Most of the other computing machines of this era were also not Turing complete ( e.g. the Atanasoff-Berry Computer , the Bell Labs relay machines ( by George Stibitz et al. ) , or the first designs of Konrad Zuse ) .
For example : the Atanasoff-Berry Computer , the Harvard Mark I electro-mechanical relay machine , the Bell Labs relay machines ( by George Stibitz and others ) , or the first designs of Konrad Zuse ) .
