 //**Z2**//   The Z1, Z2, Z3, and Z4: His computers should be free programmable, it means that they should read arbitrary instructions from a punch tape, they should work in the binary digit system because Zuse wanted to contruct his computer with binary switching elements.

Unsatisfied with the reliability of the binary switching metal sheets he constructed the Z2. The Z2 used the mechanical memory of the Z1, but for the arithmetic and control unit he used relays (800 relays) from the phone companies. SEBASTIAN PEREZ
