the many and varied things you can do with it.

It all started when I had this brilliant idea.......

This was one of the last in a long line of PDAs using Windows CE, before they morphed into phones.

It was peak pocket tech: it could actually play MP3s and even video.

And I write multiple games and apps for it. Loved it to pieces.

Ace forever!

Go set it free!

It. Was. Awesome.

There still hasn’t been an implementation of FORTH that’s so easy to use.

Or the offspring of a ZX80 and ZX Spectrum. Rubber keyboard, white plastic case, Z80 and a bunch of logic.

ZX80 - the genesis of Sinclair's computer series that thoroughly popularized home computers and their software in the UK 🙂

This was a year ago. This whole Lord Arse thing has been an incredible journey over the last 10 years but being a part of this was the absolute icing on the cake. If you've watched it, I hope you enjoyed it.

It became second nature after a while. Your mind thinks of the codes a shifts and the key..
^ = shift

A loop might sound like this in your head:

10 F n ^L 1 ^T 10 ^z P n ^z N n

October means scares, and this time it’s Monsters..

31 Days of Monsters - Video Game Edition

Day 1

3D Monster Maze on the ZX81 (1981)

The great granddaddy of games like Doom and survival horror games, Monster Maze sees you trying to escape from a maze whilst being chased by a huge T Rex.
