Maser/VLBI lab at Honeywell (HTSC). Shows a maser along with support equipment. In the pair of racks, at the top, right-hand corner you see one of Tom Clark's original TACs. At the top of the left rack is it sucessor, a first generation CNS Clock from CNS Systems, Inc. The computer screen shows the Tac32 software running. Interestingly, none of the clocks agree; 20:11:11 UTC on 24 May is correct. The Honeywell employee in the picture is Mark Evangelista. Photo by Dr. Thomas A. Clark, included with permission.
