Incorrect. It's documented in IEN-44, June 1978 (written shortly after the
meeting, in the same month).

People were working on Unix in 1977, but it's not the same Unix we know and
talk about today. Does that mean it's not Unix they were working on?

I just specified that it was v4 (see above).

No, with properly-chosen addresses (because of the changes in address
handling), they probably would be.
