DOS/360 And Successors
TOS/360 (Tape Operating System/360) was an IBM operating system for the System/360, used in the early days around 1965 to support the IBM 360 model 30 and similar platforms. TOS was a predecessor to IBM's DOS/360.
TOS died out quickly as disks such as the IBM 2311 and IBM 2314 became common with the System/360, whereas they had been an expensive luxury on the IBM 7090.
Famous quotes containing the word dos:
“Theres something wonderfully exciting about the quiet sing song of an aeroplane overhead with all the guns in creation lighting out at it, and searchlights feeling their way across the sky like antennae, and the earth shaking snort of the bombs and the whimper of shrapnel pieces when they come down to patter on the roof.”
—John Dos Passos (18961970)
