The following tables summarize the pin assignments of connectors that are 
specific to MVME2603/2604 modules configured for use with MVME761 
transition modules.

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 MVME761 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.
