The PCMCIA committee set out to standardize a way to add credit-card size peripheral devices to a wide range of personal computers with as little effort as possible. There are two type II/I or one type III PC Card slots found on the left panel of the notebook. These slots accept credit-card-sized cards that enhances the usability and expandability of the notebook. ZV (Zoomed Video) port support allows your system to support hardware MPEG in the form of a ZV PC card.
