Hmm. I am going by "Figure 5-7 Teletype Connections", which led me to
expect Relay+ to be connected to the relay, and to the cathode of a diode.
I expected Relay- to be connected to the anode, and also to a resistor,
which connects to the other side of the relay. It shows a capacitor across
the relay contacts, which also connect to the local switch and the reader
solenoid.

I don't suppose I could prevail upon you to trace the connections/schematic
for me?

Thanks!
