| Fast Facts on the Sega X Board
Made by: Sega
The Sega X Board is an arcade system board released by Sega in 1987 as a successor to Sega OutRun hardware. It debuted with After Burner and Thunder Blade.
The X Board specification is largely similar to that of the OutRun Hardware board, however allows for twice as many sprites on screen at once and twice as many tile layers. The contents have also been condensed onto a single board making it slightly easier to manufacture.
The X Board would be succeeded by the Y Board, before the Model 1 made true 3D arcade games more financially affordable.
