The connector marked A[7:0] contains the 8 least-significant bits of the external SRAM address bus. The purpose of the connector is to provide easy access to the address bus. The 8 most significant bits can be found on the “Ram High Addresses” jumpers or the Port C connector.
The connector is placed after the latch as shown in Figure 1.
This connector is handy when using the SRAM interface to interface external devices.
