The Acorn Network Computer was a network computer (a type of thin client [1] ) designed and manufactured by Acorn Computers Ltd. It was the implementation of the Network Computer Reference Profile that Oracle Corporation commissioned Acorn to specify for network computers (for more detail on the history, see Acorn's Network Computer). Sophie Wilson of Acorn led the effort. It was launched in August 1996.
The NCOS operating system used in this first implementation was based on RISC OS and ran on ARM hardware. [2] [3] Manufacturing obligations were achieved through a contract with Fujitsu subsidiary D2D. [4]
In 1997, Acorn offered its designs at no cost to licensees of RISC OS. [5]
The NetStation was available in two versions, one with a modem for home use via a television, and a version with an Ethernet card for use in businesses and schools with VGA monitors and an on-site BSD Unix fileserver based on RiscBSD, an early ARM port of NetBSD. Both versions were upgradable, as the modem and Ethernet cards were replaceable "podules" (Acorn-format Eurocards). The home version was trialled in 1997/98 in conjunction with BT. [6]
The Home NC and Corporate NC both used the ARM 7500FE and supported PAL, NTSC and SVGA displays. They had identical specifications. [7] [8] The Office NC used a StrongARM SA-110 200 MHz processor. [9] The ARM7500-based DeskLite was launched in 1998. [10]
Acorn continued to produce ARM-based designs, demonstrating its first StrongARM prototype in May 1996, [11] and the Office NC 6 months later. [12] This evolved into the CoNCord, launched in late 1997. [13] [14]
Further designs included the Set-top Box NC (STB NC), the ExecPhone NC, and the NC TV. [12] [15]
The second generation Network Computer operating system was no longer based on RISC OS. NC Desktop, from Oracle subsidiary Network Computer Inc., instead combined NetBSD and the X Window System, featuring desktop windows whose contents were typically described using HTML, reminiscent of (but not entirely equivalent to) the use of Display PostScript in NeXTStep. The product ran on ARM, StrongARM and x86 architectures and could be run on traditional personal computers. [16] NC Desktop was the recommended software solution for products based on the StrongARM-based Digital Network Appliance Reference Design (DNARD). [17] Later NCs were produced based on the Intel Pentium architecture such as products from Accton Technology Corporation [18] and UMAX Data Systems. [19]
The NetStation was planned to ship with a smart card to enable internet banking. [20]
The history of the graphical user interface, understood as the use of graphic icons and a pointing device to control a computer, covers a five-decade span of incremental refinements, built on some constant core principles. Several vendors have created their own windowing systems based on independent code, but with basic elements in common that define the WIMP "window, icon, menu and pointing device" paradigm.
MIPS Tech LLC, formerly MIPS Computer Systems, Inc. and MIPS Technologies, Inc., is an American fabless semiconductor design company that is most widely known for developing the MIPS architecture and a series of RISC CPU chips based on it. MIPS provides processor architectures and cores for digital home, networking, embedded, Internet of things and mobile applications.
Acorn Computers Ltd. was a British computer company established in Cambridge, England, in 1978. The company produced a number of computers which were especially popular in the UK, including the Acorn Electron and the Acorn Archimedes. Acorn's BBC Micro computer dominated the UK educational computer market during the 1980s.
ARM is a family of RISC instruction set architectures (ISAs) for computer processors. Arm Ltd. develops the ISAs and licenses them to other companies, who build the physical devices that use the instruction set. It also designs and licenses cores that implement these ISAs.
Risc PC was a range of personal computers launched in 1994 by Acorn and replaced the preceding Archimedes series. The machines had a unique architecture unrelated to IBM PC clones and were notable for using the Acorn developed ARM CPU which is now widely used in mobile devices.
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.
The Network Computer was a diskless desktop computer device made by Oracle Corporation from about 1996 to 2000. The devices were designed and manufactured by an alliance, which included Sun Microsystems, IBM, and others. The devices were designed with minimum specifications, based on the Network Computer Reference Profile. The brand was also employed as a marketing term to try to popularize this design of computer within enterprise and among consumers.
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.
QEMU is a free and open-source emulator. It emulates a computer's processor through dynamic binary translation and provides a set of different hardware and device models for the machine, enabling it to run a variety of guest operating systems. It can interoperate with Kernel-based Virtual Machine (KVM) to run virtual machines at near-native speed. QEMU can also do emulation for user-level processes, allowing applications compiled for one processor architecture to run on another.
The Acorn Online Media Set Top Box was produced by the Online Media division of Acorn Computers Ltd for the Cambridge Cable and Online Media Video on Demand trial and launched early 1996. Part of this trial involved a home-shopping system in partnership with Parcelforce.
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.
Network Computer Reference Profile was a specification for a network computer put forward by Oracle Corporation, endorsed by Sun Microsystems, IBM, Apple Computer, and Netscape, and finalized in 1996.
The A7000 and A7000+ were Acorn Computers' entry level computers based somewhat on the Risc PC architecture.
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.
NCOS is the graphical user interface-based operating system developed for use in Oracle Corporation's Network Computers, which are discontinued. It was adapted by Acorn Computers from its own RISC OS, which was originally developed for their range of Archimedes desktop computers. It shares with RISC OS the same 4 MB ROM size and suitability for use with TV displays.
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.
VirtualAcorn is the brand name of several commercial emulators of Acorn Computers computer hardware platforms.
Galileo was an unreleased 32-bit operating system that was under development by Acorn Computers as a long-term project to produce "an ultra-modern scalable, portable, multi-tasking, multi-threading, object-oriented, microkernel operating system", reportedly significant enough to Acorn's strategy to warrant a statement to the financial markets.
[Ellison's] proposed Network Computer needed things Acorn already possessed in spades: a cheap, powerful processor in the form of the ARM 7500; a compact ROM-based operating system, RISCOS; TV compatibility.
A scaled down version of RISC OS was licensed to Oracle to form its NCOS(TM).
In England, Acorn has contracted with D2D, a division of Fujitsu/ICL to manufacture the Acorn NC.
Acorn Group has decided to offer its Network Computer hardware production and reference designs at no cost to licensees of its information appliance operating system, RISC OS.
