Maybe I'm just an idiot, but I was attempting to wire up board so that it could connect to the TA board through the Bus and I ran into a problem. I was using the Bus Pin Assignments given in Table 2 of the project handout. That table claims that there is a Pin A, B, G, I, and O on the bus connections but on my board these pin numberings are skipped. In other words, when I'm looking at the upper row of pins on the wiring side of my board the pins are numbered C D E F H J K L M N P R S T U V W X Y Z A' B' C' D'. Note that the pins A, B, G, I, and O don't appear. Do I have an atypical board or is the handout incorrect?
