Quoted from WonderMellon:
I have a few bulbs out. There does not seem to be a lamp matrix chart. I can't really make out the list in the schematics to a chart. Does anyone know if a lamp matrix chart exists, and if so point me in the right direction?
There is no lamp matrix chart. There are two pages in the print that tell you which light has what color of wire and its connector pin location.
E.G. the first light in the list tells you that it is "blue left side" with wire color of brown with black stripe. And it travels to connector J1-pin 18 on the LDA. This is the blue light on the left side of the orbit. Sometimes it is a bit of a struggle to figure out which light is which because of the way the engineers labeled them.
Try this: halfway down you see
1) Drop Target Increase (Middle) This is the big white X light in the middle 4-place drop assembly.
2) Drop Target increase (Bottom) This is the big white X light in the middle 4-place drop assembly.
OK. You now have the middle drop and bottom drop assemblies located. Where is the Top Drop Target at?
You will find down low. It is #6 from the bottom and is is just called "Target Increase". This is your top drop target assembly.

And this pic from the LDA page shows the same thing.

Bally blueprints from the same era are all nice and neat with clean writing by the engineers. Stern's drawings are a sloppy mess. In some cases a doctor's handwriting would be better
