Heavy Quark Hadronic Weak Decays from CLEO-II
  We present preliminary results from the CLEO-II collaboration on a variety of hadronic final states of mesons containing heavy quarks. In particular, the pattern of 2-body \B\ decays is now decisively different that that of \D\ and \K\ decays; perhaps a consequence will be that $\tau_{\BM}<\tau_{\BZB}$. We have observed `wrong-sign' $\DZ\sto\KP\PIM$ decays, which are probably due to a doubly Cabibbo-suppressed transition.
