Power-up CPU Self Tests
Upon power-up, thè CPU board performs a series of self tests of major components. Turn thè game on whlle
observlng thè LEDS on thè CPU board. Tests of thè PIAs, RAM, and EPROMs are performed automatlcally and
results of thè test are indicated by thè PIA LED.
With all tests passed, thè LEDs illuminate in thè following sequence at power turn-on. Thè PIA and +5V LEDs
Illuminate Immediately. Approximately 1/2-second later thè PIA LED goes out and thè Blanking LED illumlnates;
