There is my replacement circuit diagram. There is two CPU-s PIC12F675, one for focal and other for zoom.
Power for them is taken from camera "mother board".
1) dismaunted sensor from lens
2) dissassembled lens. You need from there outer most case, as it holds rest of camera together, and shutter. Shutter is needed cause without el-mechancal shutter exposure time is not controlled correctly. It is possible to take pictures, but there will be horisontal lines on picture and exposure time is much longer than choosed.
I put shutter right in front of CCD(I suppose). Shutter hole is smaller than CCD size so about 25% is obscured.
