The next tables summarize the pin assignments of connectors specific to
MVME2700 modules that are configured for use with MVME761
transition modules.
VMEbus Connector P2
Two 160-pin connectors (P1 and P2) supply the interface between the

Its pin assignments are set by the VMEbus specification.
P2 rows A, C, Z, and D provide power and interface signals to the
MVME761 transition module. P2 row B supplies the MVME2700 with
power, with the upper eight VMEbus address lines, and with an additional
