In reference to the discussion of the differences between static and dynamic 
binary translation, HP has a large body of HP3000 customers they want to move
to their proprietary OS that they run on the Spectrum.  Consequently, they
put a lot of time into the binary translation problem.  They translate all
they can statically, but they also can do complete emulation at run time --
this was necessitated by the fact that the 3000 has an instruction which
causes the top of the stack to be executed as an instruction, ouch!
