So I need to fix a macintosh classic machine. The battery DESTROYED the logicboard, corroded all the resistors, traces, card edge, even the IC pins. I am working on the analog board which is definitely saveable but Ill need a new logic board. Does anyone happen to have one? Part # 820-0390-03 or 630-0390 attached is an image of what the board looks like.. Its much smaller than the original compact mac boards. If anyone has one please contact me!
