Maybe run an emulator directly on the hardware, without any other OS
in the way? That would be the next best thing to implementing the OS
on the bare metal.

Sometimes I think it might be fun to build an emulator based on an
FPGA. Then you wouldn't have any other instruction set in the way,
either. :-)

Has anyone out there done that?
