History

The AT keyboard was first introduced by IBM in 1984, as part of the IBM Personal Computer/AT (PC/AT) series of personal computers. The PC/AT was a significant upgrade over the original IBM PC, and the AT keyboard was designed to take advantage of the new features and capabilities of the PC/AT.

The AT keyboard quickly became the standard keyboard for IBM PCs and compatibles, and it remained the most popular type of keyboard for many years.

In the late 1990s, USB keyboards began to replace AT keyboards as the standard keyboard for personal computers. USB keyboards offer a number of advantages over AT keyboards, such as hot-plugging capabilities, increased speed, and improved power management. However, AT keyboards are still commonly used in older computers and in industrial settings, as they are known for their durability and reliability.
