I've read that in the past.

In some email in the past I recall I got from a person who had
worked at BBN in the early days when this was done.

And if I get really ambitious I'll look up my old BSD code - that
on an impulse I bought from McKuscik.    I just can't read the 
BSD 1 code as it is some bizarre format and compression for
machines that exist in memory and musuems for most people.

Vint Cerf is regarded as one of the co-inventors of TCP/IP.

Shift from Protocols to Agents

   I first encountered the Internet while a student at the University of
   California, Berkeley, in the late seventies. At the time, Ethernet ran
   at 3 Mbps, and most people thought that TCP/IP was fatally flawed and
   would not work well in high-performance networking situations. There
   were published papers purporting to prove its limited performance.

   I was the principal designer and programmer of the Berkeley version of
   Unix (BSD). After our very small group had worked on this project for
   a few years, we received support from DARPA to continue and expand the
   work. Specifically, we gained access to some code from BBN that
   implemented the TCP/IP protocol. Unlike the major technical
   universities (MIT, Carnegie Mellon University, and Stanford), Berkeley
   at that time had not been connected in any major way to the Arpanet.

   Protocol Implementations
   We got our first Internet connection up and working by getting a BBN C
   machine (which connected us to the Net), some C code from BBN
   implementing TCP/IP, and some 3-Mbps Ethernet cards provided by Dave
   Boggs of Xerox (who personally manufactured them after we paid for the
   components). I then designed the "sockets" abstraction for the ISO
   protocol stack and, by rewriting the BBN implementation of TCP/IP,
   managed to prove that TCP/IP wasn't slow, like the literature said,
   but could run at the full speed of our 3-Mbps Ethernet LAN cards.

   My BSD implementation of the Internet protocols was widely
   distributed, along with Berkeley Unix, in source form and became the
   standard code for implementing TCP/IP on a wide range of systems. At
   the time, many governments and other organizations thought that ISO
   protocols would displace TCP/IP, but these protocols didn't have a
   widely available source code implementation that was freely shared,
   and this meant that achieving compatibility among all the
   implementations was difficult. I think it is clear that having the
   source for a quality implementation was one of the major determining
   factors in the triumph of the TCP/IP stack.

The CYHIST archives cover a lot of the past computer history.
It's sort of an oral history proejct. That list had slowed
WAY DOWN in the last couple of years - but there were long
articles from the some of those who originated the pre-Arpanet
implemenations. In the past month there has been more activity
because a lot of the old archives are going to be deleted.

You can check those out at  http://maelstrom.stjohns.edu.
They are planning to take the oldest archives off line shortly so
if you want to snag a snapshot of history 'get them before they are
gone' as they say in so many TV ads.
