Multiple independent custom processors with a 32-bit RISC CPU armed
with a double-speed CD-ROM that jams out 360,000 polygons and full-frame
video at 30 frames per second. 360-degree camera movement. CD-quality sound.
Digital lighting and texture mapping capabilities. And, the ability to
display 16.8 million colors, simultaneously. You can also check out the
playstation
