RISC OS is the superbly efficient operating system designed in the 1980's by Acorn Computers, and its latest incarnation is used by thousands of people around the world. However, many may never have even heard of RISC OS - so if you're one of them, you've come to the right place.
Pre-dating both Windows and Mac OS to use a task bar or 'Dock', RISC OS includes many revolutionary features which are only just being copied by other systems. Its anti-aliased font technology is still the envy of the computer world and its drag 'n' drop, stackable windows GUI, flexibility and ease of use make it arguably the most productive computer system in the world today.
Thousands of applications and utilities are available, often developed by small companies and individual users, mean that you should be able to find software on RISC OS to cater for all your computing requirements. It is hoped that new developers will come on board to help promote and enhance RISC OS even more.
RISCOS.org seeks to not only introduce newcomers and experts alike to this wonderful system, but to act as a resource centre and help forum for existing users around the world. Our software database is probably the most comprehensive repository of RISC OS links anywhere on the internet, and we update it frequently with new releases.
News Headlines from the RISC OS world
[27th Oct 2008] Latest Intel chips still can't match ARM for power saving - Intel issued a "correction" Thursday regarding comments one of its executives made earlier this week slamming the iPhone as incapable of working correctly with the internet.
Among other things, the executives accused ARM chips of being unable to "handle the internet" and singled out the iPhone as an example of a smart phone that could be really great if it used one of Intel's low-power x86 architecture processors, known as Atom.
More Info: Silicon.com- [12th Oct 2008] Major new RISC OS application in development - Long-term RISC OS devotee Paul Vigay has recently announced a new application he's currently working on. With a development version to be demonstrated at the forthcoming RISC OS SE Show, WebAnim8r is a powerful and comprehensive application for creating animations and graphics suitable for including on websites and presentations.
A flexible built-in scripting language allows the user to create complex designs with the aid of simple keywords, or fall back on the intuitive user interface.
More Info: WebAnim8r homepage - [27th Sep 2008] End of the line for Iyonix - From 30th September it will no longer be possible to purchase an Iyonix computer. After 15 years of business, Jack Lillingston and John Ballance would like to thank all their customers for their support. There are still limited supplies of Iyonix computers available, so order one now as remaining stock is available on a first come, first served basis. From 1st October, support for the Iyonix will continue through the Iyonix dealer network, website and email.

RISC OS Open
London is closer than you think
This year’s London show organised by ROUGOL is this Saturday the 25th October from 11am. Shows are the perfect opportunity to meet and talk to fellow RISC OS users and developers about what they’re doing with our favourite operating system.Venue detailsA short distance by public transport, around ten miles from Heathrow airport, less than four miles from the M1 motorway, the Harrow District Masonic Centre is closer than you think; see this Google map for directions.Please note: engineering work means the Bakerloo tube line is closed this weekend.See BASIC in actionSee the alpha version of BBC BASIC rewritten in C, running natively on both RISC OS 5 and Windows x64, and find out what’s required to get it all finished. It’s a considerable technical effort, and will pave the way for all kinds of language extensions in future.Want to know why nightly builds of BASIC gained a new SYS-as-a-function keyword recently? It’s all part of the mission to the moon.

Streaming Video in 1994?
In 1994, Acorn Computers, through its Online Media division, played a central role in one of the earliest practical demonstrations of video-on-demand over a broadband network. The Cambridge (UK) Digital Interactive Television Trial, developed in collaboration with Anglia Television, Cambridge Cable (now Virgin Media), and Advanced Telecommunication Modules Ltd (ATML), anticipated many of the features that would later become standard in streaming media.

Pi memory freed from its 32 bit shackles
The period between stable releases is the perfect time to try out some experimental changes to RISC OS. If you’ve bought one of the top-of-the-range Raspberry Pi 4’s with 4GB or 8GB of RAM the good news is that that extra memory can now be unlocked by dropping the Beta RPi ROM (8GB Support) onto your SD card.

Moonshots Rocket is Fuelling Up
Back in March the Moonshots Initiative outlined an ambitious plan to migrate the source code of RISC OS away from hand crafted assembler to reach a 64-bit destination before all the 32-bit chips run out. Already the initiative has generated a number of people asking to be involved, promising leads in the areas of focus, and we’re grateful to have received some financial donations from the community already.

Get ready to squint! World's smallest pixel is just 300 nm
How many 1080p screens can you fit on a pinhead? These German physicists reckon about one
Micro-OLED displays with 1080p (1920x1080) resolution have been around for a few years now, but a group of German researchers has taken things to the next level. They've engineered an OLED pixel so small that an entire 1080p display could fit into a single square millimeter, potentially changing the game for wearable displays.Python Foundation goes ride or DEI, rejects government grant with strings attached
