Installing a Math Coprocessor You can install a math coprocessor in your Equity LT-386SX easily. If your software supports a math coprocessor, it processes mathematical calculations much faster than without the coprocessor. Follow these steps to install the coprocessor: 1. Turn off the computer, close it, and disconnect all cables. 2. Turn the computer upside down, with the handle away from you. 3. Remove the cover for the coprocessor socket by putting your fingernail or a coin into the recession on the bottom of the cover and lifting up. 4. Insert the 80387SX coprocessor chip into the socket so that the round indentation indicating pin 1 is in the upper righthand corner, and the writing on the chip reads downward, as shown below.
