TAM hack: Apple External Video Connector


Well-known member
Hi all,

Most 5x00, 6x00 and 580 Macs come with a small connector on the motherboard for external video support.  Apple made an adapter, part M4099LL/A which provides functionality for a mirrored display output (not dual display sadly) for these machines.

The TAM being based off a 5500/6500 board also has this connector, but no-where to mount the DB15 port.  My lowly USB card has enough space to fit the connector with just enough room for a DB15 to VGA adapter on the other side.  In doing so, it's great to be able to plug the TAM video output to an external monitor, TV or projector!  It's an exact mirror ouput with no performance hit.
