Definitely true

I did see them in some places.  Microsoft's 11/70 (Miss Piggy) had one as
its console (I suspect it still does, I have to ask Stephen Jones as he has
the system at the ICM).

I disagree here. By November 1973 (Research Fourth Edition release date),
many/most of us might have used an ~$1500 ASR-33 as the console, while,
most often (though somewhat pricey - often $3K-$5 - think the DEC VT05),
glass terminals had already been widely adopted. They were the primary
terminals at every institution I was part of during that time.  For
reference, in 1970, the Tek 4010s were going for $4K-$10K, and they could
not make them fast enough. You should also consider that Research Sixth
Edition was released in May of 1975, and Lear Siegler announced the ADM-3A
in July of 1976 for $995 as a kit or $1045 assembled.
