To test were everything goes ,
Go back from programmer socket towards chip.
So , put 1 probe of your multimeter on A13 , the switch it to continuity beep test-mode and verify the three cd4015's pin 4 with the other probe .
One of them should give a beep noise on your multimeter.
So , then you know which chip has number U5b
and so on , and on , and on...........
