The Binary Telephone

By K. Manning
Communications Advice Bureau, London

A new discovery that, we think, makes telephones much easier to use. Instead of a complicated 0-9 numbering system, here we have a mobile telephone in the binary system. Simple to use, worry free, and no need to remember a long string of 11 random digits. The HELP button is always available for teething troubles, and in case you get caught out in the wrong base.
