Dear Root Boy Jim:

Alex McKenzie has done his usual thorough job of describing some
of the early history of the ARPANET. My recollection is that the
BSD work was specifically supported by Duane Adams, then a member
of the staff at DARPA's Information Processing Techniques Office.
His interests were less networking than operating system development,
though having such systems work in a networked environment was
high on the priority list.

The BSD implementation for UNIX, coupled with its easy availability
and the proliferation of UNIX-supporting hardware as well as LANs,
sparked the rapid growth of the Internet Protocols. Initially, Digital
VAX equipment dominated the Internet - the PDP-10's had largely
been supplanted by the KL-20's and the Tenex operating system 
replaced by TOPS-20, which incorporated a lot of what BBN had
done with Tenex and the Internet protocols. [You might say that
the network vaxed prolific in those days - late 1970's early
1980's]. 

Since then, new UNIX engines have emerged (e.g. SUN, PC versions
on the 386 series machines, supercomputer versions) which adopted
the Internet protocols because they are both widely available and 
used.
