Kerian

Kerian Ltd. published Turbo Chess and Turbo Draughts for the Tatung Einstein, both released in 1985. Turbo Chess credits its programming to C.A. Thornton; both games share the "Turbo" branding and were later sold together as a combined disc under the title "Turbo Chess & Draughts," though the archived copy of that disc is the Chess program alone.
