2810 HD/20  (250-3551)    Adding a Math Coprocessor     Faxback Doc. # 1807

Note: Refer to Faxback Doc. # 9002 for Catalog Number and installation 
location information.

Graphical design programs that perform a large number of mathematical
computations require your computer to do a lot of work. These types of
programs can take additional time to run unless you have a math coprocessor 
in your computer. A math coprocessor allows your computer to run these 
types of
programs much faster.

CAUTIONS:
* Once the math coprocessor is installed, you should use a special chip
  extraction tool if you want to remove the coprocessor. Be sure to correct-
  ly position the math coprocessor.
* Be sure you touch a grounded metal object before handling the coprocessor.

To install a coprocessor, use the following steps:

1. Exit any program you might be in and turn off your computer.
2. Remove the battery.
3. Remove the two screws from the compartment cover.
4. Orient the math coprocessor as shown in the socket. Use the small hole 
   on the chip's top surface and the slanted corner as guides.
5. Press down the math coprocessor until it snaps into place.
6. Replace the compartment cover, and reinstall the battery.
7. Turn on your computer.
