ent for each program, so read the instructions
that come with your program
to
find out what
these keys do, if anything.
,A,nd then there's the SYSTEM RESET key. Sounds
powerful, doesn 't it? That's because it is. When
you press SYSTEM RESET, it turns the machine off
and back on again. If you are working with
some kinds of software, the program will be
interrupted and you will have to begin again.
Use this key with care . Follow any specific in-
structions that come with your software.
Since you aren 't running a program now and
don 't have anything in your computer's working
memory that you need
to
keep, you won 't lose
anything if you reset the system now. Press the
SYSTEM RESET key, and you 'll go back
to
the
READY message.
On the 1200XL computer there is a HELP key.
Atari intends
to
release software packages that
will let you push this key to get helpful informa-
tion about how
to
use the software.
The HELP, SELECT, START, and RESET keys are
also used during the system self-tests on the
1200XL. If you have no cartridge or other soft-
ware in your computer, you can run the self-
tests when you turn on the computer and the
word ATARI appears. The self-tests determine if
the memory, sound and color, and keyboard are
operating properly.
