1958: standard modular system
The standard modular system
The standard modular system was a printed board assembly with integrated circuits. A transistor is a switch controlling conduction. It consists of three ports. One receives the conduction and an other hands it over back to the electronic circuit. The third port is for the lower controlling stream, which activates the transistor. When activated, the transistor allows the conduction to flow.
By fitting together many transistors and other elements can be created very complex chains of commands that are adapted from logical terms. Those are also called transistor circuits.
