nope.
I was talking about wide area networking pre Internet, Broadband is only
a subset of that, and the term was only invented to describe using phone
lines beyond the audio BASEBAND (i.e. modems). IBM had a world wide
computer network using I think X-25 way back in the early 1980s
TCP/IP and the public internet was quite a latecomer to the scene.
1980 for the adoption of TCP/IP for the whole military and 1983 for the
adoption of it as the standard protocol for ARPANET.
TCP/IP as a complete protocol suite wasn't really completed till 1989.

I fail to see any relevance of that statement to anything else that has
been said.
Are you OK?
