We search for the Flavor-Changing Neutral Current decays of the top
quark t -> q gamma and t -> qZ (here q represents the c and u quarks) in pbar
p collisions at sqrt s = 1.8 TeV from a dataset with an integrated luminosity
of approximately 110 pb^-1 collected during the 1992-1995 run of the Collider
Detector at Fermilab.  We set limits on the branching fractions BF(t -> q
gamma) < 2.9% (at 95% CL) and BF(t -> qZ) < 44% (at 90% CL), consistent with
the Standard Model.
