You can try this: http://www.boardgamegeek.com/filepage/52059/oldschool-charts Not sure if this is what you are looking for. It gives the steps but not an explanation. The only thing wrong with this but is easily fixed is the US starting income. You could also try this: http://files.boardgamegeek.com/file/download/4hyb4h8s4w/AnA_reference.jpg? but I think it will be the same for you. I have some in my group that forget a couple of the steps and the charts in the first link above has been helpful in remembering the steps to play. Enjoy AA42. This is the only game, besides Revised, that I have in the AA lineup and really enjoy it.
I just reread your post and saw that you have already checked out BGG but not sure if you saw the two items that I linked.
