Ram Test - Atari 130XE Service Manual

RAM TEST

If no errors occur, the test will take about 15 seconds. When the test is done, PASS or
FAIL will be displayed. Press the space bar to continue.
If an error does occur, the test will halt, and the test number (1-4), the address which
failed, the data read from that address, the data expected, and the bits that failed (i.e.
numbers 1-8, corresponding to 8 ram chips, printed red if data was bad, green if good) will
be displayed to the screen, as in the following example:
1 (test number)
7E45=34 35 (address, data read, data expected)
1 2 3 4 5 6 7 8 (bit numbers)
