Atari SUPER SPRINT - Pedal Test; Calibration Procedure; Letatest; Alphanumeric Test

Self-Test Super Sprint
Press the blue car button to select the sound numbers
indicated by the CURRENT SOUND message shown in
Figure 3-8. Turn the blue car steering wheel to sequence
through the selected sounds.
The sound status screen also indicates the condition of
the left, right, and auxiliary coin switches. Press the left,
center, and right coin switches, and check the screen for
a corresponding LEFT COIN , CENTER COIN , and
RIGHT COIN message. (See Figure 1-3 in Chapter 1 for
the switch locations.)
Press the red start button to obtain the next screen.
Pedal Test
The Pedal Test screen is shown in Figure 3-9. This screen
indicates the condition of the three foot pedal potentiom¬
eters, A/D converter, blue car and yellow car switches,
and associated circuitry. (It is assumed that the red start
switch works because it was used to advance to this
screen.) The Pedal Test screen is also used to calibrate the
foot pedal potentiometers.
Press the blue car button to obtain the Pedal Test screen
shown in Figure 3-9.
If the range of the foot pedal potentiometers (low to high)
is large enough, then the message OK is displayed next to
the appropriate control range reading. If the range is too
small, then the message BAD is displayed.
Calibration Procedure
The foot pedal controls are calibrated at the factory and
should recalibrate themselves during game play. FIow-
ever, if the foot pedals do not respond correctly, calibrate
each one as follows:
1. Press and hold down the blue car button. Press the red
car button once.
2. While holding down the blue button, cycle each foot
pedal to its extreme up and down positions. Check the
display screen; each foot pedal range should read OK.
Then release the blue car button.
3. I f the problem persists, check the physical alignment
of each foot pedal potentiometer.
Press the red start button to obtain the next screen.
Leta Test
The Leta Test screen is shown in Figure 3-10. This screen
indicates the condition of the steering wheel circuitry.
Each wheel should display a zero value when the wheel
is idle. Turning each wheel in either direction should
change at least one of the zero values to a non-zero value.
Press the red start button to obtain the next screen.
Alphanumeric Test
The Alphanumeric Test screen is shown in Figure 3-11.
This screen indicates the condition of the alphanumeric
ROM, alphanumeric color palettes, and associated
circuitry.
