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.
