Caution
Removing the existing microprocessor requires the use of a
chip puller. The microprocessor 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.
Depending on the type of microprocessor you are installing,
you may need to adjust one of the processor switches. If you
need to set the CPU type switch, you must do so before you
install the processor chip. See “Setting the Processor Speed,
CPU Type, and Voltage Switches” for more information.

Follow these steps to replace the processor chip :
1.
Remove the keyboard as described on pages 4-13 to 4-15.
2.
