Z3 reconstruction video
In this video the reconstruction of the Z3 is shown. It was shot on the 9.1.2002. On the left you can see the calculating unit and on the right the memory. The console of the Z3 with which the next executive operation and the operands were chosen was substituted with a PC in the replica. Like the original Z3 the reconstruction can perform the following operations: addition, subtraction, multiplication, division, square root and the conversion of decimal into binary digits and vice versa. Above the calculating unit you can see the stepping switches which are responsible for the control of the operations. The memory stores 32 floating point digits per 22 bits (1 bit for the algebraic sign, 7 for the exponent and 14 for the mantissa).
