[Tim] noticed recently that a large number of projects recreating discrete logic tend to do so with technology around 70 years old like resistor-transistor logic (RTL) or diode-transistor logic (DTL).

When the microprocessor and inexpensive ROM memory arrived in the early 1970s, building small, stored-program computing systems became practical. System designers learned that with the rapidly growing ...

As we have observed in previous parts of this course, in a digital system, signals can take on only two values: high or low. These values are often represented by two voltage levels. The most used ...
