                Who is the difference if the coil is an IB?? What is this that will make the discrimination??

                              and 7808 in the picture pin 3 is output but in schematic is input.and pin 1 in schematic go to +8v but in the pictur input ispin 1. is it correct in shematic?
                              and 7660 pin 5 is output not pin2 is it correct?
