Operating systems The 1107 was the first 36-bit, word-oriented machine with an architecture close to that which came to be known as that of the "1100 Series." It ran the EXEC I or EXEC II operating system, batch-oriented second-generation operating systems, typical of the early to mid-1960s. The 1108 ran EXEC II or EXEC 8. EXEC 8 allowed simultaneous handling of real-time applications, time-sharing, and background batch work. Transaction Interface Package (TIP), a transaction-processing environment, allowed programs to be written in COBOL whereas similar programs on competing systems were written in assembly language. On later systems, EXEC 8 was renamed OS 1100 and OS 2200, with modern descendants maintaining backwards compatibility. Some more exotic operating systems ran on the 1108one of which was RTOS, a more bare-bones system designed to take better advantage of the hardware.
