specific to MVME2603/2604 modules configured for use with
MVME712M transition modules.
VMEbus Connector P2
Two 160-pin 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 VMEbus
specification. P2 rows A, C, Z, and D provide power and interface signals
to the MVME712M transition module. P2 row B supplies the
MVME2603/2604 with power, with the upper eight VMEbus address
lines, and with an additional 16 VMEbus data lines. The pin assignments
for P2 are listed in the following table.
