One camera had a Varitol zoom lens. These cameras were built like tanks, and were introduced in 1962. The Image Orthicon tubes had their own &#8220;look&#8221; that included halos around bright objects, but when properly aligned, they could make\u00a0nice looking black and white video.\u00a0 The photo below was taken &#8220;early-Bob Swanner.&#8221; but &#8220;post-flood&#8221;.\u00a0 Bob was instrumental in making physical upgrades to Tech Center, and one of these upgrades was the installation of a suspended ceiling&#8230;missing in this shot.\u00a0 But the photo also shows a 4 inch drain pipe installed in the ceiling.\u00a0 That puts the photo post-chiller-condenser rupture.
