M112

This document is a proprietary schematic diagram from Digital Equipment Corporation, copyrighted in 1968, intended for test and maintenance purposes.

It details a circuit titled "NOR GATE M112" (Part Number M112-0-1, Revision D), primarily featuring:

• Integrated Circuits: DEC7402N (E1, E2, E3), which are quad 2-input NOR gates.
• Discrete Components: Capacitors (.01MFD 100V 20% DISC) and Resistors (330 Ohm and 750 Ohm, 1/4W 5% CC), including a network for +5V power (A2) and ground (GND).
• Notes: Specifies standard power connections for the ICs (Pin 7 = GND, Pin 14 = +5V).

The schematic was drawn in February 1968 and engineered in March 1968.
