Locus Computing Corp’s PC-Interface, which enables users to connect MS-DOS-based machines to Unix host systems either directly or as part of a local area network, will be bundled with future reference implementations of Unix System V.4 operating systems. Meanwhile, the Open Software Foundation is still considering taking this Locus product up for its Distributed Computing Environment, so it looks likely that OSF 1 and Unix System V.4 will be transparent at the personal computer interface level. Locus’ MS-DOS integration technology is also bundled with versions of Unix by IBM and Santa Cruz Operation. Locus also provides OEM versions of PC-Interface to more than 40 Unix hardware vendors including Motorola, Dell, Intel, Prime, NCR and others. As a result of the bundling agreement the Locus product will be available on all Unix System V.4 reference ports including Intel 386 and 486, Motorola 88000, Intel 80860, MIPS and SPARC microprocessors. Hitherto, the Locus and AT&T agreement had only stretched to cover Intel processors (CI No 1,423).
