A pulsar wind model which has been successful in accounting for the observed radiation from the Crab nebula is used to estimate the power and energy of accelerated particles in SN1987A and the resulting gamma-ray line and continuum fluxes in terms of the pulsar period and surface magnetic field strength. For a pulsar period less than approx.10 ms (or spin-down power greater than 10/sup 39/ erg/s) pion-decay gamma rays at TeV and possibly PeV energies should be observable with ground-based detectors in the Southern hemisphere. Nuclear excitation line fluxes of C, O and N are small compared to the 1--10 MeV continuum flux of synchrotron radiation from TeV electrons. This electron continuum flux should be detectable and may be comparable to the expected line fluxes from radioactive decays.
