Docking Stations
PowerBook Duos lacked most common ports (featuring only one internal printer/modem serial port and an optional fax/modem card port). In their place was docking ability, accomplished via a unique 156-pin Processor Direct Slot (PDS) giving the docks full access to the Duo's central processing unit (CPU) and data buses. Several dock options were offered by Apple and third parties.

Famous quotes containing the word stations:
“A reader who quarrels with postulates, who dislikes Hamlet because he does not believe that there are ghosts or that people speak in pentameters, clearly has no business in literature. He cannot distinguish fiction from fact, and belongs in the same category as the people who send cheques to radio stations for the relief of suffering heroines in soap operas.”
—Northrop Frye (b. 1912)
