     <processor> (HD6309) Hitachi's version of the Motorola 6809
      microprocessor.  Compatible with the 6809, it added
     two new eight-bit registers that could be added to form a
     second 16-bit register, and all four eight-bit registers could
     form a 32-bit register.  It also featured division, and some
     32-bit arithmetic and was generally 30% faster in native mode.
     This information, surprisingly, was never published by
     Hitachi.
