  One thing that I noticed in playing with the DECStation is that it pushes
  data to/from disk much slower than our MIPS M/120-5 (the "mother" of the
  PMAX ???).  I have been told/read that DEC did not implement DMA.  Is this
  true, would this be the reason ?  More to the point, did DEC do anything re
  speeding up disk i/o in the new DECSystems ?
