  I have used the Radius Accelerator 16 in my SE.  It comes with an init
  which corrects the sound output.  The error comes from the accelerator
  running at 16MHz while the sound driver on the motherboard is still
  geared for 8MHz.  The only problem with the Radius accelerators is that
  I think all of them are based on the 68020.  I don't think they have
  put out a 68030 based accelerator yet, and you can't install a PMMU into
  their 68020 accelerator board.  They really should put out an '030
  version since MacPluses and SEs are limited to 4MB of RAM on their
  motherboard, hence making the ability to use virtual memory a
  virtual necessity for memory hungry users.
