I think there is more required than just that.
I have an ADM-3a at home and also the technical manual for it,
so if I remember to look it up I could check on this.

I don't think the ADM-3 was able to do much more than emulate a
"glass KSR-33" except for the addition of direct cursor addressing.
Many screen-oriented text editors require features such as erase-to-
end-of-line, which the ADM-3 may not have had.

I will say that the ADM-3(a) terminals were marvels of logic circuit
design.  Every function was accomplished by hard-wired logic, not by
a microprocessor.  However, they didn't provide anywhere near the
functionality of more modern terminals.
