PowerBook Duo 210

The PowerBook Duo was a 4.2 lb subnotebook that became a desktop Mac when it slid into a dock. To save size and weight it had no floppy drive and few ports of its own. The docks added the floppy drive, NuBus slots, an external monitor and the standard Mac ports. The 210 was the entry Duo, with a 25 MHz 68030 and a 9.1-inch passive-matrix screen with 16 shades of gray.
