In 1962 Jim Whipple, head of programmers for the UT Computing Center, used the university’s IBM 1620 machine to register 450 freshmen in the College of Engineering in 90 minutes. That saved an estimated two-thousand-person-hours of faculty and student time over manual registration procedures. In winter quarter 1963 the IBM 1620 was used to register the freshman class for the spring quarter. For winter quarter 1969 a program was implemented by which students could turn in “scan sheets” listing the courses they wanted; the computer would then produce the schedule.
