Sorry for bad photos. LC III was in storage for about 15 years, and yes it had the darned Maxell battery installed, which went bad and sprayed all the toxic guts out some time ago.The corrosion was even worse, but I managed to clean it about 70% off the board. The case is also corroded, but nothing serious. Still the brown stuff remains (it won't go off easily) and some traces are eaten off.

Is the board fixable? What do you think?
