Is $M_tsimeq M_w$ Ruled Out?

A four generation supersymmetric model is proposed, in which the Tevatron ``top-quark events are reinterpreted as the production of $t^prime$ which decays dominantly to $bW^+$. In this model, $m_tsimeq m_W$, and $trtawidetilde twidetildechi^0_1$, with $widetilde trta cwidetildechi^0_1$. This decay chain, which rarely produces a hard isolated lepton, would have been missed in all previous top quark searches. A narrow region of the model parameter space exists which cannot yet be ruled out by present data. This model predicts a rich spectrum of new physics which can be probed at LEP-II and the Tevatron.
