>How-To-Repeat:
        put USB stick into NetBSD computer; it shows up on my amd64 machine as sd4

        # dd if=/tmp/arm64.img of=/dev/rsd4  bs=1m conv=sync progress=1
         or
        # dd if=/tmp/arm64mbr.img of=/dev/rsd4  bs=1m conv=sync progress=1

         add "dtoverlay=disable-bt" to msdos file config.txt
         change cmdline.txt to be "root=NAME=netbsd-root"  -or-  "root=sd0"
         Boot on Raspberry Pi 3 Model B Plus Rev 1.4 with 1G memory
         Console TTY output is as above.
