3830 SL  (250-3573)        Math Co-Processor            Faxback Doc. # 1217

Some programs, such as some spreadsheet programs, take considerable time to 
run. You can install a 25 MHz 80387SX or 80387SL math coprocessor (PLCC 
68-pin), which often makes these types of programs run faster. To install a 
math coprocessor, follow these steps:

1. Run Setup383 and set Resume to OFF. Then, turn off the computer and 
   remove the battery.

2. Carefully use a pointed object, such as a straight pin, to remove the 
   rubber plug on the back of the computer. Then, remove the screw you 
   expose.

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

3. Open the display panel fully as shown. Then, remove the center cover.

4. Carefully install the coprocessor straight down into the socket so that 
   the slanted corner of the coprocessor matches the socket.

5. Replace the cover and secure it with the screw you removed earlier. Then, 
   replace the rubber plug.

CAUTIONS:

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

* Be sure you install the coprocessor correctly. Incorrect installation 
  might damage the coprocessor and computer.
