Pulsed Bus Transceiver W102

This document is a technical schematic for a Pulsed Bus Transceiver (part number W102-0-1) produced by the Digital Equipment Corporation in 1964. The circuit diagram illustrates a complex arrangement of transistors (DEC3639B, DEC2894, and DEC3009 series), diodes (D-662, D-664), resistors, and transformers (T-2044) designed for bus signal processing. It includes power supply inputs (+10V, -15V, and GND) and provides a transistor and diode conversion chart to cross-reference proprietary Digital Equipment part numbers with standard industry (EIA) equivalents.
