the thumbnail shaped cut out is standard on ALL ic's, with the ic in front of you and the thumbnail at the top (ic pins down), pin 1 is the top left. Please ignore the "."'s in the middle of my ic drawing, bl00dy stupid thing wont draw it proper if I leave spaces
The above pic shows a 12 pin ic, same goes for all, start at 1 and go down, then back up the other side, DO NOT plug it in the other way!!
Next time you wave - use all your fingers
