New, boxed, original Apple External Video Connector for the LC 580 and Performa 52xx, 53xx, 54xx, 55xx series Macintosh. This is a small circuit board that connects to the proprietary video expansion socket on the logic board, with an attached ribbon cable with an Apple D15 monitor socket and mounting plate at the end. Comes with mounting hardware and users guide.

It can also be used with the Twentieth Anniversary Macintosh (TAM) although it is not officially supported. The required video slot is present on the logic board because it is based on the 5500/6500 board, but there is nowhere on the casing for the external monitor connector. The connector can either be left hanging loose outside the casing or, as some users have down, a hole can be cut for it on the PCI cart face plate.
