IBM maintained its position with the System/370, a machine that continued much of the architecture of the 360 but revamped it thoroughly, providing an evolutionary step that could communicate with the past and move toward the future. With the addition of the Winchester hard drive in 1973 and other improvements, the 370 became the mainframe to beat for a decade. It was the last of its line, though, forced later in the 1970s to compete with the PC and the minicomputer, both of which lowered the price of processing power and made it accessible to a new field of users.
