The IBM System/370 (S/370) was a model range of IBM mainframes announced on June 30, 1970 as the successors to the System/360 family. The series maintained backward compatibility with the S/360, allowing an easy migration path for customers; this, plus improved performance, were the dominant themes of the product announcement. Improvements over the S/360 first released in the S/370 model range included:
- standard dual-processor capability;
- "monolithic main memory" based on integrated circuits instead of magnetic cores;
- full support for virtual memory through a new microcode floppy disk on the 370/145 and a hardware upgrade to include a DAT box on the 370/155 and 370/165; these were not announced until 1972;
- 128-bit floating point arithmetic on all models.

Famous quotes containing the word system:
“Predatory capitalism created a complex industrial system and an advanced technology; it permitted a considerable extension of democratic practice and fostered certain liberal values, but within limits that are now being pressed and must be overcome. It is not a fit system for the mid- twentieth century.”
—Noam Chomsky (b. 1928)
