Diversifying furiously in all directions, Western Digital Corp of Irvine, California has now launched a menu-driven local area network operating system for Personals and PS/2s running under MS-DOS 3.10 or above. Claimed to be cost effective for networks with upwards of just two nodes, ViaNet Professional will run on StarLan, Ethernet, IBM PC Network and Token-Ring nets using standard adaptors. It includes an automated network manager and a Unix-like security system for large installations. According to Western’s Chet Brown, the product’s ability to run over dif-ferent types of networks gives users access to a virtually unlimited range of applications. NetBIOS compatibility provides connectivity to IBM SNA hosts, asynchronous hosts and X25 networks. OS/2 and Unix System V.3 connectivity will be provided in due course.
