A good way to learn how a computer operates is to analyse and build a SAP (simple as possible) computer architecture. It is described in a book by Albert P. Malvino with the title Digital Computer Electronics and it shows all the parts that are present in a computer design. Before we can start with the architecture we will need to build this clock circuit. It is initially designed and presented in a youtube video tutorial by Ben Eater. Although I have build this circuit on a breadboard I wanted a stand alone small PCB module with SMD components. This will be a start in order to complete my SMD based SAP1 computer.

The whole project is described at: http://ezcontents.org/debounced-clock-circuit
