Abstract
We have seen that the instructions the Apple // operates with consist of sequences of numbers. But just how are these numbers stored internally? Well, not wishing to baffle you with the wonders of modern computer science, let’s try to simplify matters somewhat and say that each instruction is stored internally as a binary number. Decimal numbers are composed of combinations of 10 different digits, that is, 0,1,2,3,4, 5,6,7,8, and 9 and are said to work to a base of 10. As the name suggests, binary numbers represent the two different electrical conditions that are available inside the Apple // computer, namely, 0 volts (off) and 5 volts (on).
