This page lists the pinouts of the expansion connectors on the Spartan 3 starter board. It also lists pins that can be used interchangably between connectors.
A1 Connector
The pins marked in orange are connected to the SRAM IO pins. To use them, the SRAM chip enable lines should be driven high. These are pins P7 and N5, which are not on the A1 connector.
