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:
“If I were sufficiently romantic I suppose Id have killed myself long ago just to make people talk about me. I havent even got the conviction to make a successful drunkard.”
—John Dos Passos (18961970)
