Models F/G/H/I and 8x7 Systems
All I/O occurs through the HP Precision Bus (HP-PB) on Models F/G/H/I
and 8x7. Figure B-5, “Basic Addressing on Models F/G/H/I and 8x7
Systems,” illustrates the bus relationships in simplified form, for
addressing purposes. Two multi-function (personality) cards can be
configured on HP-PB:
