The power connector2 viewsSomething has obviously gone wrong here in the past too. Could this damage be related to the blown tantalum capacitor in the power supply? This Main board connector is not polarised so perhaps this is what happens when it's plugged in the wrong way around? The red wire contact is almost completely missing inside.May 24, 2016
Cleanup completed6 viewsThe board is now finally cleared of all components with significant corrosion damage and the area thoroughly cleaned remove any remaining nasties. The silkscreen in this area was no longer really attached and simply washed away during the cleanup. I also removed the remaining IC sockets for good measure.

Fear not - we can rebuild him!

Battery removed6 viewsLooks even worse with the battery removed. Bringing this machine back to life won't be easy or quick.May 24, 2016
Leaky battery5 viewsZooming in on the battery, it has clearly leaked at some point in the past leaving a surrounding zone of green coloured corrosion and faded or absent IC labels. Oh dear :-(May 24, 2016
