System/360

System/360 offered a choice of five processors and 19 combinations of power, speed and memory. A user could operate the same magnetic tape and disk products as another user with a processor 100 times more powerful.

System/360 also offered dramatic performance gains, thanks to Solid Logic Technology - half-inch ceramic modules containing circuitry far denser, faster and more reliable than earlier transistors.

System/360 monthly rentals will range from $2,700 for a basic configuration to $115,000 for a typical large multisystem configuration.

Comparable purchase prices range from $133,000 to $5,500,000.
