Main CPU : MIPS R5000 @ Either 144MHz/150MHz/192MHz/200MHz (system clock 48MHz/50MHz)
System Memory : 8MB, 512KB Boot ROM.
Graphics : 3DFX FBI with 2MB frame buffer, 3DFX TMU with 4MB texture memory.
Sound CPU : DCS Sound System (ADSP 2115 @ 16MHz)
Sound Memory : 4MB DRAM, 32KB Boot ROM.
Other Chips : Galileo GT64010 system controller, National Semiconductor PC87415 IDE controller, Midway I/O ASIC.
Board composition : Main PCB and Hard Drive.
Hardware Features : Textured 3D, all normal 3DFX features.
PCB Pictures : Main Board (Larger)
Notes : There are actually 4 types of Seattle board systems, with varying speeds, They will interchange BUT if a 200Mhz game is on a 150 Mhz board, it will run slow during high processing moments.
More notes : This system was also used by Atari, see the Atari Seattle page for details.
Emulators : MAME
