Opto Alignment

When mounted to a trough ( such as A-16809-2 ), this board has its Optos aligned in the center of the pill shaped openings. This seems to be more like the alignment of the A-17981-AI / A-17981 board ( 5768-13659-02 PCB ) found in other Williams machines. This seems like a better spot to put them and for my purpose (homebrew), it does not matter as I will align the other board accordingly. If however, you were to use these boards with an existing A-18617 / A-18617-1 you'd probably want the Optos to align at the bottom, in which case you'd use the bottom aligned version of this board.
