History
ADB was created by Steve Wozniak, who had been looking for a project to work on in the mid-1980s. Someone suggested that he should create a new connection system for devices like mice and keyboards, one that would require only a single daisy-chained cable, and be inexpensive to implement. As the story goes, he went away for a month and came back with ADB.
The first system to use ADB was the Apple II in 1986. It was subsequently used on all Apple Macintosh machines starting with the Macintosh II and Macintosh SE. ADB was also used on a number of other 680x0-based microcomputers made by Sun, HP, NeXT and such.
The first Macintosh to move from ADB was the iMac in 1998, which featured USB in its place. The last Apple computer to have an ADB port was the "Yosemite" Power Macintosh G3 in 1999. No machines being built today use ADB for device interconnection, but up to February 2005, PowerBooks and iBooks still used the ADB protocol in the internal interface with the built-in keyboard and touchpad. Subsequent models used a USB-based trackpad.

Famous quotes containing the word history:
“In the history of the human mind, these glowing and ruddy fables precede the noonday thoughts of men, as Aurora the sun’s rays. The matutine intellect of the poet, keeping in advance of the glare of philosophy, always dwells in this auroral atmosphere.”
—Henry David Thoreau (1817–1862)
“If you look at history you’ll find that no state has been so plagued by its rulers as when power has fallen into the hands of some dabbler in philosophy or literary addict.”
—Desiderius Erasmus (c. 1466–1536)
“If usually the “present age” is no very long time, still, at our pleasure, or in the service of some such unity of meaning as the history of civilization, or the study of geology, may suggest, we may conceive the present as extending over many centuries, or over a hundred thousand years.”
—Josiah Royce (1855–1916)
