Real-Time Multiprogramming Operating System

From HandWiki

Real-Time Multiprogramming Operating System (RTMOS) was a 24-bit process control operating system developed in the 1960s by General Electric[1] that supported both real-time computing and multiprogramming.[2][3] Programming was done in assembly language or Process FORTRAN. The two languages could be used in the same program, allowing programmers to alternate between the two as desired.[1] Multiprogramming operating systems are now considered obsolete, having been replaced by multitasking.[citation needed]
