I operated an IBM S/360 model 30, starting in 1972. It had a whopping 64K of memory. Associated equipment: 2540 Reader-Punch, 029 Keypunch, 3420 tape drives, 2311 removable disk drives, 073 card sorter, 1403 impact printer. This was before HASP. So, only one operation could be done at a time. Example: when you were reading in cards, you couldn't be executing a program or printing. Spooling with HASP made it possible to do multiple functions at the same time! HASP (Houston Automatic Spooling Program), used areas on the hard drives for Input and Output queues. A very important DOS command was: Z EOD That's "force end-of-day" and that command would stop any executing program and bring the Operating System down. Then, an IBM CE (customer engineer) could do maintenance on the equipment.
