In Apple's first major computer, the Apple 2, the speaker was under software control, but only by a single bit. The programmer could write a one to it to turn the speaker full on, a zero to turn it full off. The programmer could make sound by modulating the writing of ones to the speaker. The modern Apple product, the Mac, has an 8 bit D-A converter connected to the speaker, allowing for many more possibilities in the machine's sound. Similarly, the original Mac had a one bit disk ejector. Now we are told that more modern machines have a variable ejector control. Think of the possibilities!
