In the 80's, I was the project engineer for the Air Force DSP satellite ground communications network upgrade. This system used a 20 MB Bernoulli Box to store the early warning messages. It was replaced in 2005.
This was the system used to pass early warning to the Patriot anti-missile (Scud) batteries during the first Gulf War.
Internetworking the Air Force system to an Army system was considered revolutionary in 1991. Today, it would be equivalent to "stone knives and bearskins".
