XBOX360 JASPER Identification

Prior to 'JASPER' we had the 'FALCON' series of XBOX. The FALCON had a 65nm CPU, 90nm GPU (earlier version of XBOX had a 90nm GPU). The conventional thinking was that a smaller CPU would produce less heat etc and perhaps cut down on the fail rate (RRoD). So they downsized the CPU and changed the heatsink configuration.
