Q: Is ExpressCard technology compatible with PC Card technology?

A: No, these technologies are not compatible with each other. The PC Card interface uses either an ISA-based 16-bit or PCI-based 32-bit parallel interface through a 68-contact pin-and-socket connector. The ExpressCard interface uses high-speed PCI Express or USB 2.0 serial interfaces through a 26-contact high-performance beam-on-blade connector.
