Microprocessor Upgrades

The computer's processor can be upgraded by replacing the
existing microprocessor with a faster one. You can either
purchase an upgrade kit from Epson or buy the individual
components separately, as listed in the following table.
Microprocessor upgrade components
*For the SX/25, SX/33, and DX/33 processors
**For the DX/50, DX2/50, DX2/66, and Pentium OverDrive processor
SX/25, SX/33, and DX/33 processors require a heat sink.
DX/50, DX2/50, DX2/66, and Pentium OverDrive
processors require a heat sink and a fan. Make sure jumpers
J16, J17, and J19 are set correctly for the new processor.

Fan Installation

Some upgrade kits for processors that require both a heat
sink and a fan contain a separate fan assembly. Secure the fan
to the bracket using the long screws and the nuts. Then
secure the bracket to the chassis with the short screws.
Connect the fan connector to J12, aligning the small triangle
on the case of the connector with pin 1.
