"Bids came back from some of the biggest names in the business: both IBM and Raytheon were interested, but the contract was ultimately awared to an influential early computer research firm in Cambridge, Massachusetts, called Bolt, Beranek and Newman, ...
"Connected by telephone lines leased from AT&T, they would send and receive data, check for errors, and ensure that data successfully reached the destination."
"Different makes and models of computers did not need to be designed to understand each other-all they needed to do was communicate with the IMPs. In a way, IMPs were the first Internet routers."
"Finally, in July 1968, Roberts put out a contract request to over a hundred computer companies and military contractors."
"IMPs were the generic gateways to ARPA's network, functioning independently of the computers that used them."
"Over time, the group came up with a design: key to the network would be what Roberts called interface message processors, or IMPs. These were dedicated computers that would form the connective tissue of the distributed network."
1969 "The very first ARPANET node, powered by the IMPs, went live on October 29, 1969, linking Stanford to UCLA."
1970-1971 "Six months later, seven more nodes became operational. By the end of 1971, more than fifteen nodes existed. And the network kept growing."
1975 "'ARPA scientists created something new in computer communications with this device, it's known as the IMP, the interface message processor. Different computers communicate in different languages."
1975 NBC - Ford Rowan's ARPANET Expose on the US Army, CIA, DIA, NSA, Rand Corporation and more than 20 universities.
