Atari 800

.
Play
with
the
keyboard
for a few
minutes.
There
is
no
way
you
can
damage
your
ATARI
800
by typing,
and
you
will
quickly
become
familiar
with
the
various
key
functions.
Each
key
will repeat
its
function
rapidly
if
you
depress
it for longer
than
one
second.
Type lower case
letters,
numbers,
some
punctua-
tion
marks, and math
symbols,
.iust
as
you
would on
a typewriter,
by
pushing
single
keys.

THE ATARI BOO
KEYBOARD
The ATARI
800 Keyboard
puts
a versatile set
of
printing
characters
and display
control functions
at
your
f ingertips.
Many special-purpose
application
cartridges and
some
games
will require
you
to type
your
responses or commands
to
the ATARI
800
Computer
using these
keys. Most
keystrokes
pro-
duce a
visable change on
the
i display screen.
However, there
are a
few keys
which are only used
in combination
with others.
To investigate the
ef-
fects of
each
key,
power
up
your
ATARI
800
without a cartridge
in either of
the cartridge
slots.
You will see the
display
pictured
below.
Notice the
square
below the
P in
Please. This
square
is called the
CURSOR.
A
cursor
is a
mark
which indicates
where the
next character
you
type
will appear
on the
screen.
The ability to
move the
cursor to
any
position
on the screen
and
change the
characters
being
displayed
is one of
ATARI
800's
most usef ul
features.
A
glance
at the
keytops
on
your
ATARI
800 tells
you
that
its
keyboard closely
resembles an ordinary
typewriter.
