the pins marked with a - leave pointing down, these will fit into the original shift register "socket"

The pcb has a silk screen of which way the sr went in, line up the atmega where pin one is on the same side as indicated on the silk screen (facing the cable connection), and where the lasts pins are in the next to last set of holes
