The ADM3 did not perform cursor addressing, which the ADM3A did, making the 3A
much more useful in many applications - I don't think there would be a termcap
entry for a 3.
Btw, on the off chance that these are 3A's, I'll mention that I have detailed
photos of one, as well as PDF's of both the operators and service manuals posted
on my web site:

Look under the "Altair 8800" entry (I use a 3A on the Altair).
