Notes:
1. Row 25 is physically at th e top of the connector in its “normal” orientation ; Row 1 is at the bo ttom.
Looking from the front of the rack, Column Z is on the left; Column F is on the right.
2. Supply (Vxx & xxV) and ground pins are in the same locations as the Compact PCI bus.
3. Spaces marked (KEY) are for the mechanical key; these are not pins.
4. Pins marked with {} brackets are reserved for future use; the signals inside the brackets are proposed
for future expansion to a 32-bit data bus and 16-bit address bus.
