Sega H1 Board
Manufacturer: Sega
Release Date RRP Code

The Sega H1 Board is an arcade board made by Sega. Released in 1995, it was a successor to the Sega System 32 and was the last Super Scaler arcade system board (using sprite/texture scaling for three-dimensional graphics). Hardware-wise, it crosses the bridge between the System 32 and the Sega Model 1 and Model 2. The H1 Board also uses hardware similar to the Sega Saturn and ST-V. Only two games are known to use the H1 Board.
