Page of GC20-1834-0 As Updated 1. 1979 by TNL GN25-0486 3031 Attached Processor Complex Support VM/370 Release 6 supports the 3031 Attached Processor Complex which
consists of a 3031 processor, a 3041 attached processor, a 3036 console with dual displays# and tvo 3017 pover units.
Main storage as well as channel and I/O functions are provided by the
3031 processor. The 3041 attached processor contains an instruction
execution function and a buffer control function. This enhances the
total system's ability to handle machine language instructions, reduces
the effective data storage access time, and speeds processing. The
support of this processor requires no code changes to VM/370. PROGRAM LOGIC PUBLICATIONS The following publication contains information on VK/370 support of the
