Note that your cache memory sockets may not look exactly like
the ones illustrated here. If you’re not sure how to install cache
memory chips, contact the EPSON Connection and ask for
assistance.
Installing the External Cache Chips
Follow these steps to install the external cache chips:
1.
Locate the external cache memory sockets on the main system
board, shown on page 3-5.
2.
If there is an option card in your way, remove it. See
page 3-17 for instructions.
Caution
To avoid generating static electricity and damaging the
cache chips, ground yourself by touching the metal
surface on the inside of the computer’s back panel. Then
remain as stationary as possible while you install them.
