recordings.

entertainment system.

ExpressCard Slot
One 26pin Express card slot is available to support one ExpressCard/34mm or one
ExpressCard/54mm expansion card. This new interface is faster by using a serial bus
supporting USB 2.0 and PCI Express instead of the slower parallel bus used in the PC
card slot. (Not compatible with previous PCMCIA cards.)
IEEE1394 Port
IEEE1394 is a high speed serial bus like SCSI but has simple connections and hot-
plugging capabilities like USB. The interface IEEE1394 has a bandwidth of 100-
400 Mbits/sec and can handle up to 63 units on the same bus. IEEE1394 is also used
in high-end digital equipment and should be marked “DV” for Digital Video port.
