UNTESTED: I do not have a compatible computer to test this card. Working condition is unknown. Sound output, inputs, and other functions have not been verified. It is listed under “For parts or not working” because operation cannot be confirmed.

Connections include two analog audio outputs, microphone input, line input, and a 15-pin game/MIDI port. Internal audio and expansion headers are present as pictured.

The card shows cosmetic wear, including marks on the PCI contacts, minor surface marks, and scuffs/discoloration on the metal bracket and connectors. Please review the detailed photographs for its exact physical condition.

Includes the pictured sound card and attached metal bracket only. No driver discs, cables, manuals, daughterboards, or original packaging are included.

Requires a compatible conventional PCI slot and appropriate drivers. This is not a PCI Express card.
