Sega Y Board

The Sega Y Board is an arcade system board released by Sega in 1988. Just like the X Board before it, the Y Board was known for its sprite manipulation capabilities. Unusually, the system uses no tile layers, so graphics are rendered using only sprites (a design taken by SNK for their Neo-Geo hardware in 1990).

Specifications

• Main CPU: 3 x MC68000 @ 12.5 MHz
• Sound CPU: Z80 @ 4 MHz
• Sound chip: YM2151 4 MHz & SegaPCM @ 15.625 MHz
• Display resolution: 320 x 224
