NuBus was also used both in Apple products, and the TI 1500 series of 68000-based UNIX minis. I installed both 1500s, and the previous Xenix-386 1300s in franchise dealerships in the early 90s. Is the TI machine in the parent article also a 68000? EDIT: Hey, get a load of this! "The NuBus was first developed commercially in the Western Digital NuMachine, and first used in a production product by their licensee, Lisp Machines, Inc., in the LMI-Lambda, a Lisp Machine. The project and the development group was sold by Western Digital to Texas Instruments in 1984. The technology was incorporated into their TI Explorer, also a Lisp Machine. In 1986, Texas Instruments used the NuBus in the S1500 multiprocessor UNIX system. Later, both Texas Instruments and Symbolics developed Lisp Machine NuBus boards (the TI MicroExplorer and the Symbolics MacIvory) based on their Lisp supporting microprocessors. These NuBus boards were co-processor Lisp Machines for the Apple Macintosh line (the Mac II and Mac Quadras)." https://en.wikipedia.org/wiki/NuBus https://en.wikipedia.org/wiki/NuBus

  >Is the TI machine in the parent article also a 68000? No, it's a fully custom CPU architecture and implementation, though they could use a 68020 as the "LX" co-processor. Also their primary competitor Symbolics used two 68000s in addition to their custom CPU: one as an I/O and boot controller, another as the heart of their console i.e. a graphical terminal.

    IIMU that the Explorer's 68K option was the same design as the NuMachine/Lambda 68K board with the addition of a license-protection PAL/ROM combination that prevented Unix from running if a matching paddlecard (containing the license key) was missing.
