"Whatever was there" was removed before the bunker was declassified.

As far as I understand from the original text (english translation on the blogspam site is incomplete at best), the monitors were installed by the company who now manages the bunker and are apparently used for simulation of nuclear strike on NY, one of the exhibits in Cold War Museum.

Fascinating - one of the most interesting things to me is the characterization of the US soldier on the picture translated (on englishrussia) as "If you forgot where our borders start, we'll help you to land!"

Also the pictures toward the end which, if I'm not mistaken, might have been used as maps and textures in Fallout 3...
