Going back to the time around 1960, I'd like to venture the opinion that most data processing of the time was performed with unit-record equipment. That is, sorters, reproducing punches, interpreters, accounting machines, etc., none of which were programmed by "software", but by wiring plugboards or selecting operation from fixed controls.
Perhaps there were instructional tests in that area. After all, card sorters pretty much operate on the same principles. --Chuck
