G060

This document is a proprietary schematic diagram for a "TUILO COMPRESSOR G060" circuit, copyrighted by Digital Equipment Corporation (DEC) in 1969 and intended for test and maintenance purposes.

The circuit features a highly modular and repetitive design, composed of numerous identical stages. Each stage primarily utilizes resistors, diodes, and NPN transistors (e.g., Q1-Q3, Q5-Q7, etc.). A distinct "WRITE ENABLE" control circuit, involving transistors Q37 and Q38, is located on the right side of the diagram.

The document includes a "Transistor & Diode Conversion Chart" which lists DEC part numbers and their EIA/JEDEC equivalents (e.g., DEC 6534B transistors correspond to MPS 6534, and D664 diodes to IN3506). General specifications for components are also provided, indicating resistors are 1/4W 5% (unless otherwise specified), and details on various capacitor and diode types used throughout the circuit.
