Big Book of Amiga Hardware

Half length zorro card which adds two additional serial and two additional parallel ports. The ports can be used simultaneously at full speed (57600) with very little slow down to the system. The Multiface 2 can be upgraded to a "Multiface 4" by the replacement of the crystal and 3 chips. This gives enhanced serial speeds of up to 115,200 but requires version 3 of the driver software.
