The '''Sega H1 Board''' is an [[arcade]] board made by [[Sega]]. Hardware-wise, it crosses the bridge between the [[Sega System 32]] and the [[Sega Model 1]] and [[Model 2]], and uses hardware similar to the [[Sega Saturn]] and [[ST-V]]. Only two games are known to use it. {{ref|https://github.com/mamedev/mame/blob/master/src/mame/drivers/coolridr.cpp}}

This teeny-tiny article needs some work. You can help us by expanding it.

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.
