I/O Bus Multiplexer

This document provides technical data for the M104 I/O Bus Multiplexer, designed for PDP-15 peripheral controllers. It covers the module's functional role in handling API and data channel requests, including synchronization with I/O processor pulses, priority establishment among devices, and signal management. Detailed tables specify the input pins with their respective load units, output pin driving capabilities, and power dissipation (1W at 5V). A timing diagram is also included to illustrate the sequence of operations for I/O synchronization and bus control.
