The day before the RISC OS North show last week, RISC OS Open Ltd (ROOL) published an announcement in the news section of their website, and emailed a press release to draw attention to it1. Titled ‘“Moonshots” initiative to Secure the Future of the OS’, the announcement outlines a significant problem that the operating system faces – one that most RISC OS users will already be well aware of: That RISC OS is 32-bit, while more and more new Arm processors are 64-bit.

Let’s talk 64-bit with Gerph – ROUGOL, 19th August

In the RISC OS world, we (should) all know that RISC OS runs on ARM processors in either 26 or 32-bit mode, depending what hardware (or emulator) you are running it on – and that we are now at the stage where 64-bit only ARM processors are becoming the norm, and RISC OS is unable to run on them.

Ask nicely, and he might show you a picture of his 43-incher! Tomorrow evening, 16th April, is when the RISC OS User Group of London next meets, and the guest speaker will be Clive Semmens, talking on the subject of his time working and playing with ARM processors. Clive’s first encounter with the processor was when he purchased an Archimedes for a classroom in Stornoway, in the Outer Hebrides, and some thirty years later he is still using them, having retired as a Senior Technical Author for ARM in 2007.…

Can I stop being so busy now, please? Pretty please? Aw, go on… Observant readers will no doubt have noticed a low post count on RISCOSitory since the Southwest Show – a grand total of eight, in fact, including the show report itself, and this year’s April Fool. As is often the case, this is because I’ve been too busy to devote time to this site (or anything RISC OS-related in general).

Wishing the ARM processor a happy 30th birthday

Today, 26th April, 2015 isn’t just the morning after this year’s Wakefield Show; it is also 30 years to the day since the very first ARM1 processor was produced, powered up – and worked! The story of the new processor goes back a little further than 26th April, 1985, and started when Acorn were looking for a suitable replacement for the MOS 6502 CPU, which at that point they were using in the BBC Microcomputer range.
