Notes
1.  LED1 monitors CPU power (+3.3 volts). If his LED is off or blinking, investigate processor circuits. If other
LEDs are off or blinking at the same time, check +5-volt circuits or the game power supply.
2.  LED2 flashes when the hard disk is operating during game play. LED2 may light continuously during startup. If
this LED remains lighted, the hard drive may be locked up or faulty.
3.  Software controls RP63. In this game, RP63 initially indicates program startup stages. This LED is a seven-
segment, alphanumeric display device. Normally, RP63 displays a lowercase “b,” or an “O” pattern with
sequentially blinking segments. During Self-Test screens, RP63 displays a “bouncing bar” that resembles a
hyphen (“-“).
