Processor Direct Slot (PDS)

The LC-PDS is compatible with the PDS in the Macintosh LC family of computers, but it is not a true PDS. Like the expansion slot in the other models in the Power Macintosh and Performa 5000 series, this expansion slot supports many PDS cards designed to operate with the MC68030 bus.

While the I/O expansion slot accepts PDS cards designed for the Macintosh LC family of computers, some of those cards do not work. PDS cards designed to interact with the main processor—to provide, for example, a RAM cache or an FPU—will not work in the I/O expansion slot.
