286compatible

286compatible refers to a class of personal computers that are designed to be software-compatible with the original IBM PC, introduced in 1981. This compatibility is achieved by adhering to the same hardware and software specifications as the IBM PC, which was based on the Intel 8088 microprocessor. The term "286compatible" specifically denotes computers that use the Intel 80286 microprocessor, which was introduced in 1982 and offered improved performance over the 8088.

The 80286 microprocessor supported a 24-bit address bus, allowing for a 16 MB address space, compared to the 8088's 20-bit address bus with a 1 MB limit. This increase in address space enabled 286compatible computers to support more memory and peripheral devices, making them more versatile for a wider range of applications.

Manufacturers of 286compatible computers aimed to create affordable and high-performance alternatives to the IBM PC. These systems often included features such as expanded memory, improved graphics capabilities, and enhanced processing power. The compatibility with IBM PC software ensured that users could run a wide array of business and personal applications without the need for extensive modifications or additional licensing.

The 286compatible market was significant during the mid-1980s, as it provided consumers with a more cost-effective option compared to the original IBM PC. This period saw the rise of several prominent manufacturers, including Compaq, which became a leading player in the personal computer industry. The success of 286compatible systems laid the groundwork for the development of more advanced and powerful personal computers in the following years.
