Here are some images of the initial clean up efforts on the Beagle Bros Apple IIGS. You can see that one pin on MC1337 has been completely destroyed, and there is heavy corrosion on several others. As this chip’s only function is to convert the RGB signal to composite, I don’t know that I actually need to replace it since I never use composite monitors with my IIGS machines.
There is still quite a bit of “goo” present on the board, and I will need to clean out the pin holes for C44 and C45 before I can replace those caps. Should be a simple procedure.
And while I’m at it, those expansion connector slots don’t look too healthy either. Not sure of the corrosion I’m seeing in there is related to the leak, but it never hurts to be sure.
You can see the damage to the bottom of the PCB here. I’m not sure what the white substance is.
I’ll continue to keep you updated here, and you can see higher-resolution images in this Flickr set.
