Sun Microsystems’ acquisition TOPS – it now calls itself TOPS, a Sun Microsystems Company has gone outside the family and appointed Mt Xinu Inc – that’s Unix tm (for trade mark) backwards – of Berkeley, California as its agent to implement TOPS networking and file sharing software on computers running Unix. Under the agreement, Mt Xinu will provide TOPS ports and support to manufacturers and resellers of Unix-based software and market TOPS software and hardware products as part of XInet, its Unix system networking package. The TOPS Network currently enables Apple Macs and MS-DOS micros to share files, disks and printers directly and transparently. TOPS markets TOPS/Sun Workstation, networking software that enables Sun stations to function as file servers to micros, and the TOPS/XInet combination will enable other Unix minicomputers and micros to be used as file servers to networked Apple Macintoshes and MS-DOS personal computers. Unix computers on a TOPS network already provide a gateway between TOPS and Sun’s widely used Network File System standard for Ethernet connectivity.
