In the late 1980s, after enjoying great success in the mainframe computer market, NSC released its first product supporting the TCP/IP protocol, allowing customers to connect their mainframe computers to their emerging TCP/IP-based corporate and research networks. The market was shifting:

    , entered the market with local and wide-area networking products using off-the-shelf components and custom software.
  • Prices for workstations, networking infrastructure and routers plummeted.


NSC found itself in a strange position. Its HYPERchannel networking gear was being supplanted by cheaper and relatively plug-and-play LANs. In addition, the rapid evolution of routing protocols and software was not suited to their products which could neither be upgraded by the customer, nor booted from a server elsewhere on the network. In general, NSC products were maintained on-site by NSC technicians.

By 1995, NSC could not adapt to changing market conditions and merged with StorageTek
