A PC card control apparatus includes a PC card connector, a card detector and an interconnection switching circuit. The PC card connector is configured to provide connections for connecting one of a first PC card compliant with specific card standards and a card-adapting card for connecting a second PC card compliant with a different card standard to the PC card control apparatus. The card detector is configured to detect connection of the card-adapting card to the PC card control apparatus and to subsequently output a detection signal. The interconnection switching circuit is configured to switch the connections of the PC card connector to connect the PC card connector to a bus interface dedicated to the second card upon receiving the detection signal from the card detector.
