Frank Heart puts a team together to write the software that will run the IMPs and to specify changes in the Honeywell DDP- 516 they have chosen. The team includes Ben Barker, Bernie Cosell, Will Crowther, Bob Kahn, Severo Ornstein, and Dave Walden.

Four sites are selected. At each, a team gets to work on producing the software to enable its computers and the IMP to communicate. At UCLA, the first site, Vint Cerf, Steve Crocker, and Jon Postel work with Kleinrock to get ready. On April 7, Crocker sends around a memo entitled ‘Request for Comments.’ This is the first of thousands of RFCs that document the design of the ARPANET and the Internet.

The team calls itself the Network Working Group (RFC 10), and comes to see its job as the development of a ‘protocol,’ the collection of programs that comes to be known as NCP (Network Control Protocol).

The second site is the Stanford Research Institute (SRI), where Doug Engelbart saw the ARPA experiment as an opportunity to explore wide-area distributed collaboration, using his NLS system, a prototype ‘digital library.’ SRI supported the Network Information Center, led by Elizabeth (Jake) Feinler and Don Nielson.

At the University of California, Santa Barbara (UCSB) Glen Culler and Burton Fried investigate methods for display of mathematical functions using storage displays to deal with the problem of screen refresh over the net. Their investigation of computer graphics supplies essential capabilities for the representation of scientific information.

After installation in September, handwritten logs from UCLA show the first host-to-host connection, from UCLA to SRI, is made on October 29, 1969. The first ‘Log-In’ crashes the IMPs, but the next one works!
