This document is intended to be an up-to-date reference manual on the Orion Computer System for those programmers who are most intimately concerned with the system. It is not intended as an instruction manual, but should provide all the detailed knowledge needed by specialist programmers.
It is proposed to keep this document up to date by issuing numbered Amendment-Lists from time to time. Details of all such lists incorporated should be entered on page 0.2 so that it will be easy to find out if any Amendment-List has been missed. Each page of the document is dated.
