midway INVASION the abductor-clock chip replacement

apparently this is the same board as MK4?

anyway, I need help to determine where the clock chip is and what to replace it with. (if possible)
 
what makes you think the clock chip is the problem?

In test mode:
sound test says:GOOD
system test says : sounds GOOD

burn-in test: CLOCK ERROR 05

yellow led on the board while it's running is solid (should be flashing) indicates locked up
 
Your clock circuit is not going to be just a single IC. Find some schematics and take a look. Locate the crystal oscillator on the schematics and look at everything tied to it. Once you identify the parts you can start doing a real good visual inspection of the boards traces around those parts. I would do this before moving on to any real troubleshooting.
