Quick Computing If Air Conditioning Worked

(p. 36) Using those IBM 650s was no easy feat. You had to take your turn in line with the other students, write your program, key punch it onto a big stack of cards, do your proofs to make sure it was accurate, and feed it into the computer. If you were lucky and the air-conditioning did not malfunction, you’d get your results back quickly. But there would be errors, which you had to correct, and then you had to repeat the process over and over again until the 650–working on the data with the program that you wrote–came up with the right answers.
