IBM has gone out of its way at this year’s Uniforum to persuade the sceptics that it really does believe in Unix: it has taken 4,000 square feet of exhibition space and it wheeled out Entry Systems chief William Lowe to promise that by 1989, the high end of the AIX workstation family will have four times the power of today’s RT Personal. He also said that IBM was investing as much in Unix workstation development as it did in developing the Personal System/2 line. Separately, in a move calculated to get the rest of the Unix community, which does not trust IBM, up in arms, IBM said that it had been signed by the US National Bureau of Standards to develop conformance tests for applications written to the Posix portable Unix standard being established by the IEEE. Mindcraft Inc, of Palo Alto, California, which has worked for IBM in the development effort, will act as a consultant to the bureau. Development work will be done on an IBM RT Personal Computer under AIX. More Uniforum reports – pages 2, 3
