Operating system

Novell S-Net Developer Novell, Inc. OS family Network operating systems Source model Closed source Initial release 1983 Available in English Supported platforms Motorola 68000 License Proprietary Official website www.novell.com

**S-Net** (aka **ShareNet**) was a [network operating system](/source/Network_operating_system) and the set of [network protocols](/source/Network_protocol) it used to talk to client machines on the network. Released by [Novell](/source/Novell) in 1983, the S-Net operating system was an entirely proprietary operating system written for the [Motorola 68000](/source/Motorola_68000) processor.

Physically, S-Net used a star topology to allow up to 24 DOS and/or CP/M machines to connect directly to the 68B server machine. Ethernet and ARCnet were both considered but dismissed on cost grounds. S-NET used cheap dual twisted-pair phone wire and since each client computer was directly connected, the need for complex network addressing was eliminated. The 68B server ran NetWare/S-Net

S-Net has also been called **NetWare 68**, with the 68 denoting the 68000 processor. It was superseded in 1985 by [NetWare 86](/source/NetWare_86), which was written for the [Intel 8086](/source/Intel_8086) processor. NetWare/86 which came in several editions and paved the way for the subsequent monolithic version of NetWare.
