Oh this is so beautiful.
Read it on a small phone screen, zoomed in and scrolling so you can’t see the future boxes until they’re due.
Also beware that this somehow causes tiny pieces of grit to flake off the screen and get in your eyes.

I do enjoy these videos. By this point, the BBC Micro magazines were publishing games listings that were matching commercial quality, a trend that would reach it's peak by the end of the decade.

It definitely feels like the bleak mid-winter. So why not have a cosy Saturday night in? Throw another log on the fire and join some very informal and friendly chat with other RISC OS developers online.

BBC Micro Galaforce can be found in the Power Up exhibition at the Science Museum in London - and Manchester! I feel very old now knowing that my work is in museums....
Lovely to meet you, although I mistimed it at the end of the day! Here's Galaforce in the Power Up exhibition at the @sciencemuseum.org.uk
If you're ever down in London, it would be great to get a photo next to it 😃 (or it's also setup in the Manchester science museum!)

Had an absolute blast at this year's event! It's so great speaking to members of the public and discussing all things retro computing!! This year I was in the Dev's room with fellow developers who, like me, still write software for computers that are now 40+ years old!!

I've finally finished pimping my David Braben-signed BBC Micro B+, and it can now run more variants of Bell & Braben Elite than any other contemporary machine ever.
The #BBCMicro B+ is officially the Commander-in-Chief of #8bit #Elite. 🫡

Each day we'll explore a fun optimisation in C or C++; some low-level, x86 or ARM-specific, some high-level. Hope you'll join me!

A creditable showing for the BBC Micro against various souped-up Apple IIs, but no Second Processor versions which (by the end of 1984) included 65C02, Z-80B, 6809 and 68000 options. All would have been faster yet.
Later there'd be 65C102, 80186, 80286, 32016 and of course ARM.

Ever wanted to know how your ZX81 ranked against a CRAY supercomputer from 1984? Assuming your eyesight is good enough, now you know.
