I thought it looked earlier and more analog than Univac -- more like
the Rockefeller Differential Analyzer:

http://www.eecs.mit.edu/AY95-96/events/bush/gif/vb21.gif for the RDA

http://www.dpbsmith.com/bushdiffann.html for the relevant movie clip

Another one for the movie list: the visually beautiful but utterly
silly Sky Captain And the World Of Tomorrow (2004), in which the
scientist sidekick uses a slide rule and an oscilloscope to calculate
the location of incoming invading flying robots.
