 | | Zuse learned that one of the most difficult aspects of doing a large calculation is keeping track of all intermediate results and using them, in their proper place, in later steps of the calculation, Zuse realized that an automatic-calculator device would require three basic elements a memory, a control, and a calculator for the arithmetic. |
 | | After Zuse constructed his first three digital computers during the war, he was unable to convince the Nazi government to support his work, for a computer based on electronic valves, the proposal was rejected on the grounds that the Germans were so close to winning the War that further research effort was not necessary. |
