| known_for = Work with Acorn Computers, particularly the BBC Micro and on the ARM processor

Originally conceived by Acorn Computers for use in its personal computers, the first ARM-based products were the co-processor modules for the BBC Micro series of computers.

After achieving success with the BBC Micro computer, Acorn Computers Ltd considered how to move on from the relatively simple MOS Technology 6502 processor to address business markets like the one that would soon be dominated by the IBM PC, launched in 1981.

* 1998 – Castle Technology acquire the rights to continue to market and produce the RiscPC during the breakup of Acorn Computers.

A British computer that used the 6502 was the BBC Micro, manufactured by Acorn, Ltd.

The work was so important that Acorn spun off the design team in 1990 into a new company called Advanced RISC Machines Ltd. Advanced RISC Machines became ARM Ltd when its parent company, ARM Holdings plc, floated on the London Stock Exchange and NASDAQ in 1998.

The Acorn Atom was a home computer made by Acorn Computers Ltd from 1980 to 1982 when it was replaced by the BBC Micro ( originally Proton ) and later the Acorn Electron.

In March 1999 RISCOS Ltd negotiated a license with Element 14, the recently renamed Acorn Computers, and set about finishing the development of RISC OS 4.

ARX was a Mach-like operating system written in Modula-2 + developed by Acorn Computers Ltd in the Acorn Research Centre ( ARC ) UK and later Olivetti Research Center and later on Software Technology Laboratory ( when Olivetti bought out Acorn ) at Palo Alto for their new ARM RISC processors based Archimedes computers range.

First implemented by Thomas Harte's ElectrEm emulator and related tools, it is now supported by major emulators of Acorn machines and carried by two online archives of Acorn software numbering thousands of titles.

The INF convention, described and implemented by Wouter Scholten in bbcim ( 1995 ), extends the output format of the command ( Acorn DFS, ADFS ) to cover CRCs and the order of files on tape.

There are some modal variables affecting the interpretation of these chunks: the baud rate, 1200 baud for Acorn signals or 300 baud for KCS ; the exact carrier frequency, which determines the playing time of the reconstructed tape ; and the phase of the signal.

( via their ARA / ARA2 / ASR products ) allowed ' Sideways ROM ' capability, that allowed the standard Acorn ROM space to be programmatically mapped out for alternative EPROMs, either physically via ZIF Sockets, or ' virtually ' via ROM-images loaded into ( Battery-backed ) RAM in the same ROM memory space.

The 6809E was used in the TRS-80 Color Computer ( CoCo ), the Acorn System 2, 3 and 4 computers ( as an optional alternative to their standard 6502 ), the Fujitsu FM-7, the Welsh-made Dragon 32 / 64 home computers, and the SWTPC, Gimix, Smoke Signal Broadcasting, etc.

Acorn then seriously considered designing its own processor, and their engineers came across papers on the Berkeley RISC project.

In 1994, Acorn used the ARM 610 as the main central processing unit ( CPU ) in their Risc PC computers.

The Acorn Archimedes was Acorn Computers ' first general purpose home computer to be based on their own ARM architecture.

Some ( such as Apple, Atari, and Acorn ) persevered with their independent and quite different systems.

York Acorn Rugby League Club, who play in the National Conference League Premier Division, have their home ground at Thanet Road in Acomb.

Although Chip ' n ' Dale are almost always united in a common goal, this was one of their only shorts to see them working against each other, for the affections of Clarice, a performer at the Acorn Club.

The OS was originally developed by Acorn Computers for use with their 1987 range of Archimedes personal computers using the Acorn RISC Machine processors.

By May 1998 Acorn started to offer their ' Registered Developer ' scheme members the chance to pre-order a pre-launch prototype for testing and development, these were offered at a £ 950 ( ex VAT ) a significant discount on the public price of £ 1500 ( ex VAT ) revealed in June ..

During the years following the release of the Risc PC, Acorn had discussed using an alternative to RISC OS as their next operating system, using TAOS or writing their own microkernel-based operating system Galileo.

Others such as Al Purdy, Milton Acorn, and Earle Birney, already published, produced some of their best work during this period.

Acorn woodpeckers, as their name implies, depend heavily on acorns for food.

An early implementation of the taskbar concept is seen in Acorn Computers 1987 Arthur operating system, for their Acorn Archimedes computer.

Sonic and Sally are approved for marriage by King and Queen Acorn, but when Sonic refuses to rule by Sally's side while her parents are touring Mobius in favor of continuing to fight in the war, their relationship comes to an abrupt end.
