Notes from PDP-11 Design Review

This document is an internal memorandum from Roger Cady dated April 15, 1969, summarizing key points discussed during the PDP-11 Design Review on April 10, 1969. Topics covered include:

• Considerations for byte addressing, with a request for pros and cons.
• Recommendations for demonstrating sample subroutines (multi-precision arithmetic, floating point, binary-to-ASCII conversion, and TTY handling).
• A discussion regarding TRAP handling and the need for demonstrations of unimplemented routines.
• A request for an instruction or console action to clear interrupt enables across all devices.
• Noted open questions regarding bootstrap loading.
• Handwritten notes regarding an address calculation flowchart and benchmark program sequences.
