problem (nothing worst that trying to trace logic faults on a PCB with
bad connections!).
I'll second that.
Another thing that fails is the power connector, where the wires from
the transformer and the smoothing capacitor arrive at the motherboard.
I ended up soldering the wires directly to the pins, and putting another
connector in the middle of the cable so I could get the board out.
