> PowerPC and POWER are not the same. AIUI PowerPC is essentially an extended (original) POWER. The AIM alliance defined PowerPC which had 32bit and 64 bit modes, and IBM also added ISA extensions - the PowerPC AS or "Amazon" - for its AS/400 line. When the POWER3 came around, the original 32Bit POWER ISA was deprecated, but still included for backwards compatibility. So all POWER chips since then implement the PowerPC ISA.
