1970s computer workstation

The **NuMachine**, or **Nu Machine**, is an early [microprocessor](/source/Microprocessor)-based [computer workstation](/source/Workstation) designed to interface with [local area networks](/source/Local_area_network). It was developed in the late 1970s at [MIT](/source/Massachusetts_Institute_of_Technology)'s [Laboratory for Computer Science](/source/Laboratory_for_Computer_Science) (LCS) by Professor [Steve Ward](/source/Steve_Ward_(computer_scientist)) and his research group in concert with [Western Digital](/source/Western_Digital).[1][2] The NuMachine is [68010](/source/Motorola_68010)-based running at 10 MHz.[3] The project included the development of [TRIX](/source/TRIX_(operating_system)), a [Unix](/source/Unix) operating system variant.

The NuMachine was first developed commercially by Western Digital, but they decided not to enter the workstation business.[3] It was bought by [Texas Instruments](/source/Texas_Instruments) in 1983.[4] Texas Instruments dropped the NuMachine development in 1985 in favor of the [TI Explorer](/source/TI_Explorer).[5]

Its main legacy is a bus architecture called [NuBus](/source/NuBus) that was later adopted by [Apple Computer](/source/Apple_Inc.) for its [Macintosh II](/source/Macintosh_II) and by [NeXT](/source/NeXT), and influenced the design of the [PCI bus](/source/Peripheral_Component_Interconnect). The TRIX operating system was used by the [GNU Project](/source/GNU_Project) for its first attempt at an operating system [kernel](/source/Kernel_(operating_system)).
