What was that early B+W T.V. show with man in"Hooded Black cape"

[Vinylrockrob]

Remember as a kid a telly show with a man in hooded black cape and you could'nt see his face and was always turning dials on a main frame type of computer about 6 or 7 ft high with wirring sounds as he turned the dials. The cars in the show look to be about 50's or early 60's models. The word "wizard "rings a bell but I am not sure.Does anyone know of this T.V. show?
