If you want a nice graphic peacockmaps.com probably has something - I am looking at their lovely maps of the internet poster (on my wall) and can see that, in December 1969, a sigma7 at UCLA, a 360 at UCSB, a PDP10 at Utah and a 940 at SRI were the four computers. The map also describes the state of ARPANET in September - not much of a network - just the sigma7 at UCLA and the first IMP.

See http://www.isoc.org/internet/history/brief.shtml, for instance, as well as the Internet Growth table at http://www.sharpnet.co.uk/winter.shtml (it's at other places as well). The computers actually connected were called Interface Message Processors (IMPs), smaller computers that performed the packet switching, and built by Bolt Beranek & Newman (BBN). Host computers connected to these - but at first, only one to each. See http://www.engineer.ucla.edu/stories/2004/Internet35.htm. See the 1969 entry for the Hobbes Internet Timeline (http://www.zakon.org/robert/internet/timeline/) for the actual computers connected the IMPs. Neil Randall When ARPAnet connected the four universities in 1969, were there only actually four computers connected to each other? If not, does anyone know how many? A source (not Wikipedia or your personal memory) for this information would be much appreciated.
