A French marketing and manufacturing Corporation founded by Frederic Ries. Installed at the angle of rue Baron and rue Roberval - maybe the origin of the Double R name of the Company (Roberval + Ries). Put on the market the first French Chess Computer "La Regence". France Double R went bankrupt, and Sandy Electronics manufactured and sold a "La Regence" with same wood design (with the button legends in German), but different for its hardware and its software version.
