The Hamburg Quasar Survey is a wide-angle objective prism survey for finding bright QSOs in the northern extragalactic sky (; ). The taking of the prism plates for 567 fields covering this area was completed in 1997. Including direct plates for fields with the plate archive contains now 1871 plates. In this paper we present a first list of 121 quasars, which were verified by slit spectroscopy in the years 1986-1991, while experiments to develop efficient selection techniques were made. The sample contains objects with brightnesses and redshifts collected over various parts of the sky, for which objective prism plates were available at that time.
