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 linux 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 window. 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.

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 patch 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 Computer operating system was first used in Acorn Archimedes computers in 1987. Acorn Computers 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 software releases. Within the last 13 years RISC OS was developed intensively and is used in leading computer models of Castle Technology, 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 hard disk drive. 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.

  • So What's the A6 Computer from STD Really Like?

    So What's the A6 Computer from STD Really Like?

    Front cover and reprint by kind permission of Qercus magazine. So what's the A6 computer from STD really like? (A reprint from Qercus issue 268) The A6 What is the A6? The A6 is a new generation of RISC OS computer. It is based around a high-specification PC running Windows XP. An emulation environment called VirtualRPC enables this machine to appear to RISC OS as if it is a traditional RiscPC machine, and so normal RISC OS applications can be run. Can I run all RiscPC applications? Virtually all, yes. The exception are those which rely on direct access to the parallel or serial ports such as the dongled versions of Impression, although the non-dongled versions work fine, and some modem diallers - internet connections are provided by the emulation environment via the internal modem or network interface. How fast? The A6 will generally run user applications much more quickly than the fastest StrongARM RiscPC. Applications which rely on the transfer of large amounts of data, such as DTP or graphics manipulaton will perform faster still. Such applications also benefit from 8MB of "VVRAM", which means that large screenmodes in true colour are no problem. Our new A6+ offers further enhancements and even better performance - see the last page of this leaflet for details. You're biased! Yes, we are - we specified the A6 to offer an ideal RISC OS emulation environment and we're proud of our achievements. But don't take our word for it - enclosed is a copy of a review of the A6 computer which originally appeared in Qercus issue 268.

Supported Image Formats PrivateEye converts images as necessary into a JPEGs RISC OS-native format. This means that GIFs, PNGs and (optionally) JPEGs are converted into Sprite format when RISC OS’s SpriteExtend module, version 0.99 or later, is used they are loaded. to directly display JPEGs. This allows images larger than available free memory to be displayed by decompressing The converted image is referred to as the display image. and plotting on the fly. Operations such as saving, rotation and the effects system operate on the display image only. Progressive (multiple scan) JPEGs are supported. PrivateEye has an inbuilt version of jpegtran which automatically Sprites converts JPEGs into a baseline format that SpriteExtend can render.
  • Wakefield 2006 RISC OS Computer Show

    Wakefield 2006 RISC OS Computer Show

    I would like to welcome you all to this, our eleventh annual show in Wakefield. There have been many ups and downs over the last eleven years, since the first show at Cedar Court, organised in thirteen weeks, which ended up taking over the entire hotel. Ever since then, we have been at our current venue of Thornes Park. Over the years we have had many interesting attractions and features, such as the guest appearance by Johnny Ball one year. Of course, the show has seen many new hardware and software launches and previews over the years, some more successful then others: Kinetic, Peanut, Phoebe, StrongARM, Vantage, RiScript and so on. In fact, this year it is ten full years since we saw the very first StrongARM at the first Wakefield Show, as well as being the 25th Anniversary of the BBC Micro! Even now, we still have people developing for this famous microcomputer, which helped to start the home computer revolution. Be sure to visit both the JGH BBC Software and Domesday System stands during your visit. The Domesday Project is another superb example of how advanced we were with the BBC Master and other Acorn products of the 1980s. Now we are looking to the future with the new A9home, which is expected to be on retail sale or available for ordering at the show. Over the years we have had visitors to the show from all over the world, from countries such as New Zealand, Australia, South Africa, Belgium, Finland, Sweden and the USA; not bad for an amateur show! Another long-standing attraction of the show is of course the charity stall, which allows redundant equipment to be recycled, and through your kind support the stall has raised many thousands of pounds, primarily for the Wakefield Hospice, over the years.

    Improving the Beaglebone Board with Embedded Ubuntu, Enhanced GPMC Driver and Python for Communication and Graphical Prototypes

    Final Master Thesis Improving the BeagleBone board with embedded Ubuntu, enhanced GPMC driver and Python for communication and graphical prototypes By RUBÉN GONZÁLEZ MUÑOZ Directed by MANUEL M. DOMINGUEZ PUMAR FINAL MASTER THESIS 30 ECTS, JULY 2015, ELECTRICAL AND ELECTRONICS ENGINEERING Abstract Abstract BeagleBone is a low price, small size Linux embedded microcomputer with a full set of I/O pins and processing power for real-time applications, also expandable with cape pluggable boards. The current work has been focused on improving the performance of this board. In this case, the BeagleBone comes with a pre-installed Angstrom OS and with a cape board using a particular software “overlay” and applications. Due to a lack of support, this pre-installed OS has been replaced by Ubuntu. As a consequence, the cape software and applications need to be adapted. Another necessity that emerges from the stated changes is to improve the communications through a GPMC interface. The depicted driver has been built for the new system as well as synchronous variants, also developed and tested. Finally, a set of applications in Python using the cape functionalities has been developed. Some extra graphical features have been included as example.
