[GreenKeys] AN/FGC-30 tape relay description/photos

[Nick England]

 I've acquired a couple of interesting early documents on the Army's FGC-30
tape relay center.

One is a 1953 proposal to the Chief Signal Officer - it includes a photo of
the experimental GGC-2 system installed at Fifth Army in Chicago
Another is a 1956 system description and includes photos of the FGC-30
prototype installed at Sixth Army in Davis.
