EXT Port

This connector is only found on older model 1 consoles, all model 1 Japanese Mega Drive consoles, the TeraDrive and Wondermega. It is located at the rear of these consoles, and is essentially identical to the controller ports, though is typically used to send serial data to the VDP instead of being used as an extra controller port. The most notable accessory to use this connector is the Mega Modem, which was only released in Japan.

Note: Diagram pictured is of the connector at the console end.
