OS/45 Proposal

This document, dated October 20, 1971, contains a memorandum and a proposal for the OS/45 operating system designed for the PDP-11/45. The proposal outlines the marketing and development strategy, identifying real-time and scientific batch processing as the key market focus to compete against IBM. The document highlights the challenges of the PDP-11/45, including a wide price range and new hardware capabilities like memory hierarchies and segmentation. It recommends avoiding commercial batch and time-sharing markets due to resource constraints and intense competition. The proposal also details configuration examples and concludes that OS/45 should leverage upward compatibility to provide a competitive edge in the 16-bit market.
