The SCROLL keyword was the mainstay of 1K games on the ZX81, as it allowed full screen motion with minimal effort! #TGIF

Every American needs to watch this:

True or false: Red Dwarf's Holly once dated a ZX81.

I once again own the first computer I ever owned. Very happy to have this for the collection even though I never loved this thing. In fact, I hated it. I was so envious of my friends with Spectrums.

I'm looking for programs that need/ can use more than 16k. So far, found www.zx81stuff.org.uk/zx81/tape/Mu...

Did you have MORE than 16K for your ZX81? What did you do with it? Or was it just for bragging rights?

ZX81 owners needed a little more help

#OnThisDay 1980 : The Sinclair ZX80 was officially launched. #retrogaming #80s

Happy 46th birthday to the Sinclair ZX80! Here's my own, super clean example.

Huzzah! Any excuse to get my own out :D

That is a pretty font! Shame there is no slash through the zero though.

It is very pretty! I'm going to have a go at some binary spelunking, and see if I can get the 4K font into the 8K version of ZX80+ (the ZX Spectrum 128 based emulator I was using). If that works maybe even have a go with a normal ROM file for use in other emulators.

Il y a 46 ans, le 29 janvier 1980, fut lancé le ZX80 par la firme Sinclair Research. Ce micro-ordinateur basé sur un CPU Zilog Z80 sera le premier ordinateur vendu au Royaume Uni pour moins de cent Livres. Il s'en écoulera environ 100.000 unités #LaPetiteInfoDuJour

Dear Texas Instruments, please put the SN76489 back into production.

On Saturday's stream I switched to ZX80 for one of the type ins but quickly became stuck. Done some digging and in the 4K ROM (the one I was using) those functions dont actually exist - only in the 8K ROM.. Problem there is we lose that pretty ZX80 font 😔

New blog post: Part 3 of the new CRTC microcontroller for the Minstrel 4th. blog.tynemouthsoftware.co.uk/2026/01/a-ne... The pictures show the stages of the hardware development (so far)

I'm sitting here crying. Watching the footage and reading the accounts of what happened to Alex Pretti has broken me...

With all due respect

Great review and demo of the @futurewas8bit.bsky.social SD2BBC. I am going to claim full credit for the use of the RJ12 connector on the cable. That worked out really well, and as a bonus, the same cable can plug into a different adapter for the DE-9 userport connector on the BBC Master Compact.

Lots of scope for experimenting

Zen-like quality of Sinclair BASIC code running.

The coolness continued with the best looking computer manual ever published.

Captain Barnacles says: Always dress to match your work station.

Peak early 1980s design. Black, white, red. Modern typeface. Just cool.

Want to trade in your ZX81?

How long did you use your ZX80 or ZX81 before you got the RAM pack?

Picked this up from an amazing friend of mine at the weekend, it was her dads and he wanted it to go to someone who'd appreciate/get some use out of it! So of course here I am :D Anyone have one of these, known much about them. They're just a touch before my time, so very excited to dig in.

Kwyll, a new retro game creation tool initially targeting the Sinclair ZX Spectrum including the new The Spectrum, is now available to purchase. www.kwyll.com #spectrum #retro

There was definitely one for the Spectrum - zxnet.co.uk/spectrum/ttx... - which was pretty good, but it would have been something of a challenge to do the same on the ZX80 or 81, admittedly.
