"The Mathematics Competition Part III"

Having just discovered that Professor Zwiebel's work has actually been the development of a thinking machine, Charles and Elizabeth travel once again to London to take part in the very first energising of this wondrous new creation. Is it possible that such a thing could possibly work? A huge leap forward in technological development is promised if indeed a creation like this will work. A fascinating tale of the infancy of computing, 1930s 1:12 scale.
