You have that exactly backwards.
The IBM 360 came with a selection of IBM OSes: TOS/360 (TapeOS), DOS/360 (DiskOS) or OS/360. Versions for smaller machines included BOS and BPS. These were all by IBM.
Other manufacturers copied the IBM 360 architecture, such as the RCA Spectra 70, ES EVM, Armdahl, and others. These either used IBM's OSes or cloned them.
