I have a lot of green sockets in one dead a2000. But it worked fine. That green stuff is VERY hard to remove. I've tried replacing sockets (68K and ROM) with no luck.
BTW, I'd say that 'reseating' chips might not be a good idea when there are green pins as it might actually loose contact.
Do you have any solution for those sockets other than replacing them with new ones?
