Some models were equipped with an integrated acoustic coupler and modem that could receive data at 30 characters per second.

Acoustic couplers that could be attached to a normal telephone handset, and later modems, were used.

Released in 1978 for $225, it was designed to work with modems utilizing acoustic couplers.

Prior to that they offered a third party Apple-badged comparatively low-tech acoustic coupler.
