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. -

4. the BBC BASIC Assembler
ARM Assembly Language Programming - Chapter 4 - The BBC BASIC Assembler 4. The BBC BASIC Assembler There are two main ways of writing ARM assembly language programs. One is to use a dedicated assembler. Such a program takes a text file containing ARM assembly language instructions, assembles it, and produces another file containing the equivalent machine code. These two files are called the source files and object files respectively. An alternative approach is to use the assembler built-in to BBC BASIC. The ability to mix assembler with BASIC is a very useful feature of the language, and one that is relatively straightforward to use. For this reason, and because of the widespread availability of BBC BASIC, we describe how to use its built-in assembler. The examples of the next two chapters are also in the format expected by the BASIC assembler. 4.1 First principles Two special 'statements' are used to enter and exit from the assembler. The open square bracket character, [, marks the start of assembly language source. Whenever this character is encountered where BASIC expects to see a statement like PRINT or an assignment, BASIC stops executing the program and starts to assemble ARM instructions into machine code. The end of the source is marked by the close square bracket, ]. If this is read where BASIC is expecting to see an instruction to be assembled, it leaves assembler mode and starts executing the (BASIC) program again. To see the effect of entering and leaving the assembler, type in this short program: 10 PRINT "Outside the assembler" 20 [ ;In the assembler 30 ] 40 PRINT "Outside the assembler" If you RUN this, you should see something like the following: Outside the assembler 00000000 ;In the assembler Outside the assembler Between the two lines produced by the PRINT statements is one which the assembler printed. -

Updated Virtualrpc Components for RISC OS 6
ne of the main things that keeps me using my Risc PC is the versatility of the operating system - mainly due to it’s universal draw file format. For Oinstance I construct the centre pages in Artworks as this now has excellent PDF export facilities. However for proofing the magazine before it gets sent to the printers I like to do a printout to see if everything works properly. Because Artworks now can deal with multiple pages it is very easy to save each page either as an Artworks file or Draw file directly into the magazine’s Ovation Pro file by dragging and dropping. A two second job! Other computer platforms don’t generally have this facility of moving files directly into open application windows. Generally to move a file to another application you have to use the dreaded ‘save as’ filer window - choose a suitable format - navigate to where you need to save the file - save it - go to the other application - open a filer window - navigate to the saved file - open it in the new application. If you need to transfer a different file type you generally have to go through all that palaver again. Two seconds on RISC OS, thirty seconds on OS X or Windows. Draw is a great program with no real equivalent on a PC or Mac. For instance it can be put to good use in music for constructing objects the original program can’t do. I use the Sibelius music setting program on both RISC OS and Windows. The RISC OS still has one or two advantages over the PC version, one of which is it’s ability to export to Draw. -

Linux Kernel Series
Linux Kernel Series By Devyn Collier Johnson More Linux Related Stuff on: http://www.linux.org Linux Kernel – The Series by Devyn Collier Johnson (DevynCJohnson) [email protected] Introduction In 1991, a Finnish student named Linus Benedict Torvalds made the kernel of a now popular operating system. He released Linux version 0.01 on September 1991, and on February 1992, he licensed the kernel under the GPL license. The GNU General Public License (GPL) allows people to use, own, modify, and distribute the source code legally and free of charge. This permits the kernel to become very popular because anyone may download it for free. Now that anyone can make their own kernel, it may be helpful to know how to obtain, edit, configure, compile, and install the Linux kernel. A kernel is the core of an operating system. The operating system is all of the programs that manages the hardware and allows users to run applications on a computer. The kernel controls the hardware and applications. Applications do not communicate with the hardware directly, instead they go to the kernel. In summary, software runs on the kernel and the kernel operates the hardware. Without a kernel, a computer is a useless object. There are many reasons for a user to want to make their own kernel. Many users may want to make a kernel that only contains the code needed to run on their system. For instance, my kernel contains drivers for FireWire devices, but my computer lacks these ports. When the system boots up, time and RAM space is wasted on drivers for devices that my system does not have installed. -
