March 7 Meeting Minutes

This interoffice memorandum records the minutes of the third PDP-11 Electrical Design Review held on March 7, 1969. The document outlines several key architectural modifications presented by Roger Cady, including changes to register configurations, the addition of AC-to-register instructions, and adjustments to addressing modes. The committee also discussed indexed addressing, I/O philosophy, and established a goal to finalize architectural recommendations by March 14, with plans to increase meeting frequency to accomplish this task. Future agenda items include hardware implementation details such as circuits, packaging, cost estimates, power, cooling, and field service policy.
