The R4000 models, usually known as MIPS Magnums or Magnum 4000, will
work in either endian mode.  In the little endian mode, it is
supported by the NetBSD/arc port.  It is also known as Microsoft Jazz.
In big endian mode, no free OS that I'm aware of supports this.  The
big endian mode support would be nice because you can run that with a
serial console while the little endian mode requires a special,
expensive video card.
