High Quality Content by WIKIPEDIA articles! Zombie Zombie is a ZX Spectrum computer game by Sandy White. IT was published in the 1984 by Quicksilva. IT is the sequel to the popular Ant Attack, by the same author, and uses the same 'Softsolid 3D' isometric graphics.ZOmbie Zombie also presented two notable innovations. THe first was the utilisation of two-channel sound, a then unheard-of feat of a computer equipped with only a single-channel piezo buzzer as its sound source. THe second was that, through the use of the Sinclair Interface 1, the game's two-channel melodies could be played back on a MIDI-equipped synthesizer. UNfortunately, although a wiring diagram was supplied with the game, the interfacing code had been tested on a Yamaha DX7 with a ROM containing bugs - so the circuit would only work on that particular synthesizer. THis came to light when Sandy White attempted to demo the game whilst connected to an unfamiliar synthesizer.
