The Enhanced Cartridge Interface or (ECI) was a 14-pin extension to the cartridge slot on Atari 8-bit XE computers. This allowed external devices access to the system's data and bus lines. It was functionally compatible with the Parallel Bus Interface (PBI) on the XL computers.

The ECI was found on the 65XE (European version) the 130XE and the 800XE.
