G831

This document is a technical schematic and parts list for a 6-Bit D/A Comparator & Switch circuit, identified as Drawing Number CS G831-0-1, Sheet 1 of 2, Revision E.

Key elements of the document include:

• A detailed circuit diagram illustrating the interconnections of various electronic components such as integrated circuits (ICs), diodes, resistors, capacitors, and transistors.
• Comprehensive Parts Lists that enumerate all components required for the circuit, providing DEC (Digital Equipment Corporation) part numbers, descriptions (e.g., resistor values, diode types, capacitor ratings, IC models, transistor types), and quantities. These lists also include items like handles, eyelets, and the etched circuit board itself.
• A disclaimer stating that the schematic is for test and maintenance purposes only, that the circuits are proprietary to Digital Equipment Corporation, and are copyrighted 1971.
• Revision History indicating changes made to the drawing.

In essence, it provides the design blueprint and component inventory for a specific digital-to-analog comparator and switch circuit developed by Digital Equipment Corporation.
