Risc PC
The Risc PC is Acorn Computers's RISC OS/ Acorn RISC Machine computer, launched on 15 April 1994, which superseded the Acorn Archimedes.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. Like the Archimedes, the Risc PC continues the practice of having the RISC OS operating system in a ROM module. Risc PC augments the ROM-based core OS with a disk-based directory structure containing configuration information, and some applications which had previously been kept in ROM. At the 1996 BETT Educational Computing & Technology Awards, the machine was awarded Gold in the hardware category. Technical specifications Use The Risc PC was used by music composers and scorewriters to run the Sibelius scorewriting software. Between 1994 and 2008, the Risc PC and A7000+ were used in television for broadcast automation, programmed by the UK company OmniBus Systems: once considered "the world leader in television station automation" and at one point automating ...

Acorn Archimedes
Acorn Archimedes is a family of personal computers designed by Acorn Computers of Cambridge, Cambridge, England. The systems are based on Acorn's own ARM architecture processors and the proprietary operating systems Arthur and RISC OS. The first models were introduced in 1987, and systems in the Archimedes family were sold until the mid-1990s. ARM's Reduced instruction set computer, RISC design, a 32-bit CPU (using 26-bit addressing), running at 8 Hertz, MHz, was stated as achieving 4.5+ Million instructions per second, MIPS, which provided a significant upgrade from 8-bit home computers, such as Acorn's previous machines. Claims of being the fastest micro in the world and running at 18 MIPS were also made during tests. Two of the first models—the A305 and A310—were given the BBC branding, with BBC Worldwide, BBC Enterprises regarding the machines as "a continuing part of the original computer literacy project". Dissatisfaction with the branding arrangement was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The acorn, or oaknut, is the nut of the oaks and their close relatives (genera ''Quercus'' and ''Lithocarpus'', in the family Fagaceae). It usually contains one seed (occasionally two seeds), enclosed in a tough, leathery shell, and borne in a cup-shaped cupule. Acorns are long and on the fat side. Acorns take between 5 and 24 months (depending on the species) to mature; see the list of ''Quercus'' species for details of oak classification, in which acorn morphology and phenology are important factors. Etymology The word ''acorn'' (earlier ''akerne'', and ''acharn'') is related to the Gothic name ''akran'', which had the sense of "fruit of the unenclosed land". The word was applied to the most important forest produce, that of the oak. Chaucer spoke of "achornes of okes" in the 14th century. By degrees, popular etymology connected the word both with "corn" and "oak-horn", and the spelling changed accordingly. The current spelling (emerged 15c.-16c.), derives from assoc ...

RISC OS Open
RISC OS Open Ltd. (also referred to as ROOL) 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. The source code publication was initially facilitated by a shared source initiative (SSI) between ROOL and Castle Technology (CTL), prior to a switch to the more widely recognised Apache licence in October 2018. ROOL hopes that by making the RISC OS source code available for free it will help stimulate development of both the RISC OS source code and the platform as a whole. Operations ROOL set initial goals to make the source code easily available (on the web), and also to establish a wiki, forum and bug tracker. These have been available since December 2006. Operations exist to facilitate tasks related to ROOL's goals. Additionally, staff undertake development work on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RISCOS Ltd
RISCOS Ltd. (also referred to as ROL) was a limited company engaged in computer software and IT consulting. It licensed the rights to continue the development of and to distribute it for desktop machines (as an upgrade or for new 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. History RISCOS Ltd was formed to continue end-user-focused development of RISC OS after the de-listing of Acorn Computers, following its purchase by Morgan Stanley Dean Witter in order to benefit from the shareholding that Acorn held in ARM Ltd. In March 1999, RISCOS Ltd obtained exclusive rights to develop and sell RISC OS 4 for the desktop market from Element 14. A few weeks later Pace purchased Acorn's Cambridge headquarters ...

Eurocard (printed Circuit Board)
Eurocard is a European standard format for printed circuit board (PCB) cards that can be plugged together into a standard chassis which, in turn, can be mounted in a 19-inch rack. The chassis consists of a series of slotted card guides on the top and bottom, into which the cards are slid so they stand on end, like books on a shelf. At the spine of each card is one or more connectors which plug into mating connectors on a backplane that closes the rear of the chassis. Dimensions As the cards are assumed to be installed in a vertical orientation, the usual meanings of height and width are transposed: A card might be 233.35 mm "high", but only 20 mm "wide". Height is measured in rack units, "U", with 1 U being . This dimension refers to the subrack in which the card is to be mounted, rather than the card itself. A single card is 100 mm high. Taller cards add a 133.35 mm, so that a double height card is 233.35 mm high and a triple 366.7 mm high. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
VIDC20
The VIDC20 was a video display controller chip created as an accompanying chip to the ARM CPU as used in RiscPC computer systems. A simpler version of the VIDC20, the VIDC1, was used in the earlier Acorn Archimedes Acorn Archimedes is a family of personal computers designed by Acorn Computers of Cambridge, England. The systems are based on Acorn's own ARM architecture processors and the proprietary operating systems Arthur and RISC OS. The first mode ... computers. A VIDC20 chip controls both the computer's video and sound. The data is read from the 64-bit ARM data bus using DMA control and then processed and converted into the necessary analogue signals to drive the video output displays and sound system. The VIDC20 can handle many more display and sound formats than the original VIDC1 chip found in the Archimedes hardware. It can also read data from VRAM if installed in the machine, otherwise it reads from DRAM. Video Data from the video buffer is converted and proces ...

SIMM
A SIMM (single in-line memory module) is a type of memory module containing random-access memory used in computers from the early 1980s to the early 2000s. It differs from a dual in-line memory module (DIMM), the most predominant form of memory module since the late 1990s, in that the contacts on a SIMM are redundant on both sides of the module. SIMMs were standardised under the JEDEC JESD-21C standard. Most early PC motherboards (8088-based PCs, XTs, and early ATs) used socketed DIP chips for DRAM. As computer memory capacities grew, memory modules were used to save motherboard space and ease memory expansion. Instead of plugging in eight or nine single DIP chips, only one additional memory module was needed to increase the memory of the computer. History SIMMs were invented in 1982 by James J. Parker at Zenith Microcircuits and the first Zenith Microcircuits customer was Wang Laboratories. Wang Laboratories tried to patent it and were granted a patent in April 1987. Th ...

Digital Signal Processor
A digital signal processor (DSP) is a specialized microprocessor chip, with its architecture optimized for the operational needs of digital signal processing. DSPs are fabricated on MOS integrated circuit chips. They are widely used in audio signal processing, telecommunications, digital image processing, radar, sonar and speech recognition systems, and in common consumer electronic devices such as mobile phones, disk drives and high-definition television (HDTV) products. The goal of a DSP is usually to measure, filter or compress continuous real-world analog signals. Most general-purpose microprocessors can also execute digital signal processing algorithms successfully, but may not be able to keep up with such processing continuously in real-time. Also, dedicated DSPs usually have better power efficiency, thus they are more suitable in portable devices such as mobile phones because of power consumption constraints. DSPs often use special memory architectures that are able t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IBM 5x86C
The Cyrix 5x86 was a line of x86 microprocessors designed by Cyrix and released on June 5 of 1995. Cyrix, being a fabless company, had the chips manufactured by IBM. The line came out about 5 months before the more famous Cyrix 6x86. The Cyrix 5x86 was one of the fastest CPUs ever produced for Socket 3 computer systems. With better performance in most applications than an Intel Pentium processor at 75 MHz, the Cyrix Cx5x86 filled a gap by providing a medium-performance processor option for 486 Socket 3 motherboards (which are incapable of handling Intel's Pentium CPUs, apart from the Pentium Overdrive). The IBM 5x86C is an IBM branded and produced version of the Cyrix-designed Cyrix Cx5x86 CPU. Previous IBM x86 processors, IBM 386SLC and IBM 486SLC, were based on modified Intel designs. Design The Cyrix 5x86 processor, codename "M1sc", was based on a scaled-down version of the "M1" core used in the Cyrix 6x86, which provided 80% of the performance for a 50% ...
