Procedure #5: Self Test
A. Read the introduction in The Self Test User's Guide that came with your computer to get an overall
idea of the test, the terminal display, and the front panel Status Display.
B. Now look over the Self Test Checker below. These codes are taken from the full list of normal and
error codes given in The Self Test User's Guide.
The error codes to watch for on the front panel Status Display are listed in the Blinking column. If
an error occurs, the self test blinks the code for it. The code for the beginning of each subtest is
given in the Steady column. Steady means normal condition.
The special symbols used in the Self Test Checker have these meanings:
•
The slash character (/) means the codes blink alternately, showing the type of error and its
location.
•
The letter X in the items with an asterisk (*) means a digit (1-9) will display. Record the
digit you see on the screen.
•
The ranges 1-16 and 1-2 in the items with an asterisk (*) mean a number in the given
range will display on the screen. Record the number that appears.
C. Turn the computer off. Perform Section C of "Procedure #3: Power-up/Reset".
D. Start the self test: hold down the Reset button on the front panel while you turn on the power by
pressing the power button on. This enables the self test. Release the Reset button.
E.
Let the self test know your terminal's baud rate.
The terminal you use for the self test must be plugged into one of the four serial I/O ports on the
CPU board.
The numbers 80 and 82 mark the beginning of the test; they appear on the display for only a fraction
of a second, followed by a steady 5b. When you see a steady 5b, press your keyboard's space bar
several times. This tells the self test your terminal's baud rate so it can display messages at the
correct baud rate.
F.
Note which of the tests apply to your computer.
On the screen, the self test displays an inventory of your computer's configuration to let you know it
will test only the components it has detected. You may want to check these off on the Self Test
Checker, shown in the table below.
G. Observe the front panel Status Display and the screen.
If a blinking error code appears on the front panel Status Display, note it on the Self Test Checker.
As each test finishes, note whether the component being tested passed or failed.
If an error occurs during the Memory Test, the addresses of the errors display on the screen. Jot
them down on the Self Test Checker.
H. Stop the self test at an appropriate time.
