It was a button that generated an NMI? How weird to put that on the front panel of a Mac. Then again Sculley was doing some weird stuff...

  The programmer’s key came with the original Macintosh, letting you hit NMI https://en.wikipedia.org/wiki/Programmer%27s_key https://en.wikipedia.org/wiki/Programmer%27s_key

    IIRC, the keyboard “Restore” key on the Commodore 64 also generated its own interrupt.
