I used the MTS system at the University of Alberta as an Engineering undergraduate in the 1980s. At the beginning of the year, you were budgeted a certain number of CPU seconds which you couldn't exceed. We were VERY careful about not accidentally coding infinite loops. There was a room full of VT100 terminals that we used, but if you needed hard copy, you had to trudge across campus to the building where the burst printer lived.
