PC Card Slots
There are two type II/I or one type III CardBus PC Card
slots found on the right panel of the computer. These slots
accept credit-card-sized cards that enhance the usability
and expandability of the computer.
PC Cards (formerly PCMCIA) are add-on cards for portable
computers, giving you expansion possibilities long afforded
by desktop PCs. Popular type II cards include flash
memory, SRAM, fax/data modem, LAN and SCSI cards.
Common type III cards are 1.8-inch ATA drives and cellular
modems. CardBus improves on the 16-bit PC card
technology by expanding the data path to 32 bits.
