Swift, see if you can track down a digital copy of "Programming Univac
Systems - Instruction Manual 1". I think the copyright was '53. In the
hardcopy version there's a pullout of the complete control panel layout
with a description of every switch and indicator. The manual also goes into
enough detail to walk you through startup, the instruction set, and how to
operate the machine. Pretty cool stuff.
While the Univac II was essentially the same machine (but with core instead
of mercury), the control console became a little more refined and some
photos I've seen show a nixie tube display in place of certain lamps. I
never have found a reference to those refinements. -C
