Summary of Changes to the V"/370 System 1-1

3031 Attached Processor Complex Support V8/370 Release 6 supports the 3031 Attached Prccessor Co.plex which
consists of a 3031 processor, a 3041 attached processor, a 3036 console
with dual disFlays, and two 3017 power units. Main storage as well as channel and I/O functions are Frovided by the 3031 processor. The 3041 attached processor contains an instruction execution function ana a buffer control function. This enhances the
total system's ability to handle .achine language instructions, reduces
the effective data storage access time, and speeds processing. The
support of this processor requires no code changes to V8/310. PROGRAM LOGIC PUBLICATIONS The following publication contains information on V8/310 support of the 3031 Attached Processor Co.plex: 5Y20-0884 Data Areas and Control Block Logic
