This document is an electrical schematic titled "I/O BUS TERMINATOR #3," created by Digital Equipment Corporation.

The schematic details the circuit design for an I/O bus termination module, primarily featuring:

• Components: A network of resistors (R1-R13, including 100Ω and 1.5kΩ values), capacitors (C1-C6, including 3.9µF and 0.01µF values), diodes (D1-D5, identified as D662 type), and two Integrated Circuits (E1, E2, identified as DEC 2501).
• Power Rails: Connections to various voltage levels, including -0.7V, -2.8V, -5V, and +14V.
• Connections: Numerous labeled connection points (e.g., A1, B1, P5, L1, S1, T2) that likely interface with the I/O bus.

Accompanying the schematic are:

• General Specifications: Notes indicating default tolerances for components (all resistors are 5%, all capacitors are 20%).
• Parts List: A comprehensive table detailing the quantity, reference designation, description, and part number for all components, including the etched circuit board, ICs, resistors, capacitors, diodes, and even a "HANDLE, FLIP CHIP - GREEN."
• Proprietary Notice: A statement asserting that the drawing and specifications are the property of Digital Equipment Corporation and cannot be reproduced or used without written permission.
