Consists of three units, Red Leader, Red 1 and Red 2. Red Leader is the microcomputer that uses the Spectrum as a terminal, from which it can be programmed. Once done, it can be left alone to do its task.
Red 1 is a slave unit that plugs into a standard wall power socket, Red 2 is an infra-red sensor. Both units connect to Red Leader, and can be controlled by it. Each unit can be 'read' and operated individually, and more units can be added. A built-in clock adds further uses, as each unit can be programmed to switch on or off at a given time. Ideal for home security.
