[ih] ARPANet anniversary

Hi Larry:

The 1977 diagram certainly looks like the early Internet.  I know that
in late 1976 there was router/gateway between SRI and the Packet Radio
network, between ARPANET and BBN's test network (BBN had an internal
network using ARPANET technology used to serve BBN and test ARPANET
code before deployment), and via SATNET at UCL.  Your diagram shows
one more gateway/router in Norway, which is plausible by 1977.
