I always enjoyed the add-on actuators - a box full of

I have an early 1950's Victor electric (mechanical) calculator
with a typing robot attached, eg. 12 solenoids to push the keys
(100V about 200 mA!). It was built by the Los Alamos Scientific
Lab. I don't think it was used for calculating per se, but as
a data logger/printer.
It's now driven by a PIC, and part of my Story Teller system. Or
was, until the calculator Caught Fire. I'll find another
calculator...
