The van was parked unused for a decade in a back lot of the SRI campus until the planning of a celebration of the 20th anniversary of the
Internet in 1997 at the Internet Supercomputer Conference in San Jose, California. SRI employees Don Alves and Don Nielson cleaned, licensed, and replenished the

laboratory that housed one of the PRNET radio nodes, to simulate the needs of in-the-field military to connect to the network. As DARPA further wished to connect the disparate computers at its various contractors, and indeed globally, there was a push to test

November 22, 1977, when SRI originated the first connection between three disparate networks. Data flowed seamlessly through the mobile van at SRI in Menlo Park, California and the University of Southern California in Los Angeles via

Network Speech Compression Program around 1977 to 1978. They focused on how to compress speech such that it still sounded "natural" and arrived in a timely manner. The phone in the van was a

November 22, 1977, the latter of which is considered the start of the Internet.

Computer History Museum presented a 30th anniversary celebration of this demonstration, which included several participants of the 1977 event.
