So I still haven't purchased a voltmeter yet (work all day) but late last night I did bite the bullet and popped her open. I was definitely the first one to do that to her. I couldn't so much as see a fingerprint in there! And, surprisingly, I could barely find traces of dust! The inside of her looked immaculate! I only peeked inside for a few moments before I went to bed. But from what I can see the analog board is looking good. I couldn't find any signs of bad capacitors or that. It's def a first rev analog board tho, as it has the metal shield across the top. The board is original the original as well, no signs of any mods in here. It looked so new in there, that I just couldn't touch anything yet! I'm going to get a antistatic bad before I go poking around in it and that. I'm taking things with extra caution on this one!

Now, I was just wondering. If an analog board goes bad, you can get a bum display or no sound out of the speaker right? (as well as volt fluctuations) but anyways, I plugged headphones into the audio out on it, and flicked the switch just to see. I don't hear the start up bong out of it either. I hear a click through the headphones when I turn it, so obviously some sort of power is coming there. But later on, if I probe the floppy port and fine the volts are good, does this mean I'm probably looking at a bad logic board?
