3800 HD  (250-3533)          Math Coprocessor           Faxback Doc. # 1437

Note: Use Math Coprocessor (900-2586).

Graphic design programs or programs that perform many mathematical 
computations require your computer to do a lot of work. A math coprocessor 
allows your computer to run these types of programs much faster.

CAUTION: Be sure you touch a grounded metal object before you handle the 
coprocessor.

To install a math coprocessor, do the following:

1. Exit the current program and turn off the computer.

2. Remove the battery and disconnect the AC adapter.

3. Remove the two screws from the battery compartment cover and lift off 
   the cover.

4. Position the math coprocessor in the socket, as shown. Use the small hole 
   on the chip's top surface and the slanted inside corner of the chip's 
   socket as guides to properly align the chip.

CAUTION: Be sure to correctly position the coprocessor. Once you install the 
coprocessor, you must use a special chip extraction tool to remove the 
coprocessor.

5. Carefully press down the coprocessor until it snaps into place.

6. Replace the compartment cover, and reinstall the battery.

7. Turn on the computer.
