Trellis Software Inc of Hopkinton, Massachusetts, is issuing an upgrade to its Banyan/Novell Gateway. Version 2.0 of the Gateway provides access to Banyan Vines file services for users of Novell Inc’s NetWare operating system. The Gateway software resides on two dedicated bridge workstations which contain separate network interface cards for each of the two operating systems. The workstations must run MS-DOS 3.0 or above. According to Trellis the access is a critical improvement for many Banyan users, who select the Vines software because of its superior wide-area capabilities. No price change accompanies the enhancement. The Gateway sells for $1,800 per bridge pair, with support for an unlimited number of client workstations.
