  We determine all D-branes in the non-tachyonic 0'B orientifold, examine their
world-volume anomalies and study orbifold compactifications. We find that the
spectrum of the D-branes contains chiral fermions in the symmetric,
antisymmetric and fundamental representations of (unitary) gauge groups on the
branes. The cancellation of the world-volume anomalies requires Wess-Zumino
terms which we determine explicitly. We examine a non-tachyonic
compactification to 9D whose closed part interpolates between 0B and IIB and
revisit compactifications on orbifolds. The D3-brane allows to conjecture, via
the AdS/CFT correspondence, a supergravity dual to a non-supersymmetric and
infrared-free gauge theory. The D-string gives hints concerning the S-dual of
the 0'B orientifold.
