Addressing computers in a cascade

The addressing format used by the AdderView CATx units

incorporates the various group numbers along with a nal

specic 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.
