Installing a Math Coprocessor

Your computer has a socket on the main system board to accommodate an 80387DX, 33 MHz or 3167,33 MHz math coprocessor. A math coprocessor speeds up your computer’s numeric calculations and graphic image displays when you are using certain application software.

It is best to have your dealer install a math coprocessor for you, since it is a delicate component that can be damaged easily if it is installed incorrectly.

If you install it yourself, be sure to read the manual that came with your math coprocessor, if you received one. Then follow the steps in this section to install it in your computer. Before you begin, be sure to read all of the instructions and warnings carefully so you do not injure yourself or damage the coprocessor or your computer.
