A distraction at the beginning of the article by R W Munn ( Physics Bulletin May 1988 p202) was the association of a 1 nm linear dimension of a component with the figure of 1000 atoms per bit. With atomic diameters and lengths of bonds between atoms all being of the order of a few angstroms (say 0.4 nm) it is difficult to see how 1000 atoms per bit arises.
