NuBus (/ˈn(j)uˌbʌs/) is a 32-bit parallel computer bus, originally developed at MIT during between 1978 and 1979 as part of the NuMachine workstation project, and standardized by the IEEE in 1987. The first complete implementation of the NuBus was done by Western Digital for their NuMachine, and for the Lisp Machines Inc. LMI Lambda. NuBus was later incorporated in Lisp products by Texas Instruments (Explorer), and used as the main expansion bus by Apple Computer. A variant called NeXTBus was developed by NeXT for their workstation systems. It is no longer widely used outside the embedded market.
