Remembering my great-grandfather, William George Edwards who lost his life on 27th March 1915. Chief Engineer on the SS "Aguila", attacked by a U-boat. His son, my grandfather, was just 9 at the time. #lestweforget

3Dfx. Simply the best! I remember buying my first 3Dfx videocard - an Orchid Righteous 3D. Truly a game changer! Programmers could use the Glide 3D graphics API or battle with an early version of DirectX.

Apparently overclocking calculators is actually a thing!

Preparing for the Retro Computing Festival ( Gaming Edition ) 2025 at The Centre for Computing History in Cambridge next weekend. Here's a Visual Code setup that allows me to build 'Galaforce 2' from its original 6502 source code and deploy the game to an emulator on a PC. Simple, quick workflow!

The development studio for 'X2: Wolverine’s Revenge' - Bruntwood Hall, Cheadle, Manchester (2002). This is where we developed the game - on the top floor, formerly the servant's quarters. I'm at the back popping up my head to see what's going on. That arched window is where we are located - top left

Here's a Sinclair Microdrive cartridge with a UK pound coin for comparison. We trusted these mini-magnetic tape loops with our valuable data in the 1980s. Totally insane! To be fair, they were actually quite reliable. The tape loop is 5 metres long and stores a minimum of 85 to 100KBytes of data.

VCR tape copying virus! Hilarious. I should have implemented a similar thing in my BBC Micro game protection systems.

In Blake 7, the flight computer of the Scorpio was in fact powered by an Acorn System 1. 6502 rules the universe!
Have you ever wondered what the flight computer of the Scorpio was in #Blake7?
Professor Steve Furber lets us in on a little secret.

Picked up my Sinclair Oxford 300 from the calculator doctor @breakintoprogram.co.uk . Dean was able to track down the fault and get it back up and running again. We also had time to have a catch-up and talk about the good old days. Many thanks, Dean!
Good chat with my good friend @kevedwardsretro.bsky.social this morning - he came to pick up his repaired Sinclair Oxford 300 calculator and we ended up chewing the cud for a couple of hours. We used to work together years ago at Software Creations in Manchester, and have kept in touch.

Quick, recover the data before the disk totally dies! Squeaky disks always get my heart racing.

Moldy disks - my pet hate! Especially when you have important disks to try and archive. This Aculab DASH-80 system disk is probably the only one in existence. I have managed to recover most of it after a lot of cleaning. A bit more work and I can hopefully fully recover.

A signed print of the cover artwork for 'Acorn : A World in Pixels' by Ste Pickford @stepickford.bsky.social. Ste and I worked together on several games at Software Creations in the 1990s. I love this artwork. Can you identify all of the characters/games featured?

45 years ago, the arcade game PAC-MAN was launched in North America ( October 1980 ). It was an instant hit and soon became one of the most iconic videgames of all time. 100s of copy-cat versions were created for home computers, virtually all were un-licensed. One of my all-time favourite games.

I almost missed this anniversary! LEGO DC Super-Villains was launched in North America on the 16th October, 2018 - other regions shortly after. A great game and an amazing development team! I chose The Joker variation of the 'developer brick' for this game.

Way back in 1998 I was working on my first PC title, 'Incoming'. I was tasked with CPU & GPU optimizations and 3D card compatibility. Back then PC 3D cards were in their infancy and had lots of issues, mostly associated with their drivers. Sometimes we had to work around know problems with hacks!

Here's the letter I received from Superior Software after sending them an early version of BBC Micro 'Crazee Rider'. I'd only been working on the game for a short time so we were still working out which direction we should take. The original brief was a follow up to 'Overdrive', but with corners.

The Acorn Springboard, an ARM co-processor upgrade for the IBM PC in the form of an ISA card. I don't think many of these were actually produced and are certainly rarer than the ARM Evaluation System Second Processors which attach to a BBC Micro. Does anyone have one of these or ever used one?

The news section of Electron User kindly gave me some free publicity for Galaforce when it was launched. I think this was in the October 1986 issue.

Just got off a zoom call with an old friend from the Software Creations & Genepool days. Craig Houston and I worked on NES Wolverine, SNES Spider-Man / X-Men: Arcade's Revenge and X-2 Wolverine's Revenge. Great to have another catch-up. Photo shows me in blue jumper and Craig right at the back.
