The bus assembly of the ORDINATOR provides the physical housing containing
all the circuit boards and the wiring that connects them. It also contains
the +5V DC and +12V DC power stabilizers that together with the
power supply provide the electrical power for the
circuit boards. The wiring implements the ORDINATOR bus.

The current bus assembly is the third generation of its kind.
The first generation was only a single level and supported a maximum
of 9 circuit boards. When the ORDINATOR grew, we added a second level
to the bus; the result looked much like the current assembly.
Later, all the wiring was redone to fix shorting problems that had
developed over time.
