Sharp PC-1245 and CE-125 - Back in action after repairing battery leak corrosion

I like Sharp's range of pocket computers and this particular form factor has become my favourite - a neatly self-contained unit including the computer itself, a thermal printer for hard copies and and a microcassette recorder for program and data storage.

Unfortunately, as with Sharp's other printer options, the CE-125 contains a Ni-CD battery pack that has not handled the past forty years very gracefully - hence the discoloured patch on the bottom edge of the unit from the leaky cells. A few PCB traces had been eaten away and had to be patched over, some wires had wicked up the leak and had to be replaced and a couple of belts in the microcassette recorder had seen better days but after a thorough cleaning, replacing parts and building a fresh Ni-CD pack it's all back in working order.
