You can install RISC OS on the Pi machines. It's a British graphical operating system from 1989 which has been maintained and updated continually.

A History of ARM (part 1): Building the first chip In 1983, Acorn Computers needed a CPU. So 10 people built one. arstechnica.com/gadgets/2022/0…


Setting up an older #RISC_OS 5 system as a freebie for a returning user. It's amazing what you forget: How slow SD card storage is; How fast a Pi 3B+ was in its day; How cool it runs! It's a good little machine, but it does remind you how far we've come since then.

This is an excellent opportunity to explore professional desktop publishing on RISC OS at no cost, guided by someone with years of experience. RISC OS is open-source and can run natively on the Raspberry Pi 4, Pi 400, and earlier models. #MeetUp riscository.com/2025/ovation-p…

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

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:

A bit of a wasted afternoon, but I managed all this with two CM4001008s (and a completely unnecessary 256GB NVMe drive). #overkill #frugal #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…

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…

The Acorn A7000 was their entry level RISC PC, released in 1995, designed for the classroom.

Archimedes! The first computer I used. Followed by a RISC PC.
