Configuring the Apple Super Serial Card
Configuring the Super Serial Card takes two steps: setting the jumper block and setting the DIP switches.
See the Apple II Super Serial Card User’s Manual.
The Apple Super Serial Card
Make sure that the triangle-shaped mark on the jumper block points to TERMINAL. If it does not, gently
unplug the block from the card (using a flat-bladed screwdriver or a chip puller), rotate it accordingly, and
plug it back into the card.

Installing and Connecting the Serial Interface Card
With your card properly configured, follow the instructions in this section to install the card, connect the
serial interface cable, and test the connection.
Important!
Before working with internal parts, turn off the computer’s power switch, remove the computer’s cover,
and touch the power supply case to discharge any static electricity that has accumulated on your clothes
or body.
Follow these steps:
Slide the nut plate onto the ribbon cable. Make sure the nuts on the nut plate face away from the 25-pin
connector.
Sliding the Nut Plate Onto the Ribbon Cable
Hold the connector and nut plate up to one of the large openings in the back panel. It’s best to choose
one of the openings near slot 1.
Positioning the Connector and the Nut Plate
Attach the 25-pin connector to the back panel using the screws and wrench that came with the Super
Serial Card. Don’t overtighten the screws or you could bend the connector.
