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 8 VMEbus address lines and additional 16 VMEbus data lines.
Rows A, C, Z, and D provide power and interface signals to the
MVME761 transition module in 761 mode.
It is important to note that the PMC I/O routing to row D and Z are not the
same as MVME2600/2700. The PMC I/O routing for row D and row Z is
the same as the PMC mode with the exception of pins Z1, 3, 5, 7, 9, 11, 13,
15, and 17 which are used for extended SCSI.
Note A PMC card installed in slot 2 of a MVME5100 in 761 mode
MUST NOT connect to J24-2, 5, 8, 11, 14, 17, 20, 23, and 26
since they are connected to the extended SCSI signals of the
MVME5100.
The pin assignments for connector P2 in MVME761 mode are as follows:
