[ih] TCP adoption in 1984

[Greg Skinner]

It occurred to me that some of this information might be inferred from UUCP maps.  Some UUCP Mapping Project <https://stargatemuseum.org/html/the_uucp_project__1984.html> entries contained the operating system the machine ran.  Those sites could have run TCP/IP networks internally that were not (yet) connected to the Internet.

The UUCP Mapping Project started in 1984.  There are mapping entries in mod.map <https://groups.google.com/g/mod.map> that go back to 1985.  net.news.map <https://groups.google.com/g/net.news.map> goes back to 1982, but those were USENET map entries.
