Still, gotta love stuff that automates calculations
with purely mechanical
 methods (well, except for the 604) and uses punch cards.  It's basically
 the 20th century version of the Babbage engine. 
Well, electromechanical, as the unit record machines used relays,
solenoids and thyratrons a fair amount.
Still very neat-o.
