The 32bit RISC OS needs to be ported to 64bit to survive, seeks help

RISC OS, the operating system from the United Kingdom originally designed to run on Acorn Computer’s Archimedes computers – the first ARM computers – is still actively developed today. Especially since the introduction of the Raspberry Pi, new life was breathed into this ageing operating system, and it has gained quite a bit of steady momentum ever since, with tons of small updates, applications, and new hardware support, including things like support for wireless networking. This development has always been a bit piecemeal, though, and the pace has never been exceptionally fast.

Now, though, time really is ticking for RISC OS: popular RISC OS platforms like the Raspberry Pi are moving to 64bit ARM only, and this poses a big problem for RISC OS: most of it is written in pure 32bit ARM assembly. As you can imagine, the supply of capable 32bit ARM boards is going to dwindle over the coming years, which would put RISC OS right back where it was before the launch of the Raspberry Pi: floundering, relying on old hardware. This is obviously not ideal, and as such, RISC OS Open Limited wants to take a big leap to address this.

Since 2011, ROOL has successfully delivered dozens of community-funded improvements through its bounty scheme. While this model has enabled steady progress, it is not suited to the scale of work now required to modernise RISC OS. The Moonshots initiative represents a fundamental shift: focused, multi-year development projects undertaken by full-time engineers.

The first Moonshot aims to make the RISC OS source code portable and compatible with 64-bit Arm platforms, a prerequisite for future hardware support. ROOL has already scoped the work, identified key milestones, and built cost models based on realistic employment and project management needs.

They’re going to need a dedicated team of several developers working over the course of several years to port RISC OS to 64bit ARM. That’s going to require quite a bit of money, manpower, and expertise, and considering ROOL has only collected about £100000 worth of donations over the past 14 years, I can see why they’re aiming to go big for this effort. All these giant technology corporations with trillion dollar stock valuations are currently relying on ARM technology, so you’d think they could empty a few socks and cough up a few million to get this effort funded properly, but alas, we all know that’s not going to happen.

I hope ROOL can make this work. RISC OS is a ton of fun to use, and occupies a unique place in computing history. I would be incredibly sad to see technological progress leave it behind, when what amount to chump change for so many wealthy companies and individuals could save it.
