Comm Slot

The Comm Slot (also Communication Slot or Communications Slot) was an expansion slot architecture that was introduced in 1994 by Apple Computer for the use of lower-cost communications cards in entry to mid-level LC, Quadra, Performa, and Power Macintosh models. It was retired with the release of the beige Power Macintosh G3 in 1997.
