Is there an adapter to use PC Cards on a system with only ExpressCard slots? How about the other way around?
There are adapters that allow the use of older PC Card products on systems without a PC Card slot through either the ExpressCard or USB interfaces. See this page for information on available adapter products for PC Card/CardBus cards. Additionally, if you currently have a PC Card application that you would like to continue to use, many notebook systems on the market today offer both an ExpressCard and a PC Card slot, meaning you can continue to use your PC Card hardware alongside any new ExpressCard modules you wish to acquire. This PC Card to ExpressCard adapter is designed to allow you to use an ExpressCard wireless broadband modem (such as the Verizon Wireless V640) in a CardBus slot, so that you can use the same ExpressCard wireless broadband modem inside machines with either a CardBus or ExpressCard slot.
