<operating system> (TOS) An IBM operating system for
System 360, used in the early days around 1965 to support
the IBM 360 model 30 et al. TOS was a predecessor to IBM's
Disk Operating System.
TOS died out really early as disks such as the 2311 and 2314
became common with the IBM 360 whereas thet had been a real
luxury on the IBM 7090.
