Sega H1 Board

Manufacturer: Sega

Release	Date	RRP	Code

The Sega H1 Board is an arcade system board made by Sega. Hardware-wise, it crosses the bridge between the three-dimensional sprite/texture manipulation of 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]
