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/texture scaling graphics. Hardware-wise, it crosses the bridge between the Sega System 32 and the 3D polygons of the Sega Model 1 and Model 2. The H1 Board uses hardware similar to the Sega Saturn, ST-V and Model 2. Only two games are known to use the H1 Board. [1]
