Addressing computers in a cascade

The addressing format used by the AdderView CATx units
group numbers
incorporates the various
specific port number to which a required computer is attached.
In the diagram given here, a portion of the previous cascade
diagram indicates how the routes to particular computers are
formed and addressed.
Each cascade level requires two digits, hence the computer
marked in red requires a unique address with six digits because
it is at cascade level 3, compared to the blue computer at level 2
with its four digit unique address. A computer connected directly
to the AdderView CATx at the top level would simply have a two
digit port number.
The group at level 2 is numbered 41 because it is a quad group,
connected to ports 1, 2, 3 and 4 on the AdderView CATx. If it
was connected to ports 5, 6, 7 and 8, then the group number
would be 42 and the overall address for the red computer would
be 43 42 02.
