The '''Sega H1 Board''' is an [[arcade]] system board made by [[Sega]]. It is Sega's last arcade system specifically created for three-dimensional [[Sprite|sprite/texture]] scaling graphics. Hardware-wise, it crosses the bridge between the [[Sega System 32]] and the [[Sega Model 1]] and [[Model 2]]. The H1 Board uses hardware similar to the [[Sega Saturn]], [[ST-V]] and Model 2.
