Checking It Out When you turn on your ATARI 130XE, it automatically tests itself. But you can run three separate tests just to insure that your computer is working properly. Running all three tests after setting up your com- puter for the first time is recommended. To run the tests, turn the computer on while you a re holding down the ~ key. You may also get to the test program by typing BYE when ATARI BASIC gives the Ready prompt. (If you have a disk drive hooked up to your com- puter, make sure it is turned off when you run the Self Test.) A Self-Test menu will appear on the screen . Like a restaurant menu, this menu offers a choice of selections:
MEMORY TEST , AUDIO- VISUAL TEST, KEYBOARD TEST , and ALL TESTS. Press I Select 1 to choose a test, then press I Start I. Press I Help I at any time to return to the Self-Test menu . When you select ALL TESTS, the computer runs all three tests for you. The tests repeat until you press the ~ key. Press I Reset I to stop the tests and return to ATARI BASIC.
