M173

This document is a schematic (Number M173-0-1, Revision A) titled "10 AND GATES M173," designed by Nancy Moore on December 16, 1970, and copyrighted by Digital Equipment Corporation. It is provided for test and maintenance purposes only.

The schematic illustrates the logic for ten AND gates, implemented using integrated circuits (labeled E1, E2, E3), along with their associated power supply connections (+5V and +3V) and filtering components (various capacitors and resistors).

Key general notes indicate that:

• Integrated circuits are of type DEC3001.
• For all ICs, Pin 7 is Ground and Pin 14 is +5V.
• Unless otherwise specified, capacitors are 0.01uF, 100V, 20%.

The document also includes a comprehensive parts list, detailing components such as:

• Three DEC 3001 integrated circuits.
• Resistors (330 ohms and 220 ohms).
• Various capacitors (0.01uF disc, 39uF tantalum).
• An etched circuit board.
• Mechanical components like handles and eyelets.
• References to documentation for Module ECO History and layout information.
