The Hamburg Quasar Survey is a wide-angle objective prism survey for finding bright QSOs in the northern extragalactic sky (|b|>20°; δ>0°). The taking of the prism plates for 567 fields covering this area was completed in 1997. Including direct plates for fields with δ> 20° 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 15≤B≤19.5 and redshifts z≤2.8 collected over various parts of the sky, for which objective prism plates were available at that time.
