Daja, an early chess program written in 1974 by Siegfried Jahn and Ludwig Zagler from Technical University of Munich as part of Jahn's Master's thesis. Co-author and thesis supervisor Ludwig Zagler continued the development on Daja, which evolved to Elsa, the program which participated at the WCCC 1977 in Toronto. Daja was written for a Telefunken TR 440 [1] from Leibniz-Rechenzentrum. Since the computer was too busy otherwise, Daja was restricted to play test games during the night [2] . Daja was runner up at the First GI Computer Chess Tournament 1975 in Dortmund after losing the playoff versus Tell [3] [4].
