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. 🫡

See thread for details.

This December, I'll be posting an article & video each day until Christmas in the Advent of Compiler Optimisations! #AoCO2025
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.

Ready to röck your Chuckie Eggs at @computinghistory.org.uk this weekend. That poor little Spectrum being dwarfed by the bigger machines is my original machine so be nice to it 😄

This was pretty interesting, hearing how the small team behind the 8-bit BBC Acorn computer went from specifying ULA chip designs to designing the early Arm CPU series from scratch using BBC BASIC

I'm a big fan of RPCEmu which provides an excellent RISC OS environment on my Mac when I'm travelling. In this post I'm going to explore why I have switched back to the Linux version and cover some of the issues I encountered.

This video has taken a long time for me to put together. However I think it might be the first time a Kubernetes cluster has been used to provide file/print services to a BBC micro using Econet. youtu.be/-Hs55amrFW0?...

Next week many of us will all be at CFCH in Cambridge, looking forwards to seeing lots of you there. Apparently however they are almost out of tickets, so if you don't have one yet and you fancy going it might be a good to buy one.
Oh wow, this time next we'll be in full swing! Tickets for the Saturday are close to selling out - www.computinghistory.org.uk/det/74558/Re... - alternatively, Sunday will be quieter, but still the same wonderful exhibitors - www.computinghistory.org.uk/det/74909/re... - see you all next weekend!

I will be there, with a collection of incredibly expensive 90's UNIX workstations that you were absolutely not supposed to be gaming on ... but we're going to anyway.

I've just uploaded an update to my RISC OS !RMA utility, primarily to fix RO3 compatibility (thanks to Phil Pemberton for the report) but I noticed I hadn't released the previous version that featured an important upgrade - the ability to explore ANY Heaped Dynamic Area. So, a useful update:

Here is an article with all the details about a new chunk of progresses on #UltimaVM and the new project's mascot Luma. Still lots of work to finish to get the first beta release out, but hey I am moving forward!

Given the interest Ultima has been receiving from enthusiasts and engineers, both online and at the few computer shows where I’ve demonstrated it, I think some will appreciate a more detailed look …
