Following the Open Software Foundation’s decision to select, amongst other things, the Presentation Manager compatible Hewlett – Packard – Microsoft style guide as part of its user interface, UK software house IXI Ltd, Cambridge, reckons that in future, along with AT&T’s Open Look style from Unix International Inc, these two interfaces will predominate in the Unix community. As such it is adapting its desktop manager program, X.desktop, to conform to the two style guides. Foundation members, including Locus Computing Corp and Interfirm Graphics Systems, have already licensed X.desktop, which is now to be submitted for the Alternative Unix club’s Catalog Technology Program, which provides an on-going review of software likely to be included in a core offering from the Foundation. Parallel Systems International Corp, Laguna Beach, California, has now bundled IXI’s Posix-conformant software in with its parallel processing systems using the Inmos Transputer, Acorn is including it on its R140 RISC-based Unix systems, and BiiN Inc on its fault-tolerant computers.
