Design Review Committee Meeting 12/22/69

This document is a memorandum dated December 29, 1969, from Roger Cady to G. Butler regarding a final Design Review Committee meeting for the PDP-11. The committee discussed diagnostic philosophy, specifically addressing the need for a modular I/O monitoring system, memory validation testing (questioning the sufficiency of checkerboard tests), and the strategies for production line testing. The memo notes the engineering team's intent to run all diagnostics on the first 50-100 units to avoid past issues, such as the "8/1 CP Tester fiasco." The document concludes by officially closing the design review process and thanking the committee members for their contributions to the final product design.
