TheRegister.co.uk reports that Apple will continue to provide PA Semi's low-power PowerPC chip to existing customers, despite the acquisition:
PA Semi's staff has started notifying a limited set of customers that the company's existing dual-core processor will enjoy long-term support. Apple will employ a number of old PA Semi staffers just for this task, which is good news for folks making missiles, mine-sweeping gear and storage boxes.
Apple acquired PA Semi in April, but had no interest in its existing product line. PA Semi had originally told customers that they would be unable to guarantee a supply of their chips in the future. PA Semi's PWRficient processor had reportedly seen quick adoption in a number of Department of Defense projects.
