Midway TERMINATOR 2 JUDGMENT DAY Operation Manual Addendum page 20

CPU Board Test
The CPU Board Test (much like the Start-up Test) allows the
operator to check the RAMs and ROMs.
Select the CPU Board Test with any Start Button then, press
either trigger to activate the automatic test of the CPU
Board's RAMs and RO Ms. When this test is activated, a "rug"'
pattern appears on the screen. The screen then changes to
show the layout of the RAMs, and RO Ms on the CPU. Any
chip that is shown as black with a white outline is part of the
CPU and should tum either red or green during the CPU Test.
Any chip that is shown as gray with a white outline is not
installed in the game. During the test, chips are good,
if
they
tum green; they are faulty, if they turn red.
Pre~s either trigger to exit back to the Diagnostic Menu.
Sound Board Test
The Sound Test allows listening to some of the sounds that
the game is capable of producing. This test also emits a tone
for each fault that is detected.
Select the Sound Board Test with any Start Button then,
press either trigger to activate the test. The screen displays
two test options:
GENERAL TEST analyzes the sound circuitry. A successful
test causes a single "tone" to sound. Detection of a fault
causes a series of tones or no tone at all to sound. To enter
this test, or exit back to the Sound Test Menu, press either
trigger.
PLAY SOUNDS tests synthesized
&
digitized sounds from the
Sound Board. Enter and advance through this test by
pressing either trigger. Repeat a sound by pressing the Bomb
Button. Exit this test by pressing any Start Button.
Select RETURN TO MAIN MENU or BACK TO DIAGNOSTIC
MENU with any Start Button. Press either trigger to activate
your selection.
