Wierd military computer boards

High-res pics at http://www.electricstuff.co.uk/milboards.html Update : Thanks to Jim Lanzafane for the following info : Memories... Thats hardware I designed in the 1980's. It is part of the Military Vax Computer system (MILVAX). We took DECs full size multi cabinet VAX computer, repackaged all the electronics into hermetic ceramic surface mount devices, and double sided conduction cooled modules, all in a USAF ATR chassis.
