Epson EQUITY 386/33 PLUS - Manual (Page 73)

Follow these steps to install an option card:
1. Remove the computer’s cover as described in Chapter 3.
2. If you are installing an option card that controls a mouse, you
need to change the setting of jumper J2 on the main system
board before you install the card. If you install a display
adapter card, you may need to change the settings of
jumpers J1 and J4. See page 4-4 for instructions.
3. Remove the retaining screw from the top of the metal option
slot cover; hold on to the screw so it doesn’t fall into the
computer. Lift out the slot cover.
Keep the screw to secure the option card to the computer.
Store the slot cover in a safe place in case you remove the
option card later.
