Thanks Britt! My board isn't leaking at all, your PMU reset worked great! But... Now I've got another problem. My 40MB internal HDD (40SC) and previously dead 1.44/800K Floppy drive are both gone. A working mac... with no boot media! What Now? The HDD makes a noise that sounds like *high pitched squeal* click, *high pitched squeal* click, *high pitched squeal* click, etc.
