A History of the GUI, from the early 1930’s to the present day
“The truth of the story is that the GUI was developed by many different people over a long period of time. Saying that “Apple invented the GUI” or “Apple ripped off the idea from PARC” is overly simplistic, but saying that “Xerox invented the GUI” is equally so.”

Great moments in microprocessor history
The evolution of the modern microprocessor is one of many surprising twists and turns. Who invented the first micro? Who had the first 32-bit single-chip design? You might be surprised at the answers. This article shows the defining decisions that brought the contemporary microprocessor to its present-day configuration.

Konrad Zuse – inventor do primeiro computador digital programável do mundo
Apesar de ser totalmente mecânico (à parte do motor elétrico que provia tração às engrenagens, mas que podia ser substituído por uma manivela) este computador também era completamente digital, usando lógica binária. Só não pode ser considerada uma máquina de von Neumann completa porque não armazenava o programa na mesma memória em que operava os dados, lendo e executando as instruções diretamente a partir de uma fita perfurada.

Konrad Zuse – inventor of world’s first digital computer
It was entirely mechanical (except for the electrical motor which give traction to the machine’s gears, but it could be swapped by a hand-driven crank) and still was digital, using binary logic to perform calculations. However it cannot be considered a complete von Neumann machine because it didn’t stored the program in the same memory as the data being processed, instead reading and executing the instructions directly from punched tape.
