VMEbus Connectors P1 & P2 Pin Assignments (PMC mode)
The VMEbus connector P1 provides power and VME signals for 24-bit
address and 16-bit data. The pin assignments for the connector are
specified by the IEEE P1014-1987 VMEbus Specification and the VME64
Extension Standard.
Row B of connector P2 provides power to the MVME5100, and to the
upper eight VMEbus address lines, and additional 16 VMEbus data lines.
Rows A, C, Z, and D provide power and interface signals to the
MVME762 transition module. The pin assignments for connector P2 in
