DECsystem-10 Competitive Analysis

This interoffice memorandum, dated September 22, 1976, provides a competitive analysis of the DECsystem-10 and related hardware against industry competitors, specifically IBM. The document examines the evolution of IBM's System/360 and System/370 product lines, highlighting key developments such as virtual memory, intelligent support processors, and aggressive pricing strategies.

The author, Peter Christy of Software Development, evaluates various architectures (PDP-11, VAX, DECsystem-20, IBM System/370, and HP-3000) based on factors including architecture, implementation, software design, system maturity, and underlying technology. A significant portion of the report discusses IBM's "shocking" price reductions on the 370/138 and 370/148 models, noting that these shifts represent a major competitive threat. The document concludes with a summary of the strengths and limitations for each analyzed system, noting that while VAX is a mature design, it faces initial challenges due to its relative newness and current lack of software investment.
