Well, it is, and it isn't. The board is drawn with the 'bottom' (in DEC
nomenclature, for when the board is inserted in a backplane where the slots
run vertically) at the top of the drawing, and vice versa.

But, other than that, it appears to be correct - based on the keyed slots.
(So, the first land, at the bottom of the drawing, which is the 'top' of a
DEC board, normally, is AA. And the last - top of the drawing, 'bottom' of
the card when it's in vertical slot - is DV. Etc, etc.)
