Yes. Yes, we are allowed. Because enlisting a tool to help perform a task does not in any way relate to the claim that RISC OS is itself efficient.

RISC OS on Arm is community-driven with deep roots & real potential. We want to evolve it from historical curio to a lean, modern OS for the future. #OctopusVentures #CamInnovations #AmadeusCapital #IQCapital #InvestHeritage #ScaleUp Support @riscosopen.bsky.social www.riscosopen.org/content/docu...

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.bsky.social from your armchair. #ArmPowered Support @riscosopen.bsky.social in its mission. www.riscosopen.org/content/docu...

I would guess around Jan 1987. Paul said when he met with the Acorn Board, they had five months.

Here's why we disagree: if you want to train car mechanics, you don't start them on a Formula One car, a Tesla, or a 2025 Mercedes S Class. That would be silly and likely confusing; you start with a simpler, more fundamental example, like a 2005 Ford Fiesta. Education builds upon fundamentals.

I _will_ go on: primitive graphics operations, writing software in assembly language, language interpreters, compiled high-level languages, makefiles & build systems, the value of high quality technical documentation, the Open Source movement. All valuable things to learn and RISC OS can illustrate.

Rubbish. There are many fundamentals: hardware abstraction layers, interrupt handlers, page tables & memory maps, timers, callbacks, vectors, user interface design philosophies... I could go on. RISC OS does all of these in a well-defined and easy to understand way.

Modern platforms are indeed an essential part of learning STEM. But RISC OS isn’t just history. It’s compact, readable, well documented, and still actively maintained. This can make it valuable for learning core computer and OS concepts in a way complex, modern systems often obscure.
