Overall Design Information
The DG Nova is a system built around a 16-bit word.
All DG and IRIS notation is done in OCTAL. This documentation will primarily use octal unless otherwise indicated. Where helpful, the octal number will be followed by its decimal equivalent in parenthesis, such as: 100 (64).
Documentation should be read in order, as each item builds on concepts presented earlier.
