That is correct.

Yes. Alternatively, the firmware that is running while in 80-column mode
with many if not most II+ 80-column cards will handle the shift-key mod
transparently to the program that is running.

That's all there is to it. Typically the signal is taken off the comb pins
between the two keyboard boards.
