BOS and BPS for the 360 were on punch cards. the Pitney bowes, later Raytheon, 440 had an operating system on paper tape. they had a large spool with a biderectional high speed tape drive. Type in a command on the console, it would find the needed program, e.g. fortran compiler, load it. compile the program using the card reader./punch, etc. after every job, the paper tape would reload the operating system.
