W102

This document is a schematic diagram for the PULSED BUS TRANSCEIVER WI02, developed by Digital Equipment Corporation (DEC).

Key details include:

• Purpose: Furnished solely for test and maintenance purposes, with proprietary circuits.
• Copyright: Dated 1964.
• Revision: The document is at Revision N.
• Circuit Components: It details the electronic circuitry, showing numerous transistors (DEC2894-3B, DEC3639B, DEC3009B), diodes (D-662, D-664), resistors, and four transformers (T1-T4).
• Power Supply: Connections for +10V, -15V, Ground, and 0V are indicated. A tantalum capacitor (C1, 6.8 MFD, 35V) is also present.
• General Specifications: Unless otherwise stated, resistors are 1/4W, 10% tolerance, and diodes are D-664.
• Conversion Chart: A "Transistor & Diode Conversion Chart" provides EIA equivalents for DEC part numbers (e.g., DEC3639B = 2N3639, D662 = 1N645, D664 = 1N3606).
• Part Number: The specific document number is WI02-0-1.
