"OKITAC5090H" participated Kyushu University from the design stage was developed in 1963. And, for taking measures to increasing usage of the university’s computation center, a monitoring program was developed for handling jobs with the closed method.
The monitor adopted a batch processing method based on a magnetic tape with a control card system, and consisted of a compile monitor, an execution monitor and a conversion/editing monitor under the surveillance of the parent monitor.
This moniotr system was designed as a spool processing system using the principle of multiprogramming. The conversion/editing monitor haved a special feature that using a magnetic tape as temporarily stored device an execution result with the compilation result were outputted to a line printer or card punch.
