@CGS2078260 The Archimedes and RISC OS should’ve been world beating. But we just let Wintel walk in and crush them.
@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:

What is currently being worked on ko-fi.com/post/WebShot-C… #RISC_OS
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…
Are you interested in coding on RISC OS? Want to learn more? Join our friendly fireside chat on Zoom—DM for credentials (unchanged). If you are a developer, come and connect. The event is this Saturday, 9th August, at 7:30 pm (GMT+1). #OpenSource #RISC_OS #Community #Code4Fun
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…
The Acorn A7000 was their entry level RISC PC, released in 1995, designed for the classroom.
