hw/m68k: define Macintosh Quadra 800
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").
