  Acorn Archimedes - Wikipedia, the free encyclopedia
Unlike the previous Archimedes models, the A3000 came in a single-part case similar to the Amiga 500 and Atari ST computers, with the keyboard attached to the main unit.
The Archimedes was one of the most powerful home computers available during the late 1980s and early 1990s; its main CPU was faster than the stock 68000s found in the more popular Atari ST and Commodore Amiga machines.
The success of the Archimedes in British schools was due partly to the Computers for Schools scheme organised by the Tesco supermarket chain in association with Acorn, and most students/pupils in the aforementioned countries in the early 90s will have seen/used an Archimedes.

 Acorn Computers - Wikipedia, the free encyclopedia
Acorn's BBC Micro computer dominated the UK educational computer market during the 1980s and early 1990s, drawing many comparisons with Apple in the U.S. Though the company was broken up into several independent operations in 2000, it leaves an impressive legacy, particularly in the development of RISC personal computers.
Even from the time of the Atom, Acorn were considering how to move on from the 6502 processor: the 16-bit Acorn Communicator developed in 1982 using the 65816 being a key example.
Acorn was in real trouble: by the end of the year it had 250,000 unsold Electrons on its hands, which had all been paid for and needed to be stored – at additional expense.

Initially, the Archimedes was launched in 4 different versions: BBC 305, BBC 310, 410 and 440.
They were a new generation of computer as Acorn went from the 8 bit 6502 processor, skipped 16 bits, and went direct to the in-house developed 32 bit ARM processor (32 bit data bus, 26 bit address bus and 16 registers).
The 410/1, 420/1 and 440/1 were the second generation of Archimedes machines.

 Acorn Archimedes
The Acorn Archimedes was Acorn, Ltd 's first general purpose home computer based on their own ARM RISC CPU, and spawned a family of very capable machines with various options.
The Archimedes was in fact the most powerful home computer during the late 1980s; it could run a piece of software faster and with better visual quality than the more-famous and better selling Atari ST and Commodore Amiga.
This was mainly because the ARM CPUs were not untypically three times faster than the competition (the Motorola 68000 family), and thus was able to control and respond to the graphics hardware in a much faster manner.

 The Acorn Archimedes computer   (Site not responding. Last check: 2007-11-06)
Acorn's Archimedes computer has received a lot of publicity lately -- indeed Acorn is rumoured to have got rid of half its staff by way of celebration -- so we decided to give the machine a test drive.
The Archimedes is clearly a pioneering machine with a far greater arithmetical ability than its predecessors the Pythagoras and the Plato.
For instance, it is able to calculate pi more accurately than ever before (showing that it lies between 22/7 and 223/71), and has a far greater understanding of large numbers (for example, it gave us a pretty good estimate of the number of grains of sand on the beach).

Dave Walker The Acorn Archimedes 400/1 series and the older pre June 1989 440 systems both had a Hard Disc interface designed and built on the PCB (Printed Circuit Board).
Acorn Archimedes 400/1 Series Approximately half way up the left hand side of the PCB (facing from front to rear of the machine, the backplane will need to be removed before a clear view of the sockets will be seen) are three sockets labelled SK8, SK10, SK11.

 Real World Technologies - ARM’s Race to Embedded World Domination
It started out as the Acorn RISC Machine, named after a British company, Acorn Computers Ltd. In the early 1980’s Acorn was looking to replace the 6502 processor in its line of personal computers, which was rapidly running out of steam (not to mention address space).
Acorn briefly considered the Motorola 68000 but rejected on the ground that its inclusion of long running uninterruptible instructions, like divide DIVS, would have more than doubled its interrupt latency compared to the 6502.
A group of Acorn engineers, including Robert Heaton, Stephen Furber, and Jamie Urquhart, created a behavioral model of the new processor architecture, and worked on the design of the register file, data path, and control circuitry.

Archimedes A family of microcomputers produced by Acorn Computers, Cambridge, UK.
The Archimedes, launched in June 1987, was the first RISC based personal computer (predating Apple Computer's Power Mac by some seven years).
The Archimedes was designed as the successor to Acorn's sucessful BBC Microcomputer series and includes some backward compatibility and a 6502 emulator.

When Arthur was originally released it contained a large number of bugs - one report at the time noted that an Archimedes had been seen sporting a sticker with a warning that the operating system could randomly delete files of its own accord.
Acorn pumped money and resources in to developing and improving Arthur, and by the end of 1988 there had been at least three major releases.
When the Archimedes was launched, the A305 cost £800 to £1000, the A310 cost £950 to £1200 and the A440 cost £2900 to £3150, depending on the type of monitor supplied.

The Acorn Archimedes series of 32 bit RISC personal computers was British company Acorn's answer to the Atari ST and Amiga.
Acorn had started development of it's own RISC processor in 1983 called the ARM (Acorn Risc Machine, later changed to Advanced RISC Machine) which it eventually used for the first time in this computer.
The initial release of the Acorn was 2-3 times faster than the then current ST's and Amiga's, and even came with an emulator for Acorn's older BBC computers (something Atari and Commodore never did).

 About Acorn computers and ARM processors
The Acorn platform is probably one of the smallest computer platforms, consisting of some estimated 500,000 machines (excluding older 8-bit computers).
Acorn Archimedes computers were the first of Acorn's computers to use a 32 bit architecture.
Acorn also introduced the A7000 (followed later by the A7000+), a cut-down version of the RiscPC with only one processor card slot, only one SIMM slot, VRAM soldered to the motherboard and a lower price.

The Acorn Archimedes A3000 was based on the Archimedes A410 but in an 1040ST/Amiga A500-style wedge unit, designed for the home market, it was intended as a replacement for the BBC Micro and like the earlier Archimedes models it was only really used in British schools up until very recently.
Acorn started to phase out the Archimedes name and the machine is now simply badged Acorn A3000.
Rumours have it that some of the Acorn A410 models had serious reliability problems and had to be recalled, so the Archimedes name was dropped to boost the machine's reputation.

Many North American computer enthusiasts first became aware of Acorn and ARM from a 1987 article about the Acorn Archimedes A310 PC in Byte Magazine [3].
The Archimedes was based on ARM2, a second generation of the original ARM design.
Despite the simpler and potentially much less expensive RISC processor and UMA system architecture, the Archimedes A310 was quite competitive in performance with 386-based PC’s as can be seen in Table 1 [4].

Meanwhile, the IBM Compatible PC was aligning itself as a contender with its increasing functionality as a multimedia computer, made possible by developments such as the Intel 486 processor and the Windows 3.0 operating system.
As the public became aware of the PC's endless expandability, and with the arrival of the World Wide Web and Windows 95, the fate of the Archimedes was sealed.
