Terminal Control / Asynchronous Data Interface

This document provides comprehensive engineering information for the KL8-JA, a terminal control and asynchronous data interface module designed for Omnibus PDP-8 computers. It includes a drawing directory, detailed schematic logic diagrams (M8655 module), and comprehensive engineering specifications. Key information covers hardware operation, serial data formatting, jumper configurations for baud rates and character parameters, cable distance calculations for 20mA and EIA interfaces, and diagnostic procedures for field service and in-house acceptance testing.
