Actually, I would only describe the ARPANET as the _operational_ predecessor
to the Internet; for the "architectural predecessor" of _all_ internetworking
systems, I would look to CYCLADES/CIGALE.

We did use the ARPANET in building the Internet, both as a tool (to exchange
e-mail, files, etc) and also also the WAN communication substrate (a role for
which it was IMO quite badly suited, for reasons I won't elaborate unless
people want to hear them). And of course we took over the _applications_
(e-mail, file transfer, remote login, etc) more or less whole.

But architecturally, with the move of key functionality into the end-points,
the Internet took a very different path from the ARPANET - a path pioneered

BTW, in "all internetworking systems", I would include PUP, which might also
be worth covering briefly, since I gather the PUP guys did influence TCP/IP
somewhat - the exact level would be an interesting historical research
project for someone...
