Anticipating availability of its implementation of the 10BaseT standard for Ethernet local area networks, National Semiconductor Corp’s Computer Enhancement Group has introduced a pair of Ethernet adaptor boards for MS-DOS micros designed to be used on 10Base-T networks. Called EtherNode, the boards are Novell-certified adaptors which run in NetWare 286 and 386 environments. EtherNode-16AT is fully compatible with the Novell NE-2000 Ethernet adaptor, EtherNode-8PC with the NE-1000. The EtherNode-16AT adaptor board is designed for the AT bus, but can also operate in an 8-bit slot. Towards the end of the year, says NatSemi, the boards will be equipped for 10Base-T unshielded twisted-pair wiring. Converters will be available to upgrade thick coaxial cable Ethernet adaptors to 10Base-T via a 10Base-T Medium Attachment Unit attached to the IEEE 802.3 Ethernet Attachment Unit Interface. Both EtherNode boards are available now. Single-unit pricing is $375 for the EtherNode-16AT, and $315 each for the EtherNode-8PC.
