5.4 Running Self-Tests
Self-test diagnostic programs reside permanently in your system’s read-only
memory (ROM). You can run self-tests from the console terminal. After
running each self-test, enter the command TEST 50 or T 50 and press Return
to display the status of the device tested.
To test a device in your system, follow these steps:
1.
Use Table 5–2 to find the number or letter that represents the device you
want to test.
2.
Put the system in console mode by pressing the halt button on the rear
of the system unit. Use a pen or a small pointed object to press the button.

the first and last numbers of the series:

The system displays the number of each device as it is tested, followed by a
series of periods.
