The Iyonix PC was an Acorn-clone personal computer sold by Castle Technology and Iyonix Ltd between 2002 and 2008. According to news site Slashdot , it was the first personal computer to use Intel's XScale processor. [5] It ran RISC OS 5 . [6]
The Iyonix originated as a secret project by Pace engineers in connection with development of set-top boxes (STBs),[ citation needed ] and has been noted as a successor to the RiscPC . [7] Pace had a licence to develop RISCOS Ltd's OS sources for use in the STB market. The Iyonix was developed under the code name Tungsten and uses RISC OS 5 , which is a version of RISC OS that supports ARM CPUs with 32-bit addressing modes. The sources and hardware design were subsequently acquired by Castle, who developed them into the final product. [8] Castle continued to keep the project a secret, requiring developers to sign a non-disclosure agreement. Information was distributed to such developers via a confidential section of the website. [9] Customers were occasionally able to buy the computer as a bare bones system for self-assembly. [10]
After speculation on the usenet newsgroups, a website for the hardware was spotted in mid October 2002. [11] Units first went on sale in December 2002. [12] Prices started from £1249. [13]
Castle ceased production of the Iyonix after the July 2006 introduction in the UK of the RoHS Regulations. The design was not compliant [14] and Castle did not redesign the Iyonix. Sales continued for another two years via a newly established company, Iyonix Ltd, which enabled Castle itself to circumvent the regulations. [8]
On 25 September 2008, Castle announced that production of the Iyonix had ceased and that new units would no longer be available to order. [15]
Features include:
It was the first time substantial changes had been made to the platform since the release of the Risc PC in 1994. All interim machines had been built on the ARM7500 system on a chip, which was widely regarded as a single-chip Risc PC. (It incorporated the memory controller, video, sound, IO and CPU logic of a Risc PC, leaving only memory and disc interfacing to be added.)
The presence of PCI and USB capabilities, as well as the retained "podule" bus, attracted comparisons to Acorn's aborted Phoebe PC; however, such comparisons should be tempered with Phoebe's proposed feature set, which retained VIDC and 26-bit mode, and although Phoebe was intended to be capable of SMP configurations, its proposed shipping configuration had been for one SA110 CPU.
The Risc PC is Acorn Computers's RISC OS/Acorn RISC Machine computer, launched on 15 April 1994, which superseded the Acorn Archimedes. The Acorn PC card and software allows PC compatible software to be run.
XScale is a microarchitecture for central processing units initially designed by Intel implementing the ARM architecture instruction set. XScale comprises several distinct families: IXP, IXC, IOP, PXA and CE, with some later models designed as system-on-a-chip (SoC). Intel sold the PXA family to Marvell Technology Group in June 2006. Marvell then extended the brand to include processors with other microarchitectures, like ARM's Cortex.
RISC OS is a computer operating system originally designed by Acorn Computers Ltd in Cambridge, England. First released in 1987, it was designed to run on the ARM chipset, which Acorn had designed concurrently for use in its new line of Archimedes personal computers. RISC OS takes its name from the reduced instruction set computer (RISC) architecture it supports.
The Phoebe 2100 was to be Acorn Computers' successor to the RiscPC, slated for release in late 1998. However, in September 1998, Acorn cancelled the project as part of a restructuring of the company.
RISC iX is a discontinued Unix operating system designed to run on a series of workstations based on the Acorn Archimedes microcomputer. Heavily based on 4.3BSD, it was initially completed in 1988, a year after Arthur but before RISC OS. It was introduced in the ARM2-based R140 workstation in 1989, followed up by the ARM3-based R200-series workstations in 1990.
Castle Technology Limited, named after Framlingham Castle, was a British computer company based in Cambridge, England. It began as a producer of ARM computers and manufactured the Acorn-branded range of desktop computers that run RISC OS.
The A9home was a niche small-form-factor desktop computer running RISC OS Adjust32. It was officially unveiled at the 2005 Wakefield Show, and is the second commercial ARM-based RISC OS computer to run a 32-bit version of RISC OS. When the Iyonix PC was withdrawn from sale, the A9home remained the only hardware to be manufactured specifically for the RISC OS marketplace.
The A7000 and A7000+ were Acorn Computers' entry level computers based somewhat on the Risc PC architecture.
Sam440, also known by Sam or its codename Samantha, is a line of modular motherboards produced by the Italian company ACube Systems Srl. The Sam440ep version is a motherboard based on the PowerPC 440EP system-on-a-chip processor which includes a double-precision FPU. It is made by AMCC. Their primary targets are the industrial and embedded markets, running operating systems such as Linux and AmigaOS 4.
RISC OS Open Ltd. is a limited company engaged in computer software and IT consulting. It is managing the process of publishing the source code to RISC OS. Company founders include staff who formerly worked for Pace, the company which acquired RISC OS after Acorn's demise.
RISCOS Ltd. was a limited company engaged in computer software and IT consulting. It licensed the rights to continue the development of RISC OS 4 and to distribute it for desktop machines from Element 14 and subsequently Pace Micro Technology. Company founders include developers who formerly worked within Acorn's dealership network. It was established as a nonprofit company. On or before 4 March 2013 3QD Developments acquired RISCOS Ltd's flavour of RISC OS. RISCOS Ltd was dissolved on 14 May 2013.
Drobe was a computing news web site with a focus on the RISC OS operating system. Its archived material was retained online, curated by editor Chris Williams until late 2020.
Acorn Arcade is a computing resource website with a focus on the RISC OS operating system and its gaming scene. It has been recognised by Acorn User magazine and was an award winner at the Wakefield Acorn Computer Show.
The Icon Bar is a computing and technology website with a focus on the RISC OS computer operating system.
Acorn C/C++ is a set of C/C++ programming tools for use under the RISC OS operating system. The tools use the Norcroft compiler suite and were authored by Codemist and Acorn Computers. The tools provide some facilities offered by a fully integrated development environment.
RISC OS, the computer operating system developed by Acorn Computers for their ARM-based Acorn Archimedes range, was originally released in 1987 as Arthur 0.20, and soon followed by Arthur 0.30, and Arthur 1.20. The next version, Arthur 2, became RISC OS 2 and was completed and made available in April 1989. RISC OS 3 was released with the very earliest version of the A5000 in 1991 and contained a series of new features. By 1996 RISC OS had been shipped on over 500,000 systems.
The MicroDigital Omega was a home computer developed and sold in the early 2000s by MicroDigital. It runs the RISC OS operating system.
VirtualAcorn is the brand name of several commercial emulators of Acorn Computers computer hardware platforms.
In computing, Aemulor is an emulator of the earlier 26-bit addressing-mode ARM microprocessors. It runs on ARM processors under 32-bit addressing-mode versions of RISC OS. It was written by Adrian Lees and released in 2003. An enhanced version is available under the name Aemulor Pro.
