This weekend #ProjectMerlin got support for #Linux Boot Protocol, so now it should work happly with #UBoot and things like #QEMU -kernel when LBP is enabled at build time. For now it can be tested only on the Pi 2, but as soon as I have time I'll extend it to all other platforms
@RetroTechChris I want one of these again, so I can put my Raspberry Pi in it and still run RISC OS on a piece of modern hardware:
RISC OS on Arm is community-driven with deep roots and real potential. We want to evolve it from historical curio into a lean, modern OS for the future. @OctopusVentures @cam_innovations @AmadeusCapital @iqcapital #InvestHeritage #ScaleUp Support @risc_os riscosopen.org/content/docume…
Why not run a low carbon footprint operating system called RISC OS? Just one creative example of how you can make efficiency savings for @EarthshotPrize from your armchair. #ArmPowered Support @risc_os in its mission. riscosopen.org/content/docume…
Arm's processors power billions of devices. Help us to power the preservation of RISC OS, the platform that made it all possible. Let's keep Britain's computing story alive. @Arm @renehaas237 #Legacy #Moonshots Support @risc_os in its mission. riscosopen.org/content/docume…

New blog post and a look at the first issue of Acorn Computing dated October 1992 - tantobieinternettattler.blogspot.com/2025/07/magazi…
@pikuma Archimedes! The first computer I used. Followed by a RISC PC.
Interesting 1987 issue of Popular Computing Weekly - featuring Acorns new RISC machine and Ataris souped up Mega STs, what's not to like?
Proud to wear the England shirt? Here’s another way to support British legacy: preserve our computing heritage. @EnglandFootball @FA @Lionesses #Euro2025 Support @risc_os in its mission. riscosopen.org/content/docume…
Today's fun fact: Browsing the web on an Archimedes (real hardware, not emulated) with ArcWeb is very much still possible! (Bonus hat-tip to @ActionRetro1 for creating FrogFind to make pages usable on old systems!)
Investing in British educational computing heritage means investing in our future innovators. @Raspberry_Pi #BritishTech #STEM Support @risc_os in its mission. riscosopen.org/content/docume…
The roots of British tech run deep. RISC OS on Arm powered the dreams of a generation of British techies. Help us preserve and advance this legacy. @educationgovuk #BritishTech #LegacySystems Support @riscos in its mission. riscosopen.org/content/docume…
