Actually fun reminiscing a little. Have not thought about this stuff in decades. One thing I always though was kind of fun. When I started collage terminals were just coming in for students and there was not enough of them. Huge lines. Me I would go over to the row of empty card punches and punch up a deck for my assignment, walk over the the window and give it to the operator and have it read. Then I would get in line for a terminal which by then was often shorter, login, do any editing and debugging, and run and print my assignment in like 30 minutes. Not sure why others did not do this. Just seemed like the way to go.
