John's data on the Snakes machine is incorrect.  The HP9000 models 720 and 730
have a 64-bit memory bus and are capable of 2 word/clock transfer rates.
Thus, the correct "Streaming MFLOPS" for these machines are:

        HP/9000 Models:
               720      = 400/24 = 16.7  MFLOPS
               730      = 528/24 = 22.0  MFLOPS
