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:
“The jeweled stripes on the window ran straight down when the train stopped and got more and more oblique as it speeded up. The wheels rumbled in her head, saying Man-hattan Tran-sfer Man-hattan Tran-sfer.”
—John Dos Passos (18961970)
