Notes:
1.
These signals are provided primarily for reference, as this is typically an “internal”
connector inside the system without direct user access.
2.
Names in italics refer to the naming of this pin for the older UBUS24 24-bit backplane.
Accessory boards designed for the Turbo PMAC UMAC CPU use these signal
designations.
3.
“rsvrd” means “reserved for future use”
4.
“B” as the first letter means “buffered”
