Transistor and Diode Conversion Chart Motion Control

This document provides technical documentation and a parts list for a Digital Equipment Corporation (DEC) motion control circuit board.

• Page 1 contains the component layout diagram for the board, showing the physical placement of integrated circuits (E1-E12), transistors (Q1-Q7), and various capacitors and resistors. It also includes a comprehensive parts list detailing the DEC part numbers for all components used on the board.
• Page 2 provides the detailed schematic diagram of the motion control circuitry. It illustrates the logic gates and connections for control signals such as "Rewind Status," "Forward," "On Line," and "Running." The schematic also includes notes on power requirements and specific transistor/diode conversion details.
