BA40A Expansion Adapter
The BA40A Expansion Adapter is an optional attachment for the MicroVAX 2000/VAXstation 2000 system unit that permits communication between the expansion box and the system unit.
The Expansion Adapter contains two connectors: A and B. Those letters are stamped on the Expansion Adapter to identify the connectors. A is the connector for an expansion box containing a tape drive. B is the connector for an expansion box containing a fixed disk drive.
A third opening C (rightmost) is provided for the connector of one of the mutually exclusive options:
The Expansion Adapter is connected to the MicroVAX 2000/VAXstation 2000 system unit by one or more flat cables through corresponding rectangular openings at the bottom of the MicroVAX 2000/VAXstation 2000 system unit and at the top of the Expansion Adapter.
