Indeed. The 360 early on had a DOS, the little brother of OS/360, and I think even a TOS

single-user OS for the PDP-11. Mostly it was how we did system generation for RSTS-11,
though in my first year in college it also was the OS for the physics department lab
control computer. I fixed that the next year by moving them to RT-11.

According to historians, and I consider myself
one, let us consider what
classic/vintage computers were: The 1970s saw the three amigos: Apple II,
TRS-80 and Commodore PET and the OS was DOS and its ilk + CP/M.
"DOS"??!?
Every operating system called itself "DOS" from 360 through micros.
