According to news site Slashdot , it was the first personal computer to use Intel's XScale processor. It ran RISC OS 5 . The Iyonix originated as a secret project by Pace engineers in connection with development of set-top boxes (STBs), and has been noted as

During the search for potential financing partners, an Olivetti director had approached Close Brothers, ostensibly as part of Olivetti's strategy of acquiring technologically advanced small companies. After a short period of negotiations, Curry and Hauser signed an agreement with Olivetti on 20 February. With the founders relinquishing control of

It was time for Wilson to approach Hauser and explain what was afoot. Once the go-ahead had been given, a small team was put together to implement Wilson's model in hardware. Acorn initiated its RISC research project in October 1983, and by 1987 had spent £5 million . VLSI Technology, Inc were chosen as silicon partner, since they already supplied Acorn with ROMs and some custom chips. VLSI produced

Although designed for memory, Secure Digital Input/Output (SDIO) and CompactFlash cards were made available that provided peripheral accessories like Wi-Fi or digital cameras to devices with software support. Some PDAs also have a USB port, mainly for USB flash drives . Some PDAs use microSD cards, which are electronically compatible with SD cards, but have
515-529: A calculator , and some sort of memo (or "note") program. PDAs with wireless data connections also typically include an email client and a Web browser, and may or may not include telephony functionality. Many of the original PDAs, such as the Apple Newton and Palm Pilot , featured a touchscreen for user interaction, having only a few buttons—usually reserved for shortcuts to often-used programs. Some touchscreen PDAs, including Windows Mobile devices, had

Initially, the ACE controller was based on a National Semiconductor SC/MP microprocessor, but soon the switch to a MOS Technology 6502 was made. CPU had financed the development of a SC/MP based microcomputer system using the income from its design-and-build consultancy. This system

By the early 2000s, nearly all PDA models had the ability to access the Internet, intranets or extranets via Wi-Fi or Wireless WANs , and since then generally included a web browser . Sometimes, instead of buttons, later PDAs employ touchscreen technology. The first PDA, the Organiser , was released in 1984 by Psion , followed by Psion's Series 3 , in 1991. The latter began to resemble

Acorn had investigated all of the readily available processors and found them wanting or unavailable to them. After testing all of the available processors and finding them lacking, Acorn decided that it needed a new architecture. Inspired by white papers on the Berkeley RISC project, Acorn seriously considered designing its own processor. A visit to

Palm would eventually be the dominant vendor of PDAs until the rising popularity of Pocket PC devices in the early 2000s. By the mid-2000s most PDAs had morphed into smartphones as classic PDAs without cellular radios were increasingly becoming uncommon. A typical PDA has

Brighton and SUSSEX Medical School in the UK was the first medical school to provide wide scale use of PDAs to its undergraduate students. The learning opportunities provided by having PDAs complete with a suite of key medical texts were studied with results showing that learning occurred in context with timely access to key facts and through consolidation of knowledge via repetition. The PDA
1133-493: A business machine looked like a good idea to Acorn. A development programme was started to create a business computer using Acorn's existing technology: the BBC Micro mainboard, the Tube and second processors to give CP/M , MS-DOS and Unix ( Xenix ) workstations. This Acorn Business Computer (ABC) plan required a number of second processors to be made to work with the BBC Micro platform. In developing these, Acorn had to implement

The user interacts with the device by tapping the screen to select buttons or issue commands, or by dragging a finger (or the stylus) on the screen to make selections or scroll. Typical methods of entering text on touchscreen PDAs include: Despite research and development projects, end-users experienced mixed results with handwriting recognition systems. Some found it frustrating and inaccurate, while others were satisfied with
1442-742: A disappointing summer season in 1984, Acorn had evidently focused on making up for lost sales over the Christmas season, with the Electron being a particular focus. However, a refusal to discount the BBC Micro also appeared to inhibit sales of that machine, with some dealers expressing dissatisfaction to the point of considering abandoning the range altogether. With rumours of another, potentially cheaper, machine coming from Acorn, dealers eventually started to discount heavily after Christmas. For instance, high street retailer Rumbelows sought to clear unsold Christmas stocks of around 1500 machines priced at £299, offering
1545-488: A discount of around £100, also bundling them with a cassette recorder and software. The rumoured machine turned out to be the BBC Model B+ which was a relatively conservative upgrade and more, not less, expensive than the machine it replaced. It was speculated that the perception of a more competitive machine soon to be launched might well have kept potential purchasers away from the products that Acorn needed to sell. Acorn
1648-424: A drawn-out and expensive process that proved futile: all of the expansion devices that were intended to be sold with the BBC Micro had to be tested and radiation emissions had to be reduced. It was claimed that Acorn spent £10 million on its US operation without this localised variant of the BBC Micro establishing a significant market share. The machine, however, did make an appearance in the school of Supergirl in
1751-477: A failure to consider local market conditions and preferences, with "complex technical efforts" having been made to make the machine compatible with US television standards when local market information would have indicated that "US home computer users expect to use a dedicated personal computer monitor". Consequently, obtaining Federal approval for the BBC Micro in order to expand into the United States proved to be
1854-615: A follow-up to an ITV documentary , The Mighty Micro , in which Dr Christopher Evans from the UK National Physical Laboratory predicted the coming microcomputer revolution . It was a very influential documentary—so much so that questions were asked in Parliament . As a result of these questions, the Department of Industry (DoI) became interested in the programme, as did BBC Enterprises , which saw an opportunity to sell
1957-654: A larger case with a second drive. The System 5 was largely similar to the System 4, but included a newer 2 MHz version of the 6502 . Development of the Sinclair ZX80 started at Science of Cambridge in May 1979. Learning of this probably prompted Curry to conceive the Atom project to target the consumer market. Curry and another designer, Nick Toop, worked from Curry's home in the Fens on
2060-551: A machine to go with the series. BBC Engineering was instructed to draw up an objective specification for a computer to accompany the series. Eventually, under some pressure from the DoI to choose a British system, the BBC chose the NewBrain from Newbury Laboratories. This selection revealed the extent of the pressure brought to bear on the supposedly independent BBC's computer literacy project—Newbury
2163-442: A market capitalisation of about £135 million. CPU founders Hermann Hauser and Chris Curry's stakes in the new company were worth £64m and £51m, respectively. Ten per cent of the equity was placed on the market, with the money raised from the flotation "mainly" directed towards establishing US and German subsidiaries (the flotation raising around £13.4 million ), although some was directed towards research and product development.

While early PDAs connected to a user's personal computer via serial ports and other proprietary connections , later models connect via a USB cable. Older PDAs were unable to connect to each other via USB , as their implementations of USB did not support acting as the "host". Some early PDAs were able to connect to the Internet indirectly by means of an external modem connected via

It also had an attached telephone, communications software and auto-answer/auto-dial modem. However, with Acorn's finances having sustained the development cost of the Archimedes, and with the custom systems division having contributed substantially to the company's losses in 1987, a change in strategy took effect towards

The company's Acorn Electron , released in 1983, and the later Acorn Archimedes , were highly popular in Britain, while Acorn's BBC Micro computer dominated the educational computer market during
2575-546: A proprietary local area network had been installed at Market Hill. It was decided to include this, the Econet , in the Atom, and at its launch at a computer show in March 1980, eight networked Atoms were demonstrated with functions that allowed files to be shared, screens to be remotely viewed and keyboards to be remotely slaved. After the Atom had been released into the market, Acorn contemplated building modern 16-bit processors to replace
2678-420: A relatively low-cost Ethernet interface card utilising Intel's 82586 network controller chip. Torus later released a network management solution called Tapestry, based on Icon and marketed by IBM for its own networking technologies. Torus also released support for the use of Novell's Advanced Netware product on its own networking hardware. The company eventually entered receivership in 1990 with Acorn reporting
2781-647: A standard for an educational microcomputer system analogous to the MSX computing architecture and to the established IBM PC compatible architecture. Deliberations continued into 1986, with Acorn proposing its own ARM processor architecture as the basis for the initiative, whereas Thomson had proposed the Motorola 68000. Expectations that Olivetti would actively market Acorn's machines in Europe were, however, frustrated by Olivetti's own assessment of Acorn's products as "too expensive" and
2884-507: A successor to the RiscPC . 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. Castle continued to keep

However, some PDAs may not have a touchscreen , using soft keys , a directional pad, and a numeric keypad or a thumb keyboard for input. To have the functions expected of a PDA, a device's software typically includes an appointment calendar , a to-do list , an address book for contacts,
3090-473: A touchscreen or small-scale keyboard was slower than a full-size keyboard. Transferring data to a PDA via the computer was, therefore, a lot quicker than having to manually input all data on the handheld device. Most PDAs come with the ability to synchronize to a computer. This is done through synchronization software provided with the handheld, or sometimes with the computer's operating system. Examples of synchronization software include: These programs allow

Such were the ambitions of Acorn's management that a joint venture company was established in Hong Kong under the name Optical Information Systems , apparently engaging in the development of "digital, optical technology for computer data storage". Involving a Hong Kong turntable manufacturer, Better Sound Reproduction Ltd., Acorn were to set up a research and development facility in Palo Alto, California, US to bring "compact laser disk drives designed as floppy disk drive replacements" to market within 18 months. In February 1985, speculation about

Acorn C/C++ was released commercially by Acorn, for developers to use to compile their own applications. Having become a publicly traded company in 1983 during the home computer boom, Acorn's commercial performance in 1984 proved to be consequential. Many home computer manufacturers struggled to maintain customer enthusiasm, some offering unconvincing follow-up products that failed to appeal to buyers. The more successful manufacturers, like Amstrad, emphasised

CPU purchased Orbis, and Hopper's Orbis shares were exchanged for shares in CPU Ltd. CPU's role gradually changed as its Acorn brand grew, and soon CPU was simply the holding company and Acorn
3708-478: The Computer Conservation Society organised an event at London's Science Museum to mark the legacy of the BBC Micro. A number of the BBC Micro's principal creators were present, and Sophie Wilson recounted to the BBC how Hermann Hauser tricked her and Steve Furber to agree to create the physical prototype in less than five days. Also in 2008 a number of former staff organised a reunion event to mark

After losing control of the company to the NEB, Sinclair encouraged Chris Curry to leave Radionics and get Science of Cambridge (SoC—an early name for Sinclair Research ) up and running. In June 1978, SoC launched a microcomputer kit, the MK14 , that Curry wanted to develop further, but Sinclair could not be persuaded so Curry resigned. During
3914-513: The Western Design Center in the US, where the 6502 was being updated by what was effectively a single-person company, showed Acorn engineers Steve Furber and Sophie Wilson they did not need massive resources and state-of-the-art research and development facilities. Sophie Wilson set about developing the instruction set, writing a simulation of the processor in BBC BASIC that ran on
4017-800: The ZX Spectrum . Curry conceived of the Electron as Acorn's sub-£200 competitor. In many ways a cut-down BBC Micro, it used one Acorn-designed uncommitted logic array (ULA) to reproduce most of the functionality. But problems in producing the ULAs led to short supply, and the Electron, although launched in August 1983, was not on the market in sufficient numbers to capitalise on the 1983 Christmas sales period. Acorn resolved to avoid this problem in 1984 and negotiated new production contracts. Acorn became more known for its BBC Micro model B than for its other products. In 2008,
4120-483: The 1980s. Acorn also developed the reduced instruction set computing (RISC) architecture set in 1985 and an operating system , RISC OS , for the hardware. The company also designed the ARM architecture; this part of the business was spun-off as Advanced RISC Machines under a joint venture with Apple and VLSI in 1990, now known as Arm Holdings , which is dominant in the mobile phone and personal digital assistant (PDA) microprocessor market today.

However, financial troubles led to the company closing down its workstation division in September 1998, effectively halting its home computer business and cancelling development of RISC OS and the Phoebe computer. The company was acquired and largely dismantled in early 1999. In retrospect, Acorn

Acorn's technical staff had not wanted to do the Atom and they now saw the Proton as their opportunity to "do it right". One of the developments proposed for the Proton was the Tube , a proprietary interface allowing a second processor to be added. This compromise would make for an affordable 6502 machine for

Hauser quickly drafted in Steve Furber (who had been working for Acorn on a voluntary basis since the ACE fruit machine project) and Sophie Wilson to help complete a revised version of the Proton which met the BBC's specifications. BBC visited Acorn and were given a demonstration of the Proton. Shortly afterwards,
5150-715: The British Department of Education and Science (DES) had begun the Microelectronics Education Programme to introduce microprocessing concepts and educational materials. In 1981, through to 1986, the DoI allocated funding to assist UK local education authorities to supply their schools with a range of computers, the BBC Micro being one of the most popular. Schools were offered 50% of the cost of computers, providing they chose one of three models: BBC Micro, ZX Spectrum or Research Machines 380Z . In parallel,

Although the NewBrain was under heavy development by Newbury, it soon became clear that they were not going to be able to produce it—certainly not in time for the literacy programme nor to the BBC's specification. The BBC's programmes, initially scheduled for autumn 1981, were moved back to spring 1982. After Curry and Sinclair found out about

RIM sells BlackBerry Enterprise Server to corporations so that corporate BlackBerry users can wirelessly synchronize their PDAs with the company's Microsoft Exchange Server , IBM Lotus Domino , or Novell GroupWise servers. Email, calendar entries, contacts, tasks, and memos kept on the company's server are automatically synchronized with the BlackBerry. The most common operating systems pre-installed on PDAs are: Other, rarely used operating systems: Some PDAs include Global Positioning System (GPS) receivers. Other PDAs are compatible with external GPS-receiver add-ons that use

Newer PDAs, such as the HTC HD2 , Palm Pre , Pre Plus , Pixi , and Pixi Plus , as well as devices running the Android operating system, include more advanced forms of touchscreen that can register multiple touches simultaneously. These " multi-touch " displays allow for more sophisticated interfaces using various gestures entered with one or more fingers. Although many early PDAs did not have memory card slots, later models had either some form of Secure Digital (SD) slot,

Integrated PDA's were fitted as standard on new cars throughout the 2000's. PDA-based GPS can also display traffic conditions, perform dynamic routing, and show known locations of roadside mobile radar guns. TomTom , Garmin , and iGO offered GPS navigation software for PDAs. Some businesses and government organizations rely upon rugged PDAs, sometimes known as enterprise digital assistants (EDAs) or mobile computers , for mobile data applications. These PDAs have features that make them more robust and able to handle inclement weather, jolts, and moisture. EDAs often have extra features for data capture, such as barcode readers , radio-frequency identification (RFID) readers, magnetic stripe card readers, or smart card readers. These features are designed to facilitate

Its first practical application was as a second processor to the BBC Micro, where it was used to develop the simulation software to finish work on the support chips (VIDC, IOC, MEMC) and to speed up the operation of the CAD software used in developing ARM2. The ARM evaluation system was promoted as a means for developers to try
7622-518: The instruction set allowed the code to be very dense, making ARM BBC BASIC an extremely good test for any ARM emulator. Such was the secrecy surrounding the ARM CPU project that when Olivetti were negotiating to take a controlling share of Acorn in 1985, they were not told about the development team until after the negotiations had been finalised. In 1992, Acorn once more won the Queen's Award for Technology for
7725-436: The latter out of a total of 450 employees. Meanwhile, Acorn's chosen method of expansion into West Germany and the United States through the establishment of subsidiaries involved a "major commitment of resources", in contrast with a less costly strategy that might have emphasised collaboration with local distributors. Localisation of the BBC Micro for the US market also involved more expenditure than it otherwise might have due to
7828-508: The literacy programme computer contract was awarded to Acorn, and the Proton was launched in December 1981 as the BBC Micro . In April 1984, Acorn won the Queen's Award for Technology for the BBC Micro. The award paid special tribute to the BBC Micro's advanced design, and it commended Acorn "for the development of a microcomputer system with many innovative features". In April 1982, Sinclair launched
7931-480: The mass market which could be expanded with more sophisticated and expensive processors. The Tube enabled processing to be farmed out to the second processor leaving the 6502 to perform data input/output (I/O). The Tube would later be instrumental in the development of Acorn's ARM processor . In early 1980, the BBC Further Education department conceived the idea of a computer literacy programme, mostly as
8034-589: The more familiar PDA style, including a full keyboard. The term PDA was first used on 7 January 1992 by Apple Inc. CEO John Sculley at the Consumer Electronics Show in Las Vegas , Nevada , referring to the Apple Newton . In 1994, IBM introduced the first PDA with analog cellular phone functionality, the IBM Simon , which can also be considered the first smartphone. Then in 1996, Nokia introduced
8137-484: The portfolio. Even from the time of Acorn's earliest systems, the company was considering how to move on from the 6502 processor, introducing a Motorola 6809 processor card for its System 3 and System 4 models. Several years later in 1985, the Acorn Communicator employed the 16-bit 65816 processor as a step up from the 6502. The IBM PC was launched on 12 August 1981. Although a version of that machine
8240-630: The position of seeking a financing partner for Acorn, but in a significantly more urgent timeframe, making "financial institutions or a large computer company" the most likely candidates, these having the necessary resources and decision-making agility for a timely intervention. The dire financial situation was brought to a head in February 1985, when one of Acorn's creditors issued a winding-up petition. It would eventually emerge that Acorn owed £31.1 million to various creditors including manufacturers AB Electronics and Wong's Electronics. Wong's had been awarded
8343-537: The production problem and in 1984, production reached its anticipated volumes, but the contracts Acorn had negotiated with its suppliers were not flexible enough to allow volumes to be reduced quickly in this unanticipated situation, and supplies of the Electron built up. At the time of the eventual financial rescue of Acorn in early 1985, it still had 100,000 unsold Electrons plus an inventory of components which had all been paid for and needed to be stored at additional expense. 40,000 BBC Micros also remained unsold. After
8446-475: 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. Customers were occasionally able to buy the computer as a bare bones system for self-assembly. After speculation on the usenet newsgroups , a website for the hardware was spotted in mid October 2002. Units first went on sale in December 2002. Prices started from £1249. Castle ceased production of
8549-508: The proprietary operating system offering "limited flexibility". Instead, Olivetti sought to promote its M19 personal computer for the European schools market, offering it to Acorn for sale in the UK (ultimately, as the rebadged Acorn M19 ). Olivetti would eventually offer both Acorn's Master Compact and the Thomson MO6 to the Italian market with its Prodest branding. Personal digital assistant A personal digital assistant ( PDA )
8652-535: The quality of the recognition. Touchscreen PDAs intended for business use, such as the BlackBerry and Palm Treo , usually also offer full keyboards and scroll wheels or thumbwheels to facilitate data entry and navigation. Many touchscreen PDAs support some form of external keyboard as well. Specialized folding keyboards, which offer a full-sized keyboard but collapse into a compact size for transport, were made available for many models. External keyboards may attach to
8755-429: The result of disagreement between Acorn and Lazards over the measures needed to rescue the company, with Lazards favouring a sale or refinancing whereby the founders would lose control, Acorn and their replacement advisors, Close Brothers, were reported to be pursuing a "radical reorganisation of the company". Lazards had sought to attract financing from GEC but had failed to do so. Close Brothers also found themselves in
8858-589: 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. Acorn Computers Acorn Computers Ltd. was a British computer company established in Cambridge , England in 1978 by Hermann Hauser , Chris Curry and Andy Hopper . The company produced
8961-512: The same time, Acorn also bought into Torus Systems - a company developing a "graphics-controlled local network called Icon" for the IBM PC platform - to broaden Acorn's networking expertise. Icon was a solution based on Ethernet, as opposed to the Acorn-related Econet and Cambridge Ring technologies, equipping appropriately specified IBM-compatible computers to participate on a network using
9064-420: The state of Acorn's finances intensified with the appointment of a temporary chief executive, Alexander Reid, to run the company, together with the announcement that Acorn had replaced its financial advisors, Lazards, and that the company's stockbrokers, Cazenove, had resigned, ultimately leading to the suspension of Acorn shares, these having fallen to a low of 23 pence per share. With these events reportedly being
9167-501: The supply of its ULA meant that Acorn was not able to capitalise on the 1983 Christmas selling period. A successful advertising campaign, including TV advertisements, had led to 300,000 orders, but the Malaysian suppliers were only able to supply 30,000 machines. The apparently strong demand for Electrons proved to be ephemeral: rather than wait, parents bought Commodore 64 or ZX Spectrum for their children's presents. Ferranti solved
9270-413: The suspension of Acorn's shares. Of subsequent significance, Hermann Hauser was also expected to announce a "VLSI chip design using a reduced instruction set". Unveiled towards the end of 1985, the Communicator was Acorn's answer to ICL's One Per Desk initiative. This Acorn machine was based around a 16-bit 65SC816 CPU, 128 KB RAM, expandable to 512 KB, plus additional battery-backed RAM. It had
9373-543: The system by putting the CPU card from the System 1 in a 19-inch (480 mm) Eurocard rack that allowed a number of optional additions. The System 2 typically shipped with keyboard controller, external keyboard, a text display interface, and a cassette operating system with built-in BASIC interpreter . The System 3 moved on by adding floppy disk support, and the System 4 by including
9476-462: The system for themselves. This system was used with a BBC Micro and a PC compatible version was also planned. Advertising was aimed at those with technical expertise, rather than consumers and the education market, with a number of technical specifications listed in the main text of the adverts. Wilson subsequently coded BBC BASIC in ARM assembly language, and the in-depth knowledge obtained from designing
9579-432: The use of these devices to scan product or item codes. Typical applications include: PDAs and handheld devices were allowed in many classrooms for digital note-taking. Students could spell-check, modify, and amend their class notes on a PDA. Some educators distributed course material through the Internet or infrared file-sharing functions of the PDA. Textbook publishers released e-books , which can be uploaded directly to
9682-1053: Was a subsidiary of Datum, the Mexican manufacturer of the Spanish version of the BBC Microcomputer (with modified Spanish keyboards for the South American market). The sales office in Woburn, Massachusetts was closed at this time. Acorn was reported as having achieved "negligible U.S. sales". In 1990, in contrast, Acorn set up a sales and marketing operation in Australia and New Zealand by seeking to acquire long-time distributor Barson Computers Australasia, with Acorn managing director Sam Wauchope noting Acorn's presence in Australia since 1983 and being "the only computer manufacturer whose products are recommended by all Australian state education authorities". Acorn also sought once again to expand into Germany in
9785-501: Was aimed at the enthusiast market much like the BBC Micro, its real area of success was business. The successor to the PC, the XT (eXtended Technology) was introduced in early 1983. The success of these machines and the variety of Z80 -based CP/M machines in the business sector demonstrated that it was a viable market, especially given that sector's ability to cope with premium prices. The development of
9888-587: Was also spending a large portion of its reserves on development: the BBC Master was being developed; the ARM project was underway; the Acorn Business Computer entailed a lot of development work but delivered few products, with only the 32016-based model ever being sold (as the Cambridge Workstation). The company's research and development staff had grown from around 100 in 1983 to around 150 in 1984,
9991-559: Was an important addition to the learning ecology rather than a replacement. Software companies also developed PDA programs to meet the instructional needs of educational institutions, such as dictionaries, thesauri , word processing software, encyclopedias, webinars and digital lesson planners. PDAs were used by music enthusiasts to play a variety of music file formats. Many PDAs include the functionality of an MP3 player. Road rally enthusiasts can use PDAs to calculate distance, speed, and time. This information may be used for navigation, or
10094-538: Was launched in January 1979 as the first product of Acorn Computer Ltd. , a trading name used by CPU to keep the risks of the two different lines of business separate. The microcomputer kit was named as Acorn System 75. Acorn was chosen because the microcomputer system was to be expandable and growth-oriented. It also had the attraction of appearing before " Apple Computer " in a telephone directory. Around this time, CPU and Andy Hopper set up Orbis Ltd. to commercialise
10197-486: Was low enough, at around £80 (equivalent to £420 in 2023), to appeal to the more serious enthusiast as well. It was a very small machine built on two cards, one with an LED display, keypad, and cassette interface (the circuitry to the left of the keypad), and the other with the rest of the computer (including the CPU ). Almost all CPU signals were accessible via a Eurocard connector. The System 2 made it easier to expand
10300-460: Was owned by the National Enterprise Board , a government agency operating in close collaboration with the DoI. The choice was also somewhat ironic given that the NewBrain started life as a Sinclair Radionics project, and it was Sinclair's preference for developing it over Science of Cambridge's MK14 that led to Curry leaving SoC to found CPU with Hauser. The NEB moved the NewBrain to Newbury after Sinclair left Radionics and went to SoC. In 1980–1982,
10403-481: Was responsible for development work. At some point, Curry had a disagreement with Sinclair and formally left Science of Cambridge, but did not join the other Acorn employees at Market Hill until a little while later. The Acorn Microcomputer, later renamed the Acorn System 1 , was designed by Sophie Wilson (then Roger Wilson). It was a semi-professional system aimed at engineering and laboratory users, but its price
10506-447: Was responsible for development, production and marketing of software for Acorn's computer range. Vector Marketing Limited was established to handle distribution-related logistics and the increasing customer support burden. As part of Acorn's office automation aspirations, conducting "advanced software research and development", Acorn Research Center Incorporated was established in Palo Alto, California. Acorn Leasing Limited rounded out
10609-480: 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
