G681, G711, G775 Decdisk Modules

This document provides a brief technical overview of three specific Decdisk modules:

• G681 8 Track Matrix: A single-height board equipped with resistors and diodes designed to support eight Decdisk read/write heads.
• G711 RF08 Terminator Board: A single-height board used at the end of a Decdisk cable bus. It features 15 terminating resistors that provide 100Ω to ground for each input pin, with a power dissipation of approximately 90 mW per terminator.
• G775 Indicator Panel: A connector card that isolates logic levels to drive indicator bulbs. It accepts inputs of 0 and -3V, outputs to an indicator board via a Flexprint cable, and has a power dissipation of 150 mW.
