We have searched the northern sky for pulsars at the low radio frequency of 81.5 MHz, using the 3.6 hectare array at Cambridge, England. The survey covered most of the sky north of declination -20° and provided sensitivities of order 200 mJy for pulsars not too close to the Galactic plane. A total of 20 pulsars were detected, all of them previously known. The effective postdetection sampling rate was 1.3 kHz, and the sensitivity to low-dispersion millisecond pulsars was sufficient to allow the detection of objects similar to PSR J0437-4715 (period 5.7 ms, dispersion measure 2.6 cm-3 pc, mean flux density ~1 Jy). No such pulsars were found.
