Asynchronous Line Interface

This document provides the technical documentation for the Asynchronous Line Interface, likely for a PDP-11 series computer. It includes a parts list for the DL11-A through DL11-E variations, specifying necessary components such as cable assemblies, crystals, and modems. Additionally, the document contains comprehensive logic diagrams and schematics illustrating the interface circuits, including address selection, interrupt control, line logic, and clock/current loops.
