Although the RT Personal Computer has made quite spritely progress in European markets, in the US it ranks alongside the Ford Edsel and the IBM Portable Personal Computer as one of the great no-hopers of our time. Nevertheless IBM pledges to achieve a leadership role in the high-performance Unix workstation world, William Lowe, IBM vice president and president of IBM’s Entry Systems Division, declared at the fifth annual international Unix users’ group conference, UniForum, which opened in at the Dallas, Texas Infomart on Tuesday. Lowe continued by saying that IBM intends to offer a complete set of Unix-based solutions to customers in the technical, engineering scientific communities, and the commercial Unix multi-user environment. And he added that by 1989 the high end of the AIX workstation family will have more than four times the performance and memory of today’s RT Personal. Lowe also said IBM will provide a common operating system, applications, communications features, and documentation across a full range of advanced workstation products that today include the RT and IBM Personal System/2 Model 80. And IBM finally got around to announcing properly all those RT enhancements we reported last week.
