Sounds low: Compaq Computer Corp president and chief executive Eckhard Pfeiffer reckons that IBM Corp plans to make only 1m PowerPC 601 chips this year – and there has been talk of Apple Computer Inc taking 2m of them: IBM is currently the sole source of the 9W 601, but Motorola Inc will and IBM will both make the low voltage – 3W – smaller, cheaper PowerPC 603; many see the 601 as a stop-gap and the 603 as the first mass-market processor.
