If you want to test the machine, it doesn't yet boot a MacROM, but you can
boot a linux kernel from the command line.

You can install your own disk using debian-installer with:

    ./qemu-system-m68k \
    -M q800 \
    -serial none -serial mon:stdio \
    -m 1000M -drive file=m68k.qcow2,format=qcow2 \
    -net nic,model=dp83932,addr=09:00:07:12:34:57 \
    -append "console=ttyS0 vga=off" \
    -kernel vmlinux-4.15.0-2-m68k \
    -initrd initrd.gz \
    -drive file=debian-9.0-m68k-NETINST-1.iso \
    -drive file=m68k.qcow2,format=qcow2 \
    -nographic

If you use a graphic adapter instead of "-nographic", you can use "-g"
to set the size of the display (I use "-g 1600x800x24").
