That depends on which DEC world you circulated in...
there's been a termcap
entry for the ADM 3A in UNIX for as far back as my experience goes.
I don't recall seeing them at all in non-university or non-UNIX settings,
though. DEC terminals cost enough that in the notoriously cheap educational
market, people gave serious consideration to other forms of terminals (I
have reciepts from the early-to-mid-1980s for VT100s at around $1,700 each,
which is why Software Results had a mix of DEC terminals and CiTOH terminals,
'101's and '101e's).
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: http://www.parse.com/~ddunfield/museum/index.html
Look under the "Altair 8800" entry (I use a 3A on the Altair).
Regards,
Dave

If I weren't so far from home, I might be interested in one of these terminals,
just to add to the stable I already have (VT52, VT55, VT100, VT101, VT102, VT103,
VT105, VT125, VT220, VT241, Wyse 50, CiTOH 101, CiTOH 101e, Planar ELT320, and
maybe one or two more. I used to have a Beehive, discarded from OCLC, but it
was horribly contaminated in a basement flood 15 years ago and I pitched it).

Yeah, our nspeed setup had commands pre-loaded in various buffers, one
useful macro was (this is wired into my brain at a very low level though
I haven't typed the command in 31 years!) ^BB (Control-B B), execute
buffer B, which:
"erased" the screen (might have been 24 LFs)
move edit point back 12 lines
print 24 lines
move edit point fwd 12 lines (back to original point)
eg. centering your work on the screen and showing + and - 12 lines, eg a
screenful.
I assume everyone knows how teco works... ahem
