First question is this one: Who makes the thing? And the next one is: Does a
   driver for it exist within the other members of the Unix community?

One under consideration is made by Diamond Systems.  See
http://www.diamondsys.com/diamondmm16at.htm for a descriptions or
http://www.diamondsys.com/files/dmm16v11.pdf for the manual describing
how to program the board.

I have no idea whether or not there are other drivers for this.

Cheers,
Brook
