After I clean the leaves off of the yard, I should be able to finish the TTY enclosure. I have been wiring the edge connectors first, labelling the wires with port and pin. After the edge connector is wired, I can put it in position, cut wires to final length and solder to the input and output ports. I think this works pretty well.
With this enclosure, the port for the TTY device exits from the reverse end. Here is a view of bundle of wires that will be routed out that end of the enclosure.
