Line-In Jack

This jack is used to attach record/playback devices such as cassette players,
CD players, and VCRs. Connect the line-out cable from any of these
devices to the line-in jack.

Line-Out Jack

This jack is used to attach computer speakers. This jack is amplified, so
speakers with integrated amplifiers are not required. Connect the audio
cable from the speakers to this jack.

Microphone Jack

This jack is used to attach a standard personal computer microphone.
Connect the audio cable from the microphone to the microphone jack.

Video Connector

This connector is used to attach a video graphics array (VGA)-compatible
monitor to your computer.

Serial Connectors

Default port designations: COM1 for port 1 and COM2 for port 2. You can
reassign the serial connector's designation if you add an expansion card
containing a serial connector using this designation.
If you set the computer's serial connectors to Auto in system setup and add
an expansion card containing a serial connector configured to a specific
designation, the computer automatically maps (assigns) the integrated
ports to the appropriate COM setting as necessary.
Before you add a card with a serial connector, check the documentation that
accompanied your software to make sure that the software can be mapped
to the new COM port designation.

Keyboard Connector

Attach the keyboard cable to the 6-pin connector on the back panel.
