The recently discovered 1.5-ms pulsed radio source PSR1937+214 could be close to the onset of rotational instabilities if it is envisaged to be a rotating neutron star which gives interesting lower limits for neutron star masses. We examine here the implications of polar gap models for such a rapidly rotating magnetic neutron star. It appears, on the basis of such models, that a higher fraction of high-frequency microwave radiation compared with the Crab pulsar is an expected result. On the other hand, the outer gap discharge models invoked for longer period pulsars yield a large amount of high-energy radiation which is not observed. The high-energy cutoff in the γ-ray region evaluated from assumed values of the magnetic field inside the light cylinder will be around 1,000 GeV.
