Abstract
We examine the decays t --> cgamma and cZ0 in the Standard Model with an extra scalar doublet and no discrete symmetry preventing tree-level flavour changing neutral currents. The Yukawa couplings of the new sc alars are assumed to be proportional to fermion masses, evading bounds on FCNC's from the light quark sector. These rare top decays may be v isible at the SSC.
