Subject: Anyone have a source listing for BIOS w/DTC520 controller??

   I'm looking for a sample BIOS source listing for a z80 with a DTC520
controller.  I found a bunch of controllers at a great price and am wondering
what i'm getting myself into in trying to incorporate some of these into
some machines i have.
 
   this controller supports 2 hard drives and 4 floppies.  It uses a
proprietary host interface, but i have all the information needed to build
the host adaptor.

   Z80 opcodes would be preferred, but since beggars can't be choosers, i'll
struggle with 8080 opcodes if need be.

   I've been wanting to play around with new fast Z80s for a while and this
controller seems like just the ticket for such a project, since i won't
have to worry about building a hard disk interface, just the host adaptor
and a little bit of software.
