Inverter M111

This document is a technical schematic for the "Inverter M111" circuit board, produced by Digital Equipment Corporation in 1968. The schematic outlines the wiring and component layout for an array of integrated circuits (DEC7400N), resistors, and capacitors. It specifies that pin 7 on each integrated circuit serves as ground (GND) and pin 14 as the +5V power supply. The document includes a parts list detailing the specifications for the resistors (750 ohm, 1/4W), capacitors (.01mfd, 100V), and integrated circuits used on the board.
