The PCMCIA slot is an 8 or 16-bit PC Card slot. It is not compatible with the newer CardBus slot.

It exists in older models both as a Type II and Type III implementation. Type III is 2.1 times thicker than a Type II, and most Type III implementations can accept two Type II cards. Type I on the other hand, is 1.515 times less thick than a Type II. This can be summarized as:

  • A Type III slot can accept a Type III, Type II or a Type I card
  • A Type II slot can accept a Type II or a Type I card


Linux support

PCMCIA hotplug and adapters were handled by the older Linux PCMCIA package, until kernel 2.6 where PCMCIA hotplug is now directly supported.
