Subject: News Release: Acorn A4 Portable
Date: 1 Jul 92 07:50:38 GMT
Announcing Acorn's A4 Portable - "... a quart in a pint pot"
Acorn Computers has announced the launch of its first portable
notebook computer - the Acorn A4.
The A4 - so called because its footprint is exactly the size of an
A4 sheet of paper - utilises an ARM 32-bit RISC processor that has
recently won for Acorn the 1992 Queen's Award for Technology.
The A4 will be available in two versions - a base model with 2MB of
RAM as standard and with a 2MB floppy disc drive, and a 4MB model
that includes a 60MB IDE hard disc.
In terms of product positioning, the Acorn A4 (which runs at 12mips)
is as powerful as Apple's top-of-the-range PowerBook 170 - but at
only half its price, and is equivalent in performance to a 486-based
PC but at a 386sx price.
The A4 runs Acorn's latest proprietary operating system - RISC OS3 -
ensuring compatibility with Acorn's large installed base of RISC
computers which has grown exponentially since 1987. RISC OS is a
fully multitasking operating system with an integral window GUI
supplied as standard.
But in addition, because of the ARM 3 chip's processing power, DOS
programs can be run at the same time and within the same
multitasking environment as RISC OS programs. This fact alone allows
the easy interchange of text and graphics between DOS-based
programs and RISC OS applications.
Unlike conventional PCs, the Acorn A4 has its operating system in
ROM, as well as eight commonly used applications (including a
versatile text editor and a drawing package) which means that no
disc space is used for their storage and that they are all instantly
available.
Acorn's Marketing Director, Mike O'Riordan, said he envisaged strong
demand from both the Educational and Consumer sectors. "What is
particularly impressive is that the A4 boasts the full power of our
highly successful A5000 computer, yet everything is packed into only
a fraction of the volume. It really is a quart packed into a pint
pot!
"Acorn is already the number one supplier into Education and the
launch of our portable will further enhance our range within this
key market area.
"The Consumer Market, on the other hand will welcome the benefits of
RISC technology and the ease of use that it provides the end user in
terms of a simple, yet powerful, working environment that leaves the
likes of Windows 3 standing!
Bob Coates, Acorn's General Manager for Market Development, picked
up the theme. "We see the A4 as having particular appeal to parents,
small businesses and professionals alike who will immediately
appreciate the benefits of our established current range of
computers, but now in a portable format."
Acorn's General Manager of Education, Peter Talbot, said "Quite
simply, this has to be a major consideration for schools planning
their IT purchasing requirements. The A4 will find a place as a
departmental resource, for project work both within the school
environment as well as in the field, for specialist subject areas
and even for those with special needs.
"It will also be purchased by lecturers, teachers and students alike
as a personal productivity tool which can easily be carried around
between the home and educational environment."
The cost of the entry level A4 is #1,399 ex VAT with a special price
for educational establishments of #1,099. The higher level 4MB RAM
with 60MB hard disc version costs #1,699 or #1,399 for education.
Volume shipment of the two models together with their complete range
of supporting peripherals is planned for September onwards.
