Computers were scheduled around the clock and users had to get in in at their scheduled time. In addition to fill up their programs, the users had to load (and link, if necessary) any system software, such as compilers and haul drivers, needed for their run. And additional work was required to make the machine available for the next user. Operator Controlled Machines Very soon it became take up that during the rather extended setup and breakdown time the truly expensive computer was not doing useful work. This waste of resources had to be remedied. A computer operator was put in energize of the machine. Users submitted their programs on slug cards.
