Sega Fonz hardware was discrete logic Sega arcade hardware that debuted in 1976. It was used for several Sega racing games from 1976 to 1977. This was the first arcade hardware capable of producing pseudo-3D graphics with forward scrolling and sprite scaling in a third-person perspective, making it a precursor to the VCO Object (1981) and Sega Hang-On hardware (1985).
