I have been restoring my Macintosh IIsi in my spare time and it appears that my work has paid off. At first, it would not boot because the caps leaked out onto the motherboard. If I was lucky, I would see Mac OS loading up and then it freezing or going to a blank screen. What I did was (And tell me if this is wrong) take all of the little circular caps off of the board and then deep cleaned the board (I did not put it in the dishwasher). Now it boots up everytime and doesn't freeze or crash.
