Jim,

        I once looked into doing this.  I have a rough design for a 
14/15-bit 95khz A-D/D-A board which would cost about $70 ea. to produce.
But what is the point, since the Amiga doesn't have the horses to do
much with such a beast.

        Anyway,  If you look into various A-D converters you will find
that their are a wide variety of 7,8,10, and 12 bit converters aailable,
and that they're are wide variations in the way they are set up (in terms
of how they work and how they're layed out physically).  These parts are
somewhat sensitive, so even if the pins are supossedly the same, the design
useing them may not be.  So, if you don't know the exact chip they're using
in the unit, you will probably have to do your own hardware.

        I don't think they really are trying to keep the individual from
copying the design, rather they wish to make a competetor do their own
design work.  After all, if a rival company has no design costs, they could
aquire half the market just by producing the units and selling them at
the same price.  


                                                        Thanks,

                                                                Wade.

         (oops, used "they're" when I should of used "there", probably
                misspelled "competetor", etc...     Sorry!)
