Epson Endeavor - Manual (Page 108)

Note
You may find it easier to plug in the cable connector if
you first remove the option card connector board and
diskette drive ribbon cable. To remove the option card
connector board, see page 2-21. To disconnect the
diskette drive ribbon cable, grasp the cable connector
and pull it straight out from the system board connector
so you do not bend the pins; do not pull on the cable.
4. Make sure the holes in the cable connector fit over all the
pins in the system board connector; then push in the cable
connector.
Caution
If you do not correctly align the holes with the pins, you
could severely damage your system board when you
push in the cable connector.
5. If you removed the option card connector board and diskette
drive ribbon cable, replace them now. To connect the
diskette drive ribbon cable, align the tab on the cable
connector with the notch in the system board connector.
Make sure the holes in the cable connector fit over all the
pins in the system board connector and push in the cable
connector. Then replace the option card connector board as
described on page 2-22.
