LED-MC Test
Turn on the slide switch (S1); the display on the LED
MC (U29) should show “00”. Select game 1 by
pressing the A button on the selector (S8), then the
B button.
Every 2 seconds one or more of the following will
happen, randomly changing: D1 lights, D2 lights,
D10 lights, SP2 plays a tune, the U29 LEDs display
a random pattern. Make sure that eventually all
these parts are being controlled. If not, something is
wrong. Also, pushing the press switch (S2) should
turn off the LED display on U29 until you release S2.
If desired, you can speed things up by turning S1 off
and on (to reset the circuit), then selecting game 2
or game 3 by pressing the A button on S8, then the
B button. The tunes played on the speaker (SP2) will
play at the same speed as before.
