The MultiFaceCard III is a full length Zorro II card providing 2 extra serial ports and 1 extra parallel port. The buffered serial ports of the MFC are superior to the A4000s stock serial port, as RTS/CTS-handshake is done by the hardware itself. This makes high-speed transfers more reliable and reduces the CPU load, making the Amiga more useable during the transfers. (Editors note: the MFC card uses the 68681 serial UART, which has a three-byte FIFO buffer.) The parallel port is capable of higher speeds than the stock A4000 parallel port. As this port is bidirectional, it can be used with a special version of ParNet found on the install disk. Theres no ROM or EPROM on the card, and thus no drivers that autoconfig. You have to run the MFC program which provides the "duart.device" for the serial ports and the "pit.device" for the parallel port.
