Atari 800XL User Manual

When you turn on
your ATARI 800XL, it
automatically tests itself.
You also have the option
of double checking the
computer's memory,
sound and colors, and
keyboard.
Thereafter, run the
test only occasionally,
because the computer
tests its memory each
time it's turned on. If the
circuits fail the test, the
words MEMORY TEST
and red and green
squares and rectangles
appear on the screen.
The built-in ATARI BASIC
and any software that you
try to use will be ignored
by the computer.
This means that your
computer needs service.
Contact your ATARI
Home Computer retailer
or factory-authorized
ATARI SERVICEsM center.
II'he Self Tests
Start the tests by holding
down OPTION while turn-
ing on the computer or
by typing BYE when
BASIC says READY. A
SELF-TEST menu will ap-
pear on the screen. Like
a restaurant menu, this
..
.. .. ..
offers a choice of selec-
tions: ALL TESTS, MEM-
ORY TEST, AUDIO-VISUAL
TEST, AND KEYBOARD
TEST. Press SELECT
to choose a test, then
press START. Press HELP
to return to the SELF-
TEST menu.
When you select ALL
TESTS, the computer
runs the tests for you.
They repeat until you
press HELP. Press RESET
to stop the tests and
return to ATARI BASIC .
