       I am placing this message on the net instead of direct in the event that
is of public interest.

MMoon.es,
       Thank you for responding.  I am not certain that the problem is one of
alignment, this was my best guess at the problem.  In response to your
questions:

       o The performance is not noticably dependent on whether the drives are
               warm or cold
       o The DJ2D board is memory mapped and is engaged by subroutine calls to
               an onboard prom (E000-FFFF)

       The major factor affecting performance is whether single density or
double density is being used.  There are far fewer bad sectors at single
density
than at double density.  Unfortunately, the CP/M with the DJ2D will not fit on
the first two tracks in single density.
