Tattoo of the ARPAnet as it stood in 1971

Matt Senate has a tattoo of the ARPAnet as it stood in 1971 -- ARPAnet being the lineal ancestor of the modern Internet. The photo here is from Cyrus Farivar. Here's some relevant Wikipedia verbiage:

In March 1970, the ARPANET reached the East Coast of the United States, when an IMP at BBN in Cambridge, Massachusetts was connected to the network. Thereafter, the ARPANET grew: 9 IMPs by June 1970 and 13 IMPs by December 1970, then 18 by September 1971 (when the network included 23 university and government hosts); 29 IMPs by August 1972, and 40 by September 1973. By June 1974, there were 46 IMPs, and in July 1975, the network numbered 57 IMPs. By 1981, the number was 213 host computers, with another host connecting approximately every twenty days.[15]

In 1973 a transatlantic satellite link connected the Norwegian Seismic Array (NORSAR) to the ARPANET, making Norway the first country outside the US to be connected to the network. At about the same time a terrestrial circuit added a London IMP.[18]

Last Friday, I met @wrought at the @techliminal party. Dude has a tattoo of the 1971 ARPAnet!


  1. The Toronto based IPSAnet’s predecessors, which were covering the world at about the same time, didn’t grow nearly as fast.  It wasn’t until some time in the 80s that I got put on the “Node 256” project which involved finding all the places inside all that self-modifying APL code that a byte was used to store the node number.

  2. EDIT: In 1973 a transatlantic satellite link connected ARPANET to the Norwegian Seismic
    Array (NORSAR), making USA the first country outside Norway to be connected to the array.

    1. After noting the hosts, I saw it to be an outstretched arm with a fist made – much like the arm upon which it sits!  META
