NOSY: A CORE-SAVING OPERATING SYSTEM,
Abstract
NOSY is a four-phase system: (1) Conversion of BCD input tape to binary tape; (2) Loading and preparation of absolute binary tape; (3) Execution; (4) Output (conversion of binary tape to BCD output). IBSYS is purged from core during the execution phase only. This is the main purpose of the system. Also during the execution phase, the 7040 and 7044 are virtually disconnected, so that the 7040 will eventually hang up, waiting for the 7044 to assign the next 7040 task. This signal cannot be sent until the output phase, when IBSYS is back in core. (Author)
