Windows 9x and Windows NT driver for the Viking Components 56K ISA internal modem. Strange that the FCC ID number shows it was built by Digitan Systems yet the disk that came with it is mark Viking Components.... Has a Lucent 1641B chipset. Driver is self extracting to a 1.44 mb floppy. After downloading, just double-click the file in Windows Explorer and it will extract to floppy once you click the UNZIP button in the box that appears on screen. A NT help file is also included that will show how to install properly in Windows NT.
