| Trying to bring Roadblasters cockpit back to life. |

Hi all, I'm trying to breathe life back into a Roadblasters cockpit and could use some help. The boards are getting 5v and 12v but won't boot. The clock pin #15 shows pulsing on my logic probe, as does pin #18 for reset. The screen remains light green. The test switch does nothing. I have removed and reseated socketed chips. I don't have a scope. Can anyone provide any further suggestions? |

Screen. It straightens out to light green with no lines after warming up. |

Screen changes to this if I ground the WDIS tab for the watchdog. |

I feel bad that no one here seems to know how to help after two days. I would try asking at KLOV. By some amazing coincidence Roadblasters was the "MACHINE OF THE MOMENT" when I just checked there home page. http://www.arcade-museum.com. |
