Those custom IC's corrode ALOT..

I work on a galaga for a local pizza place, and get a call on it around once ever 6 months, usually the same thing, random lock up, reboots, etc.

Clean/Reseat the custom chips usually clears everything up for 6 more months or so.


(The sad part is they have 5 games at that location, and the galaga out earns the other 4 put together.)
(The other games are a golden tee golf, ms pac, wrestlefest, Mechanized  Attack.)



Later,

SuperGunGuru:
Here's something else you can look into. Randy Fromm has a cool tutorial on troubleshooting input failures. I have a Simpsons PCB that thinks the player 2 coin mech is constantly active. Using Randy's article, I've found the defective IC and now need to find the replacement.

If you put a thin coating of dielectric grease on the IC legs before you reseated them, wouldn't that help prevent corrosion? Just a thought.
