Archimedes 540: 

IMAGE OF THE FUTURE 



The Archimedes 540 is built for performance. 


No matter how demanding your applications are for 
memory and speed the Archimedes 540 will give you the 
professional edge. The combination of fast, fully 
addressable and expandable RAM, with the excellent 
onfooard video display capabilities makes the 
Archimedes 540 the ideal machine for desktop 
publishing, complex spreadsheets and CADCAM _ 
as well as image analysis and multi-media I 

training. Even the most processor-intensive and % 
memory demanding applications can be run in a ^ 
multi-tasking environment. 


central processor (ARM-3) operates faster ' 
than a 25MHz 486 processor, t 4K of cache 
memory built into the processor chip provides 
further performance gains by reducing the need to 
fetch instructions and data from the 


new 


mam memory 


The machine is supplied with 4 Mbytes of high 
performance RAM as standard and plug-in 
upgrades to 8, 12 and 16 Mbytes are available. 
This allows the professional user to run several 
memory intensive applications simultaneously 
without compromising speed or efficiency.

The internal 100 Mbyte SCSI hard disc gives fast 
access and rapid data transfer. You can 

maintain a vast bank of data and 

keep a whole library of software 
available for

Leading the 

ARCHIMEDES RANGE 


The Archimedes 540 leads the Archimedes range 
of high-performance computer systems. 

Each machine in the range is based around the 
Acorn RISC Operating System - RISC OS - 
which gives you the most straightforward way 
of controlling computing tasks. Directing your 
Archimedes system with the windows, icon, 
mouse and pointer interface is easy to learn 
because it is intuitive, and exceptionally 
productive. 

The Archimedes 540 maximises the potential 
of the RISC OS multi-tasking system, enabling 
you to run more than one application at a time 
and to transfer data quickly between 
applications.

APPLICATIONS 


Archimedes computers are helping to break new frontiers in research. 


In healthcare, image analysis is speeding up monitoring for spinal deformities and improving the chances 
of identifying abnormalities in their early stages. The power of the Archimedes system is also proving 
invaluable in the analysis of visual pigments in patients with retinal disorders, enabling researchers to 
compensate for the difficulties caused by constant eye movements by producing average images. 


The Archimedes system is currently being used in X-ray astronomy, an area of research 
that will benefit immediately from the introduction of the new TCP/IP suite, as huge 
amounts of data need to be transferred onto mini and mainframe computers. 


Archimedes computers are also redefining expectations from multi-media 
training, providing the ideal environment for the development of cost-effective 
computer-based training and desktop simulation. 









































Expansion 



With the huge range of add-ons and 
peripherals available, you can customise your 
Archimedes 540 to meet your specific 
requirements. In addition to the plug-in RAM 
options, expansion cards are available to 
configure your ideal system. Expansion options 
include: 

■ I/O Expansion Card for specialised 
communication and control functions, such as 
scientific instrumentation, or non-keyboard 
input systems. 

■ ROM Expansion Card for specialised 
system development. 

■ The Floating Point Accelerator (FPA), 
being developed as a fifth member of Acorn’s 
RISC chipset, will offer increased speed for 
highly intensive mathematical computations. 
This new floating point solution will be 
available in 1991. 

■ MIDI Expansion Card providing standard 
control interface for electronic musical 
instruments. 

■ High performance video output with 

genlock for video overlays 
■ High resolution frame stores 



■ Direct laser printer cards 
which give high quality 
and high speed print 
capability for DTP. 

■ Real time colour digitisers for 
\ video image capture 

. IEEE 488 
■ STE Bus 


■ Ethernet 
and Econet 
cards 



In one example, simulations of helicopter operations incorporate.real-time colour animation to simulate 
real equipment and processes. This is combined with built-in digital audio for high fidelity reproduction 
of sound effects which simulate verbal procedures. 

Of course, you can also run the full range of software packages designed for the Archimedes family. There 
is already a wealth of software available, from word processors to databases, from 3D modelling to 
multi-media environments. 

In addition, the PC emulator software transforms your machine into a PC at a click of the mouse. 
MS-DOS can be loaded from your hard disc, giving you access to the wide range of standard business 
software developed for IBM compatible machines. You can store your MS-DOS applications on the hard 
disc for fast access, along with your files and data, or alternatively on standard IBM format floppy discs. 
The power of the new ARM-3 processor gives the speed of an AT class PC machinef for MS-DOS 
applications.

Meeting 

INDUSTRY 

STANDARDS 


The Archimedes 540 embraces a whole spectrum 
of industry standards. 


With the Ethernet expansion card, you can 
link your Archimedes 540 to the rest of your 
computer system using industry standard 


networking technology. The optional TCP/IP 


Protocol Suite software enables you to connect 
your Archimedes 540 straight into a UNIX 
environment. This enables you to add the 
power and flexibility of the Archimedes 540 to 
your LAN, integrating with other TCP/IP' 
based systems in a window on the RISC OS 
desktop. For local departmental connectivity 
of work groups any Archimedes computer can 
act as a gateway between Econet, Acorn’s low 
cost proprietary network, and Ethernet 
subnetworks.

SuperVGA monitors and very high resolution 
monochrome monitors. You can upgrade or 
change your monitor with no requirement to 


add graphics expansion boards. This gives you 
the benefits of a supercrisp, rock steady display 
and enables you to select the most appropriate 
monitor from the most economical to the 


highest specification. 


The built'in SCSI interface supports direct 
access to up to six external peripherals such as 
large capacity disk drives, tape streamers, CD 
ROMS, optical drives, DAT drives and 


scanners.
