This sounds like what Commodore did the Amiga 1000. It had a seperate proc for Graphics nameed Denise, one for sound named Paula and the other was the central chip named Agnus or Fat Agnus in the second chip set. There were a lot of benefits to this design and at the time of its release it was a superior configuration when compare to the PC or even MAC at the time of its release.

Atari may have come before the Amiga but the Amiga also used coprocs and it blew the Atari into a black hole.
