Note: RISC OS Select ROM image files are not usable directly as they are compressed. To use them please boot them and use the 'Extract from a running RISC OS machine' instructions below. Alternative if you have a machine, use this method to decompress them. The only acceptable sizes for ROM images (in total) are 2MB, 4MB and 6MB. Availability. Binary downloads. Binary copies of RISC OS ROM images may be available from the following sites. Extract from running RISC OS machine. You can extract a ROM image from a running RISC OS machine using the following commands from a command prompt or task . This will save 4 megabytes of ROM, later versions of RISC OS Select are 6 megabytes in size, so need to be saved differently. Installation. These files should then be copied to the machine running RPCEmu and placed in the 'roms' directory. RPCEmu. RPCEmu requires a RISC OS ROM image to work, find details of where to find one. RPCEmu should be considered Alpha Quality code. It has many known and unknown bugs, and all files used with it should be well backed up before using them with RPCEmu. Documentation.

Two ROM/Disc Image sets are now available to make setting up RPCEmu as simple as possible. both are configured with networking by default. RISC OS Direct, a version of the RISC OS 5 based distribution with many extras, ideal for running recent applications RISC OS 3.71, an older '26-bit' version of RISC OS, ideal for running 'classic' applications. Correct several issues related to the MSR instruction Correct several instruction decoding issues Generate undefined instruction exceptions in the correct places of the instruction set Implement ARMv4 (StrongARM) Load store extensions Make ARMv4 extensions only available when configured as ARMv4 We now support loading of DOS and Atari 360KB (.img) disc images into the floppy drives. Settings files and CMOS ram files are saved as changes are made to them, so these settings are retained even if the program is closed abnormally. Developer Information. We're very happy for RPCEmu to accept code and contributions from third parties, already many people have contributed code and we hope to continue down this route. The RPCEmu source is stored inside the Mercurial version control system, Mercurial clients are available for many platforms, including (but not limited to) Windows, Linux, Mac OS X, Solaris, BSDs. If you are used to a different version control system, such as CVS or SVN, Mercurial (as a distributed version control system) may seem a little odd, but there are plenty of tutorials and advice for users coming from other systems on the web. The Mercurial repository is based at. and checking out the code is as simple as. How to get code committed into the repository. Prepare a file of the differences between your new code and the current 'HEAD' of the project. Mercurial provides the 'hg diff' command, which generates diff files suitable for this. Then post this patch file to the mailing list (or to us directly if you so wish), with an explanation of what it's for, and in the case of bug fixes, the bug it's meant to fix (it's not always obvious from the code) Generally the smaller the patch, with the most specific function or reason, the easier the patch is to merge in, whereas a "I fixed everything I thought was wrong" would take a very long time to verify and test. Patches may get edited before being committed, or if the changes required are particularly large an updated patch may be requested of the developer. In some rare cases it might not be possible to commit a patch, and at that point there should be a stated reason (e.g. patch overlaps with another patch that deprecates it, patch is too widespread to verify (suggest breaking into smaller patches), etc). If you have any questions, once again the mailing list is the best place to ask, also, if you're considering a particulaly large change, that would affect a large functional area or many files, it might well be worth getting some advice from the developers on the mailing list first, incase it overlaps with other development work, or even just a suggestion of how to accomplish it in smaller changes. Documentation of Operating Systems and Developers. The Reduced Instruction Set operating system was first used in in 1987. Ltd. developed her own 32-bit RISC processor, the Acorn Risc Machine (ARM), to fulfil her needings. ARM processors do not need an active fan because they have a very little power assumption in opposite to x86 processors and a much lower thermal heating. RISC OS needs only a ROM and is protected from data damage (e.g. by viruses) reliably. Compared with most other operating systems this is an special feature. To upgrade the operating system the OS ROMs got simply replaced, newer RISC OS Computers have FlashROMs and can be upgraded to the newest stand without hardware interaction. Pace Micro Technology plc is owner of RISC OS latest since 1999 and has handed over the further development to the company RISCOS Ltd. by now. This firm develops new releases. Within the last 13 years RISC OS was developed intensively and is used in leading computer models of , RiscStation and MicroDigital. The fields of application of RISC OS lie obviously in the graphic industry, word processing and the education market. Numerous ported programming languages are available for the development of new applications. An ambitious project pursues www.explan.co.uk with high economic computers and RISC OS for use in developing countries. A9home is a good example of the energy-saving and compact design of a complete computer. The energy consumption is covered with 2 to 3 watt. A 400 MHz Samsung ARM9 processor is used, 128 mbyte SDRAM, 8 mbyte VRAM and a 40 GByte . Update: 2003-04-07 Castle Technology Ltd. takes over Pace Micro Technology plc. with the whole RISC OS technology. In addition, Castle came in a joint venture with Tematic Ltd. to develop an embedded version of RISC OS. Update 2007-05-19 The company Castle Technology published first parts of the source code of RISC OS 5.12 for ARM architecture on the web site www.riscosopen.org, this is protected by a own shared source licence. System Features. RISC OS is a special and efficient operating system. Many hardware and software functions became differently in comparison with Mac OS/Apple Mac or Windows/IBM PC, however, this does not derive direct disadvantages. Driver software for extensions are integrated in the ROM and can be tied by Plug & play in the operating system. In the daily usage it behaves very stably since it was tested extensively and has proved itself worldwide. Not at least the narrow coupling of the operating system to the computer provides the perfect cooperation. If nevertheless once an application should crash, it can be removed from memory without complete system crash. The source code was written manually in large parts and optimized for the ARM. RISC OS needs only 4 MB of storage in the ROM, the extension with a fixed disk as well as creating of virtual RAM disks is possible. Moreover, to protect the system, the CMOS RAM and the fixed disk can be protected by a password to avoid changes. The procedure after a cold start takes fewer than 30 seconds. You can select between the BBC BASIC mode, desktop mode and command line as . RISC OS is modularized and supports software modules which can be added to the system. The multitasking GUI has been standard for the RISC OS for 13 years because of the very user friendly and effectively in this daily use. With the-bitmap optimized printing manager makes very good print results, character fonts are smoothed with anti-aliasing. Standard applications on every RISC OS are Edit for word processing, Paint for-bitmap pictures and Draw for vector pictures which are based on up to 24-bit color resolution. 16-bit Sound support are included as well as the native support of long file names. The file management allows storing of arbitrary many files in directories. Special character like "/ ! $ Dollar %" are useable for file names without restrictions. With a 3-key mouse they can be made versatile interactions on the desktop possible, so e.g. menus are invoked comfortably with the middle in all windows. The windows and the desktop supports general Drag & Drop just like the clipboard applies to the complete system. RISC OS os is flexible, the complete system configurations can be done on the command line. Compact applications like EasiWriter Professional+, comparably with Word, needs only 1,101 Kbyte of storage and 860 Kbyte of RAM. Temporary files are never needed and created. Moreover, RISC OS supports DPMS (Display Power Management Signalling) and offers with the built-in BBC BASIC the own ARM assembler. The simple TCP/IP support opens the Internet to the user. Characteristics. - Browser with HTML 3.2, CSS, SVG, JavaScript, Flash - Supports FAT, ADFS, ISO9660, further FS are reloadable - 26-bit addressing prevents the use of newer 32-bit CPUs - addressing only by additional software - dynamic storage management - , modularized code blocks - only - manages files after type not after extension - no multithreading possible - only few games available - no support. RISC OS Software. This page contains software I originally wrote for Acorn's series of RISC OS computers. I haven't owned or used a RISC OS machine for over a decade, and these pages had over time disappeared from my website. I recently learned that RISC OS is becoming popular again as an operating system for the , the cheap, ARM-powered hobbyist computer that in some ways is a modern successor to Acorn's BBC Computers. Therefore, I am pleased to reinstate these old pages, largely unaltered from how they appeared 10 years ago, to allow a new generation of RISC OS users to download my prgorams, in the hope they may find them useful. Please note that this software was written for much earlier versions of RISC OS than is available for the Raspberry Pi, and for a processor with a 26-bit address register. Most are written in simple BASIC, so I expect them to work, but some may not function correctly. As I no longer use RISC OS, I can only offer limited support. As an aside, while Acorn disappeared a long time ago, the ARM processor they originally designed has become a huge success as it is used not only in the Raspberry Pi, but also in virtually all smartphones on the market. Arguably, the iPhone would not exist in its current form if RISC OS hadn't been created. Now, if only I'd ignored the usual investment advice about sentimentality a decade ago and had bought ARM shares, I could have seen my money increase six-fold. Software index. Please select one of the categories from the list below: Downloading information. Each application available for downloading is listed along with its latest version number and compressed file size. Many of the applications' Help files are available as web pages so that you can decide if it is worth downloading the whole application. The applications are stored as zip files. To use them, you will need a program to 'unzip' them. If you do not already have such a program, you can download SparkPlug from David Pilling's web site. Once Sparkplug is on the iconbar, simply drag the downloaded zip file to it. A window will appear with the application inside it. To use the application, you must copy it to another directory.

Here at Ident Computer, we've adopted RISC OS 5 as our prime OS environment, mainly because version 5 is open source, free to use, is very fast - (even on the slowest Raspberry Pi boards), has the powerful BBC BASIC programming language underpinning it and is very easy to understand and use. The Wi-FI Sheep build of RISC OS has now been superseded by RISC OS Direct an official distribution from RISC OS Developments Ltd. And can be downloaded for free from: Ideal for beginners of all ages to learn how to create programs and software, whist at the same time giving a real useable alternative to Linux or Windows PC platforms. Thanks to recent developments in licensing we can offer for the first time a completely free version of RISC OS 5 for Raspberry Pi computers. And best of all you do NOT need to have been a customer of Ident Computer or Wi-Fi Sheep to download and use! Our Ident Computer / Wi-Fi Sheep edition of RISC OS 5 comes with a few add-on and tweaks that we think you'll love! To RUN RISC OS you will need any Raspberry Pi computer board, a 3 button mouse (clickable centre scroll wheel is fine) and an 8GB or larger SD card (OS needs 7.74GB). Download the zip file to MAC or PC and unpack/uncompress. Use a image writer program such as Etcher to write the IMG OS file to your SD card. A brief history of RISC OS. RISC OS or (Reduced Instruction Set Computing Operating System) was first developed by Acorn computers in the mid to late 1980's for use with Acorn's new high performance processors, the 'ARM' chip. The OS is built on the technology and programming language first used by the Acorn BBC Micro computer in 1981. RISC OS added modern user friendly features to the BBC Micro system such as graphics, icons, cursor and mouse support. The first version of RISC OS was released in 1987 under the code name 'Arthur' and ran on the 'Acorn Archimedes' range of computer systems. After the breakup of Acorn Computers in the late 1990's, development of RISC OS continued for a range of independent computer . In 2012 the 'Raspberry Pi' a low cost ARM based single board computer was released with the sole aim to teach people how to programme computers once more. After its launch in 2012, a number of operating systems were released for the then new Raspberry Pi; one of these was a newly updated and completely free version of RISC OS, known as RISC OS 5. RISC OS is the commercial property of RISCOS Developments Ltd & the stock build is freely available to download from RISC OS OPEN Ltd.
