Self-Test Super Sprint
Color Bar Test
The Color Bar Test screen is shown in Figure 3-15. This
test indicates the condition of the color RAM, video am¬
plifiers, and associated circuitry.
Sixteen vertical grey-scale bars and three groups of six¬
teen vertical bars with shades of red, green, or blue are
displayed. The brightest bar should be on the left and
darkest (black) bar on the right, with a black frame around
the screen. Each group of red, green, or blue should be
split in half horizontally to show two fade scales. Each
upper fade scale is ranged by changes in overall intensity
(Z) and each lower fade scale by individual color intensity
(R, G, B). This test helps to determine if white tracking is
set properly (grey-scale bars range from white to grey).
Refer to the white tracking procedure in the video display
manual if adjustment is required.
Press the red start button to obtain the next screen.
Color Purity Test
The Color Purity Test consists of five color displays that
indicate the condition of the display color-purity circuits.
The first display to appear should be a red screen with the
word RED displayed at the bottom of the screen as shown
in Figure 3-16.
Press the blue car button, and the next display to appear
should be a green screen with the word GREEN displayed
at the bottom of the screen. Press the blue car button to
obtain a blue, white, and finally a grey screen. After the
grey screen, the display will repeat the same sequence.
If the display characteristics are not correct, refer to the
video display manual for the color-purity adjustment pro¬
cedure or the possible cause of failure.
Press the red start button to obtain the next screen.

Convergence Test
The Convergence Test screen is shown in Figure 3-17.
This test indicates the condition of the display size, cen¬
tering, linearity, and convergence.
A violet dot pattern displays the red-to-blue convergence.
Press the blue car button to obtain a white-dot conver¬
gence pattern. Convergence between any two colors
should not exceed 0.7 mm in the middle of the screen
and 1.2 mm in the corners. This pattern can also be used
to set up screen size, centering, and brightness (black
level).
Press the red start button to obtain the next screen.
Accounting Information
The Accounting Information is shown in Figure 3-18.
This screen provides a visual check of the current game
statistics. The statistics information is accumulated either
from the first time the game was turned on or from the
last time the statistics were reset.
