[Milsurplus] BROFICON?

[Albert LaFrance]

A member of the Cold War Comms list found this diagram of the network, on the web site of the USAF
Rome Air Development Center:
http://www.rl.af.mil/History/Communications/MFSurvivable.GIF .

BTW, the RADC's history page includes a timeline which describes many interesting projects the lab
has worked on since 1951:

I'm going to contact the RADC historian or library to ask if more info is available.
