Deus Ex Machina was a computer game designed and created by Mel Croucher and published by Automata UK for the ZX Spectrum in October 1984 and later converted to other popular 8-bit formats. The game was the first to be accompanied by a fully synchronised soundtrack which featured narration, celebrity artists and music. The cast included Ian Dury, Jon Pertwee, Donna Bailey, Frankie Howerd, E.P. Thompson, and Mel Croucher (who also composed the music). Andrew Stagg coded the original Spectrum version, and Colin Jones (later known as author/publisher Colin Bradshaw-Jones) was the programmer of the Commodore 64 version.
