Techknight, those are very reassuring comments. Thanks a lot for that. I'm feeling better about things - I'm also enjoying the speed boost as a result of the overclock I performed at the same time.
I'm also finding out a lot about the functionality of System 7.6.1 that I never knew, because my family went from System 7.1 on a Mac LC straight to 8.5 on an imac.
It sounds like your preventative work paid off. I was quite surprised by the buildup under the old caps when they came off, because the motherboard looked 'clean' unlike my LC 475, which was clearly leaking EVERYWHERE!
