Intel387TM DX MATH COPROCESSOR

The Intel387TM DX Math CoProcessor (MCP) is an extension of the Intel386TM microprocessor architecture. The combination of the Intel387 DX MCP with the Intel386TM DX Microprocessor dramatically increases the processing speed of computer application software which utilize mathematical operations. This makes an ideal computer workstation platform for applications such as financial modeling and spreadsheets, CAD/CAM, or graphics.
