VMEbus Connector - P1

Two 160-pin DIN type connectors, P1 and P2, supply the interface between the base board and the VMEbus. P1 provides power and VME signals for 24-bit addressing and 16-bit data. Its pin assignments are set by the IEEE P1014-1987 VMEbus Specification and the VME64 Extension Standard. They are listed in the following table.
