Installing a Numeric Coprocessor Your computer has a socket for a numeric (math) coprocessor. You can install either a Cyrix Cx387SLC or an Intel 387SX/SL multifrequency coprocessor. Installing a numeric coprocessor speeds up your computer's numeric calculations and graphic displays when you are using certain application software. The coprocessor chip can be easily damaged and is expensive to replace; so if you don't feel confident about installing it yourself, ask your Authorized Epson Servicer for assistance. To install the coprocessor, follow these steps: 1. Remove the access cover as described on page 5-11. 2. Place the coprocessor onto the socket so that the round indentation indicating pin 1 is in the upper right comer. Then press it down firmly. 5-16 Connecting Optional Devices
