Automatic Circuit Tester

This document from 1964 details the shift from slow, manual production testing of digital logic modules to an automated system using a digital computer. By replacing manual patch-panel and wired-chassis techniques with a system controlled by a PDP-5 computer, Digital Equipment Corporation significantly reduced testing time, decreased costs, and improved reliability. The system automates the testing of logic functions, saturation voltages, fan-in/fan-out, and timing. It also includes data-logging capabilities, enabling easier identification and repair of failed components. The system's flexibility allows for easy reprogramming of test limits and sequences.
