Yup, It was spec'ed at least a year ahead and its the code was
committed before the standard was even in a draft vote.
and relatively complete (for a video terminal
application) implementation
of X3.64.
Although different from and the missing stuff was a bear. Originally,
VT100 != X3.64 which has caused many issues over the years. The big
issue was the lack of a proper insert/delete, it used scrolling regions
instead. Kudos to Mary Ann for working through that whole mess years ago!
That's why back in the day, I preferred the H19 and later the Ambassador ;-)
My memory is that was ECMA that got the DEC changes/differences added/put
back/made legal. But originally, there were not. At one point, I had a
copy of the internal DEC documentation (which I think I got from Tom Kent
who wrote much of the rom code and had been on the committee for DEC at one
point, but I don't remember).
