IBM Corp’s RS/6000 is to be one of two preferred architectures for the new generation of Uniplex client-server office automation software products due out at the end of this year from the IMI Plc subsidiary. Uniplex is using the IBM RS/6000 as the major development system for its Medley software. There is no longer a need to implement our software on such a wide range of systems, said Uniplex managing director Patrick Regester, speaking at IBM’s South Bank centre in London last week. IBM, and the other, undisclosed partner, will have a significant lead time with the new product, he said. Speculation has it that Hewlett-Packard Co, already working with Uniplex on Open Mail, could be the other supplier, but Digital Equipment Corp and even Sun Microsystems Inc might be in the running.
