A hardware-software combination designed to enable 80386-based microcomputers running under Unix System V.3 to connect directly to Ethernetworks has been introduced by the Micom-Interlan Inc Boxboro, Massachusetts subsidiary of Micom Systems Inc. The $1,390 NP622 package combines the NP600 protocol processor board with TCP/IP – Transmission Control Protocol/Internet Protocol – software from Excelan Corp. Micom Interlan developed the product in collaboration with IBM’s best friend in the Unix world, Interactive Systems Corp of Santa Monica, which is also doing the 80386 implementation of Unix System V.3 for Intel Corp. System V.3 includes the Streams communications feature, and the Micom product will make connection to Ethernet transparent to the user, and developers will not have to write custom interface software to make the connection to Ethernet.
