There is a small error in Tom Thompson's feature story "Apple's New Operating System" (June). He asserts that Copland's hardware abstraction layer is "a feature currently found only in Windows NT." In actual fact, IBM's OS/400 and its predecessor S/38 CPF have been based on a HAL since the first S/38 was introduced in the early 1980s.

Our article was describing a new desktop OS, so we were comparing it with other desktop OSes. Just as NT and Copland will probably not appear on an AS/400, OS/400 is not going to be running on a PowerPC or Intel desktop machine anytime soon. -- Tom Thompson, senior technical editor, tom_thompson@bix.com
