This document is a proprietary schematic for a Digital Equipment Corporation (DEC) "X-Y DECODER SWITCH," copyrighted in 1972 and intended for test and maintenance purposes.

The document includes:

1. A circuit diagram illustrating the interconnections of various electrical components such as integrated circuits (labeled E1-E6), transistors (Q1-Q16), resistors, capacitors, and diodes.
2. A comprehensive parts list detailing quantities, reference designators, descriptions, and part numbers for both electrical (e.g., resistors, capacitors, ICs, transistors, diodes) and mechanical components (e.g., handles, stand-offs, screws, eyelets).
3. A Transistor & Diode Conversion Chart that translates DEC part numbers to their EIA equivalents.

The document is identified as Sheet 1 of 2, with the number G226-0-1.
