More on Asimov and computers

In the short story Franchise, Multivac's ability to predict human behavior is so good that it can predict the outcome of an election from interviewing a single voter. Despite that, it communicates with punch cards:
Somehow he had thought Multivac would speak in a sepulchral, superhuman voice, reson and echoing, but that, after all, was just an idea he had from seeing too many television shows, he now decided. The truth was distressingly undramatic. The questions were slips of a kind of metallic foil patterned with numerous punctures. A second machine converted the pattern into words and Paulson read the words to Norman, then gave him the question and let him read it for himself.

Franchise was published in 1955, back in the era where there were separate punch card readers and writers.
