I do not remember it, but it sounds like there may be a bit of stretching to me. The 7094 and 7080 that we had at Boeing Wichita at the time weren't nearly that size or power and both ran from tape, IBSYS on the 94 and Supervisory Control System (SCS) on the 80. They were loaded once and there was no time searching for utilities or the like. Usually, the application programs scheduled for the day were written on a tape in the order they were to run. At least SCS had conditional execution of dependent programs.
This was in the 1963-1966 timeframe. A 7094-7044 Directly Coupled System was installed in 1964(IIRC), but I never saw it - a new policy that prohibited programmers from entering the machine room had been implemented - so I don't know if it was on disk; however, I suspect it was. The first S/360 was installed about the time I was drafted in 1966. The 7090 had 32K words, 36 bits each; the 7080, 160,000 BCD characters (7 bits each, including the parity bit). Both measured their times in milliseconds.
