Observations of the millisecond pulsar PSR1937+214 using a divided-bar gravitational-wave detector are reported. The detector instrumentation is described: piezoelectric transducers, mounted between two half-bars (total mass 300 kg) and having a coupling coefficient of 0.18, a mechanical quality of 2200, and an overall noise temperature of 5 K or less, were connected via filters and a two-phase lock-in amplifier to a signal averager triggered by a 5-MHz clock compensated for earth-motion Doppler effects. Frequency resolution for the 8-hour run was of the order of 3 parts in 10 to the 8th. No signal could be detected around 1284 Hz (twice the rotation frequency of the pulsar), implying an upper limit of gravitational-wave amplitude on the order of 10 to the -20th. The need for higher resolution measurements to study the rotational dynamics of the pulsar is indicated.
