Atari 520ST User Manual

INTRODUCTION
A few
years ago the
speed, memory, and
graphics power
of the
ATARI® 520ST™
Computer
were beyond the
dreams of most
computer
enthusiasts. Even
today, we
know of no other
computer
that can offer
you
the performance
of the
520ST Computer
at any
price.
The
ATARI
520ST System
combines
advanced technology
and
graphic
sensibility in
an
easy-to-understand and
simple-to-use
working
environment.
No more
obscure
commands
to memorize
and
no more
complicated
procedures
to
follow.
Computer
opera-
tions are
represented
by icons
on the screen
—
you simply
choose
what
you
want,
point
to
the icon,
and click!
With over
524,000 bytes of
Random
Access Memory,
the
520ST
Computer
has
the
capacity for
the
most complex
word
processing
tasks or the
most
detailed
spreadsheet
procedures.
Educational
programs
take on new
potential
when they are
written
to take
advantage
of the
graphics
and
speed of the
ST
Computer.
The
520ST Computer
offers you all the
computing
capability
you
need:
512 different
colors, three
graphics modes,
80 columns of
text, and
enhanced
graphics resolution. And with
the potential
to
add
a
hard
disk,
a modem,
a
printer, and even
a music
synthesizer,
the ST
Computer
System can grow with
your
needs
and
adapt to new
uses.
