The 3400 only has like one capacitor can on the motherboard. The damage from a dripping pram battery is usually the killer.

If he used a different power board that has 2 caps on it I'm sure he is correct about the motherboard.

Having 3 dead ones myself and 1 working it's normally the motherboard under the pram battery that is damaged.

I fully agree with points 1 & 3. The PRAM battery placement is a design flaw, yes, but who'd a thunk anyone would be worried about it 18 years later.

Point 2. I'm not understanding this. AFAIKT there's only one version of the PMU. Am I missing something here?
