G7004

This document is an engineering drawing for the "I/O BUS TERMINATOR #2" by Digital Equipment Corporation, labeled G7004-0-1, Revision A.

It primarily features a circuit schematic detailing the interconnections of various electronic components, including resistors, capacitors, diodes, and two integrated circuits (E1 and E2, identified as DEC 2501). The schematic indicates different voltage lines such as GND, -0.7V, -2.8V, and -15V.

General specifications are provided for component tolerances (e.g., all resistors are 5%, all capacitors are .01uF 20% 100V, and all diodes are D662 unless otherwise specified).

A detailed parts list enumerates the required components, giving specific part numbers and descriptions for ICs, various resistors, capacitors, and the etched circuit board itself. The drawing also includes revision history, approval dates (circa Dec 1972), and a proprietary notice from Digital Equipment Corporation.
