Center Tap Selector

This document describes the G286 Center Tap Selector, a single-height hardware module. The module is composed of four AND gates, each driving a power output stage to provide a +20V level to read/write head coils in the RS09 DECdisk Read/Write matrix. The document provides technical specifications, including input voltage levels (0V and -3V), load requirements, output voltage (+20V when enabled, 0V when disabled), input/output delay (500 ns), and power dissipation (1.4W). A logic diagram is also included.
