Announced in September 1989, The Mac Portable was Apple's first attempt at a more easily portable Macintosh. It had a bay for a 3.5" half-height drive, and could support up to two Super Drives. Reaction to the Portable was poor. It was clunky, slow, had no expansion capabilities, and its active matrix screen (later backlit) made it incredibly expensive. It sold for $6,500.
