In addition, there are 64 pins of I/O from PMC slot 1 and 46 pins of
I/O from PMC slot 2 that are routed to P2. The two PMC slots may
contain two single-wide PMCs or one double-wide PMC.

PMCspan Expansion Mezzanine

An optional PCI expansion mezzanine module or PMC carrier
board, PMCspan, provides the capability of adding two additional
PMCs. Two PMCspans can be stacked on an MVME230x, providing
four additional PMC slots, for a total of six slots including the two
onboard the MVME230x. Table 1-2 lists the PMCspan models that
are available for use with the MVME230x.

PCI Mezzanine Cards (PMCs)

The PMC slots on the MVME230x board are IEEE P1386.1
compliant. P2 I/O-based PMCs that follow the PMC committee
recommendation for PCI I/O when using the 5-row VME64
extension connector will be pin-out compatible with the
MVME230x.
The MVME230x board supports both front panel I/O and rear
panel P2 I/O through either PMC slot 1 or PMC slot 2. 64 pins of
I/O from slot 1 and 46 pins of I/O from slot 2 are routed directly to
P2.
