Benton C Bainbridge creates media art, live performances and interactive installations with custom digital, analog and optical A/V systems. For “Lisa Joy / Dueling Vectrexes” the artist utilised two antique video game consoles cross-patched via a simple hack. Bainbridge inserted patch points between the CPU outputs and the vector displays of a pair of Vectrex consoles. Each remains fully functional, and may be played normally with any game cart. Input and output switching jacks allow participants to mix and mingle horizontal, vertical, and brightness signals between the two objects or from synths and other electronic signals ranging from -5 to +5 volts.
