I picked up this dying Macintosh IIci a couple of weeks ago, and have slowly been trying to bring it back to life. Here's what I started with: the PRAM battery was left in and exploded at some point, obliterating the case and corroding the clock chip, ROMs, and other components in the vicinity. Worse, it looks like this computer was set up on its side with the battery on top, so the released juices dripped down the side of the logic board and ate away at all of the ROMs and SIMM slots. All of that in addition to the usual level of capacitor leakage and ensuing corrosion all over the board. I'm not done yet, but it's been a fun project…
