Controller/transceiver board drives Ethernet into PC domain (personal computer)
Bob Metcalfe · Mini-micro Systems · 1983
Until very recently, the cost of connecting microcomputers to the Ethernet local network was prohibitive to both pesonal-computer makers and users. But the introduction of VLSI controller chips, refinements in Ethernet transceivers and space-efficient board design have brough Ethernet connection within the realm of the second-generation, 16-bit-based microcomputer. By putting the transceiver on the controller board and using VLSI data-link controllers, it is possible to provide a complete local-network connection, including software, for less than $1000 per station. Initially aimed at IBM Corp.'s personal computer, 3COM Corp.'s Etherseries provides the Ethernet physical and data-link control layers at board level and supplies networking software for such applications as file and printer sharing and electronic mail. The product's levels of networking service allow flexibility of configuration and implementation by both oems and nonprogramming end users.
