Z1 -
Calculation with Metal Sheets For
many people, but also scientists, it is only very difficult to understand the
functionality of the metal sheets. On the right side you can see the metal
sheets of the rebuild Z1 It is a view in the floating point arithmetic
unit. The secont image shows the metal sheets of the
original Z1 in 1936. With this item Konrad Zuse tested the functionality of the
metal sheets for binary calculations. He checked the Boolean Operation AND, OR
and the NEGATION. As you know, the basic ooperations of a computer are the
Boolean Operations. With them you can realize the addition etc. Question The
question is: How is it possible to make calculations with metal
sheets. We
explain the Negation
The green image right on shows the
electrical relization. The switch is on 0 and the lamp is alight, that means 1.
The image left shows the logical table and left from this you can see the
logical gate.
Above we see the realization of the
negation by Konrad Zuse with metal sheets. The model above uses plastic sheets.
We have the input X (blue)and the result Y. (orange) The input X can have the
two posistions 0 oe 1. The same holds for the result, it also can be 0 or
1. On the right
side you see the cycle. The cycle can also be moved from 0 to 1 and
back. How does it
work? The input X
is set to 0 or 1. The the cycle is moved from 0 to 1 and back. Dependent on the
input X the result Y moves from 0 to 1 or remains in the 0
position. The next images below show the functionality of the
Negation.
Negation Click on the buttons and
you can how the negation works. OR -
Operation
OR -
Operation In the
same kind as explained above the OR-operation works in the same
way.
