System/370 was a range of IBM mainframe computers. It was first announced in 1970 and the final associated machine was released in 1988.

This item is the overall manual to System/370, but it is by no means a complete guide. Different features of the system will have their own extensive documentation.

From the preface:

'This publication provides, for reference purposes, a detailed definition of the machine functions performed by System/370.

The publication describes each function at the level of detail needed to prepare an assembler-language program that relies on that function. It does not, however, describe the notation and conventions that must be employed in preparing such a program, for which the user must instead refer to the appropriate assembler-language publication.'
