A Twitter poster found a paper his Dad gave him depicting the entire Internet/ARPANET as it existed in May, 1973.

A map of the Internet/ARPANET as it existed in May of 1973 was recently found among papers that were left to a Twitter user by his father. This map depicted the ARPANET, which was the original network from which the Internet grew. If you up-size the image, you can see the names of the institutions connected (labels above the squares) and the kind of connection at the institution (inside the boxes). The type of computers connected to them at each institution are described in the ovals.
