[ih] Early sockets discussion paper

Yes. The documentation for that BBN API is here (see bottom post on that page):
https://www.rfc-editor.org/rfc/museum/tcp-ip-digest/tcp-ip-digest.v1n1.1

For the interested, I've posted a few pages with notes on the evolution of the Unix arpanet API here:
https://ruizendp.home.xs4all.nl/notes.pdf
The notes only cover making connections, but similar analysis can be done for other parts of the API.

Checking and refining this is why I'm after that TR/4 report.

Thank you for posting that, it looks like carton #2 is interesting. I'll contact the librarian about that.
