A pocket size television set that can go anywhere and claims to be the world's smallest TV, was presented at Earls Court, London on September 1, 1966. Miss Bari Lyn Chadwich of Cheshire looks at the Sinclair Micro vision set, designed by Clive Sinclair, a 26 year old Cambridge electronic engineer. Britain's midget TV set is powered by six ordinary penlight batteries. The rectangular face plate of the cathode tube has a diagonal measurement of two inches. The circuit uses 20 transistors, and covers channels 1 to 13 in Britain.
