A.4. Static memory expansion connector

The memory connector signals are listed in Table A.3. The signals on this connector interface to memory devices mounted on an attached expansion board.

Note

The memory expansion connector consists of two 48-pin connectors placed end to end. The connector has one position (pin 35) blocked so that the interface board cannot be installed incorrectly.

If a Versatile/AB-IB1 or Versatile/AB-IB2 interface board is installed, a memory module can be connected to the interface board.
