Happy anniversary [w:Internet]! it was 40 years ago, on December 5th, 1969 that the original 4 node network of [w:ARPANET] — the experimental network built with funding from Advanced Research Projects Agency (ARPA) of the US Defense Department — was connected. For more, see the exhibit at the Computer History Museum.
The initial ARPANET consisted of four IMPs. They were installed at:
- UCLA, where Leonard Kleinrock had established a Network Measurement Center (with an SDS Sigma 7 being the first computer attached to it).
- The Stanford Research Institute’s Augmentation Research Center, where Douglas Engelbart had created the ground-breaking NLS system, a very important early hypertext system (with the SDS 940 that ran NLS, named ‘Genie’, being the first host attached).
- UC Santa Barbara (with the Culler-Fried Interactive Mathematics Centre’s IBM 360/75, running OS/MVT being the machine attached).
- The University of Utah’s Computer Science Department, where Ivan Sutherland had moved (for a DEC PDP-10 running TENEX).
